Convert bare Mock() to Mock(spec=bpy.types.Object) for Blender-object
stand-ins in TestRecalculateWallsWithNewConnections, TestMEPActionGuards,
and TestRecreateAggregateIteratesAllNew so typos on the Blender API
fail loudly instead of silently returning a MagicMock.
Replace the ad-hoc Mock() ConnectionRecord stand-in in
TestRecreateConnectionsZipsPairs with a real ConnectionRecord instance,
which pins field names at construction and catches drift if the
dataclass fields ever get renamed.
IFC entity mocks remain bare Mock() intentionally: entity_instance
attributes are schema-driven at runtime rather than defined statically
on the class, so spec= would refuse the .GlobalId / .HasFillings /
.ConnectedTo attribute writes the tests need.

Rewrite tool.Array.select_only_parent as a thin call to

Introduce tool.Array.select_only_parent and wire it into both
bim.regenerate_array and bim.finish_editing_array so post-regen

IfcSurfaceFeature (e.g. road markings) adheres to a host element through
IfcRelAdheresToElement, a [1:1] cardinality hierarchical relationship in the
same family as aggregation, containment and nesting since IFC4.3. The spatial
traversal never followed it, so surface features had no resolvable parent or
container: on import they landed in the Unsorted collection instead of the
host's spatial collection, and were dropped entirely in DECOMPOSITION filter
mode.
Add get_adhered_element (feature to host) to the get_parent resolver chain and
walk HasSurfaceFeatures in get_decomposition, plus a get_surface_features helper
mirroring get_parts/get_contained. With get_parent resolving adherence,
get_container now returns the host's spatial container, so tool.Collector places
surface features under the host. Also follow HasSurfaceFeatures in the Bonsai
DECOMPOSITION filter path so they load in that mode.

file.write() streamed directly onto the target path, so a crash mid-write
left a truncated file with dangling STEP references. Serialize to a temp
file in the same directory, then atomically rename it onto the target.
- New IfcUtil::path::atomic_rename_file: std::rename on POSIX, MoveFileExW
with MOVEFILE_REPLACE_EXISTING on Windows. Unlike rename_file it never
unlinks the destination first, so there is no window where it goes missing.
- Fully in C++/swig (per aothms), so the FILE_NAME header is untouched: it
comes from the model header, not the output path (verified empirically).
- Temp lives next to the target so the rename stays on one filesystem.
- Stream is closed before the rename (Windows cannot move an open file).
- On any write error the temp is removed and the original target is intact.

IfcConvert --version reported 0.8.0 on a plain source build even though the
VERSION file says 0.8.6 (#8164). buildinfo.cpp already falls back to the
IFCOPENSHELL_VERSION_STRING macro and CMake already passes it as
${RELEASE_VERSION}, but RELEASE_VERSION was only read from the VERSION file
when VERSION_OVERRIDE was on. A default build (VERSION_OVERRIDE off,
ADD_COMMIT_SHA off, as the nixpkgs package builds it) fell through to the
hardcoded "0.8.0", so the fallback macro carried the stale value.
Read the VERSION file unconditionally so RELEASE_VERSION is always the real
version. VERSION_OVERRIDE still governs the branch name embedded when
ADD_COMMIT_SHA is on, and project()/CPack now also reflect the true version.

roughnessFactor was computed as 1/specularity. An IfcSpecularExponent of
0 produced infinity, which nlohmann::json serialises as null and makes
the glTF invalid; exponents below 1 produced values above 1, which glTF
also forbids. Map exponents <= 1 to full roughness and keep 1/exponent
above that, so the factor always lands in [0, 1].

The georeferencing fix (e6dc582) iterates IfcProject.RepresentationContexts
unconditionally, but the attribute is OPTIONAL and None on projects without
contexts, crashing every extraction on such files with
TypeError: 'NoneType' object is not iterable.
Also extend the #8199 regression test to assert element placements are

IfcGeometricRepresentationContext.Precision is typed as a plain IfcReal
but is interpreted in the project length unit, so the IfcLengthMeasure
traversal in convert_file_length_units never touched it. A model
converted from mm to m kept a Precision of e.g. 0.01 (fine in mm, huge
in m), which breaks downstream geometry interpretation such as
IfcConvert boolean cleanup.
Subcontexts derive Precision from their parent, so only root contexts
are scaled.

get_info_2 advertises the same signature as get_info but raised a bare

including its own default arguments (recursive=False).
Use the fast path when recursive=True, return_type=dict and ignore=()

format_double formatted doubles with setprecision(max_digits10) (17 digits),
which padded clean values with noise: 0.0174532925199433 was rewritten as
0.017453292519943299 and 1.E-05 as 1.0000000000000001E-05. Every REAL in a file
changed on save, producing enormous diffs for anyone version-controlling IFC.
Use std::to_chars, which emits the shortest string that round-trips exactly
(like Python's repr), then keep the existing mantissa/exponent formatting.
Verified in a standalone compile of the exact function logic: the reporter's
values become 0.0174532925199433 and 1.E-05, 0.1 stays 0.1, and every tested
value (including a denormal) round-trips back to the identical double.

check_aggregate_of_type used an exact type comparison (element->ob_type ==
type_obj), so a numpy array was rejected because its elements are numpy scalars
(numpy.float64) rather than direct float instances. For the numeric types,
accept subclasses: PyFloat_Check for double (numpy.float64 subclasses float) and
PyLong_Check (excluding bool) for int. The SPF REAL vs INTEGER distinction is
kept, so a float is not accepted where an int is expected and vice versa.
This replaces the earlier Python-side walk() approach, which the maintainer
preferred not to take since walk() is removed in v0.9. Verified with a runtime
red-green (built as a shared lib, called via ctypes): the old check rejects
np.array([3.0, 4.0]) and the new one accepts it, plain lists still work, an int
list is still rejected where a REAL is expected, and bool is rejected for INTEGER.

asStringRef removes the first and last characters of a string, enumeration
or binary token to drop the delimiters, guarded only by !str.empty(). A
malformed single-character token (e.g. a bare '.' left when a fuzzer turns
'.PHYSICAL.' into '.)HYSICAL.') has length 1, so the first erase empties the
string and the second erase(str.begin()) runs on an empty string. That is
undefined behaviour: benign on a normal build, but it aborts (or throws
std::length_error from a later append) under a hardened libstdc++ with
_GLIBCXX_ASSERTIONS, which is why this file only segfaulted on the Fedora
build. Require at least two characters before stripping.

generate_linework() loops over the main file plus any linked models
(added in 5db955d4), reassigning drawing_elements each iteration. The
SHAPELY fill pass builds elements_with_faces/raycast_objs from
drawing_elements, but did so once *after* that loop finished, so it
only ever saw whichever file was processed last -- silently dropping
surface fills for every other file, including the main model whenever
any link was loaded.

The underlying bug (has_material_styles bypassing the tool layer) was
already fixed by e76455913, which added the required mock expectation
here, but left the test under its quarantine placeholder name
test_AAAAAAAAAAAA. Restore the real name now that it genuinely passes.
test_memusage_partial_open was silently skipped in CI (psutil was

These packages already have their own pytest suites (ifc5d, ifcedit,
ifcmcp, ifcquery) but were never run in CI, so regressions in them

Fold two related cleanups from post-PR review into one commit:
Shared filling predicate — the gizmo poll and AddOpening._add_openings
both need to decide whether an IFC entity is a Bonsai-supported filling
(IfcDoor / IfcWindow, the classes the opening generator can derive
geometry from). Centralise the check in bim.module.model.opening as
is_filling_supported so a schema-broadening tomorrow only edits one
predicate. The gizmo's own predicate is renamed
is_supported_filling_or_opening to reflect its wider domain (also
accepts None for raw meshes and IfcOpeningElement for reassignment).
Aggregate-host guard — regenerate_filling_opening_body returns the
voided host Blender object so callers can recut it. Aggregates have
no mesh data; returning them made callers hit switch_representation
against a None data-block. Guard on voided_obj.data is None and
return None so callers can skip cleanly.
Adds a direct position_gizmos test asserting host-at-index-1 (filling
active) still anchors on the slab — pins the class-based dispatch's
selection-order independence.

EditOpenings.edit_openings unconditionally walked sibling wall sets
twice on every processed opening — once by mapped source id via
get_similar_openings_building_objs, once by filling type via
get_all_building_objects_of_similar_openings — and unioned both into
the building_objs recut set. reload_body_representation then hit every
one of those walls with a switch_representation call, even for the
show/hide toggle path where nothing about the opening changed.
Move both sibling-wall unions inside the is_edited / is_moved branch.
Pure show/hide (no shape edit, no move) now touches only the wall(s)
directly hosting the toggled openings. The edit and move paths still
refresh siblings the same as before, since a mapped-source rewrite
propagates the new shape to every sharing wall and each one needs a
recut.
Generated with the assistance of an AI coding tool.
recalculate_walls commits the wall's own placement to IFC before
recreating its geometry but did not touch its fillings. A door moved
along the wall's reference line therefore stayed cut at its old
position when the user pressed SHIFT+G on the wall, because the wall
recut ran against the still-stale opening placement in IFC.
Walk each wall's HasOpenings and, for every filling whose Blender
matrix_world differs from its committed IFC placement (tool.Ifc.is_moved),
commit the filling's placement and propagate the new matrix to the
enclosing opening via ifcopenshell.api.geometry.edit_object_placement.
The subsequent recreate_wall pass then sees the fresh opening positions
and cuts at the right spot.

Commit 82dd1d94d switched RecalculateFill from
bonsai.core.geometry.switch_representation to the surgical
tool.Geometry.recut_host to speed up batched host recuts. The trade-off
was intentional for that scope but dropped the implicit opening body
refresh that switch_representation used to provide: SHIFT+G on a door
whose parametric dimensions had drifted from its opening no longer
resized the opening, so the wall recut still hit a stale mapped source.
Extract a targeted single-source helper on tool.Model
(regenerate_filling_opening_body) that regenerates one filling's
mapped opening body via the existing FilledOpeningGenerator and
inverse-substitutes the new representation across every filling that
shares the mapped source. Refactor the family-wide caller
(update_simple_openings, used by the parametric-edit finish path) to
delegate to the same helper, deduped by source id so fragmented type
families where multiple mapped sources coexist all get refreshed.
Call the targeted helper at the top of RecalculateFill._recalculate_fills
for each distinct source among the selected fillings. All body-
representation lookups go through tool.Geometry.get_body_representation
rather than inlining the ("Model", "Body", "MODEL_VIEW") triple. An AST
forward-compat guard pins the call site.

The + gizmo previously appeared whenever a fillable host and any
non-host object were selected, so clicking it against an IfcCovering
crashed the geometry kernel when the opening generator tried to derive
a shape it couldn't build (AttributeError on 'NoneType.wrapped_data').
Tighten the gizmo poll to require the secondary selection to be a
class the operator can dispatch on: IfcDoor, IfcWindow,
IfcOpeningElement, or a non-IFC mesh. Make the poll selection-order-
independent so either click order activates it. Validate the same
class set at the operator boundary so keymap or scripted invocations
report a clear warning instead of crashing.
The narrower Door/Window support in the opening generator is a Bonsai
implementation limit, not an IFC schema restriction —
IfcRelFillsElement.RelatedBuildingElement is typed as IfcElement and
the schema permits any subtype. The tooltip and inline comment on the
validation branch note this so a future reader knows the gate is
future-work, not schema-mandated.
Rewrite the operator's bl_description to end-user-friendly wording that
drops the internal terms matrix_world and rl1/rl2.
Fixes#8215.

Companion to the assign_type.py fix. The same class-pairing validation
added in 10ee5aef4f also gates the Bonsai-side type assignment UI via
tool.Type.is_relating_type_compatible, which the AssignType operator
uses to filter selectable objects. For annotation types (abstract
IfcTypeProduct), get_applicable_types(IfcAnnotation) is empty, so every
annotation was skipped with "No selected object can be typed by
IfcTypeProduct."
Honor the type's ApplicableOccurrence attribute as a fallback, matching
the core API fix. occurrence.is_a() handles subtypes and returns False
for unknown tokens, so free-form text is not trusted blindly.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The class-pairing validation added in 10ee5aef4f rejected every typed
annotation with "IfcTypeProduct cannot type IfcAnnotation ... (allowed
occurrence classes: <none>)".
The check derived allowed occurrence classes solely from the
buildingSMART implementer-agreement map, which has no entry for the
abstract IfcTypeProduct that Bonsai uses for annotation types (IFC4 has
no IfcAnnotationType). The intended occurrence class is declared in the
type's ApplicableOccurrence attribute (e.g. "IfcAnnotation/TEXT"), the
schema-defined mechanism for exactly this purpose.
Augment the allow-list with the ApplicableOccurrence class, but only
when its leading token resolves to a real entity in the schema so
free-form text is not trusted blindly. Genuine mismatches (e.g.
IfcWallType -> IfcWindow) are still rejected.

Three crashes that surfaced when viewport decorators ran against
selected non-IFC blender objects or top-level objects with no
aggregate parent:
- WallAxisDecorator.draw_wall_axis: tool.Ifc.get_entity(obj) returns
None for a non-IFC selection (default cube, lamp, camera). The
subsequent element.is_a("IfcWall") raised AttributeError on every
redraw. Guard with `element and element.is_a(...)`.
- _ConnectedNetworkPathDecorator flow-segment loop: same shape;
iterates entries that may be None, calls .is_a("IfcFlowSegment")
unconditionally. Same guard.
- AggregateDecorator.draw_aggregate: indexes aggregates_list[-1]
unconditionally in the else branch; raises IndexError when the
selected element has no aggregate parent. Also leaves `aggregate`
unbound across loop iterations in the `in_aggregate_mode` branch
when `index <= 0`. Define `aggregate = None` per loop iteration

WallAxisDecorator, SlabDirectionDecorator, FaceAreaDecorator,

cls.handlers, growing a stale-reference list across enable/disable

Refs gh#8088. Array regen + multi-opening drops fan out N+1 wall recuts
per operator (one per child filling deletion + the final mirror recut),
making CSG opening-subtraction O(N^2) for a linear UX action.
Introduces tool.Geometry.batch_host_recut() — a context manager that
coalesces switch_representation and bpy.ops.bim.update_representation
calls per voided element within one operator transaction. The drain
re-reads the active representation so the recut reflects current IFC.
Wraps 7 entry points (regenerate_array, RegenerateArray, RemoveArray,
AddOpening, RecalculateFill, CloneOpening, regenerate_from_type) and
rewires 7 leaf call sites in opening.py, void/operator.py, and
mirror_parent_void_fillings_to_children.
An AST forward-compat guard pins the rewire contract: no direct
switch_representation or bpy.ops.bim.update_representation in the
three target files outside the helper definitions.
A 16-child array regen now recuts the wall once instead of 17 times.

Merging more than two IFC models with the MergeProjects recipe leaves
duplicated IfcGeometricRepresentationContext entities behind. All elements
are kept, but the accumulated contexts cause later disciplines to appear

IfcProject remains, and the geometric contexts are reused rather than
accumulated. It currently fails on the context assertion, reproducing #7973.

EnableEditingExtrusionAxis and EnableEditingExtrusionProfile both
import a mesh from the IFC representation into obj.data as their
first real action. That mesh-import overwrites any in-memory
parametric (gizmo) draft on the object, silently discarding the
user's pending dimension edits.
Concrete reproduction: drag a wall's length gizmo (draft pending),
then click "Edit Axis" before validating the draft. The axis-edit
imports the wall axis mesh; the in-flight draft vanishes; on
cancel the wall snaps back to its pre-drag length.
Both call sites now commit the active draft via

The "mep-pair-fitting" kind added in the previous commit carries an
IfcFlowFitting (the entity whose deletion disconnects the pair), not a
relationship entity, in the dispatch slot — but the slot was named ``rel``
across the function signature and every call site. Rename to ``subject``
so the parameter name reflects the uniform intent: "the entity whose
teardown effects the disconnect", regardless of whether that's a rel or
a fitting.
Sweep covers:
- core.connection.disconnect_rel signature + body
- tool.Connection.find_rels / find_rels_for_element / find_rel docstrings
- The cascade-on-delete call site in tool.Geometry.delete_ifc_object
- DisconnectElements operator in bim.module.model.wall
- All affected test kwargs and AST forward-compat docstring
- Error message: "Unknown rel kind" -> "Unknown kind"

Three user-facing fixes for the MEP-system gizmo surface:
1. MEP pair-disconnect no longer crashes Blender. The
MEPSystemPathDecorator cached entity_instance references in
_cached_walk; deleting a bridging fitting via the gizmo left a freed
SWIG handle in the list, and the next _build_geometry pass segfaulted
on .is_a. The cache now stores STEP integer ids and re-resolves via
ifc_file.by_id on each draw, plus folds tool.Parametric.get_geom_generation
into the cache key — ifcopenshell.api mutations invalidate before the
next frame regardless of how the deletion was routed.
2. Bend re-edit pen icon stays reachable. The bend creation path
tessellates the swept-disk body (upstream geometry-kernel workaround),
so tool.System.has_parametric_body correctly returns False for a
freshly-committed bend. _active_is_bend_fitting and
GizmoMEPActions.is_eligible_object now fall back to the type's
BBIM_Fitting pset — the same source bim.enable_bend_preview_from_bend
reads parameters from — keeping the pen icon eligible.
3. MEP pair / per-port unjoin icons unified through bim.disconnect_elements.
The MEP gizmo group's three unjoin icons (pair, start, end) now share
the wall-disconnect surface: same VIEW3D_GT_wall_link_toggle icon, same
bim.disconnect_elements operator. tool.Connection.find_rels learned a
new "mep-pair-fitting" kind that returns the bridging fitting as the
disconnect target; core.connection.disconnect_rel grew the matching
dispatch arm. The old MEPUnjoinAtPort and MEPUnjoinPair operators are
removed.
Also registered wall.GizmoPairDisconnect (previously declared but never
in the classes tuple, so dead code) for the wall+slab pair-disconnect
surface, and extracted MEP port-topology helpers (find_bridging_fitting,
is_disconnectable_fitting, neighbours_at_ports) onto tool.System so the
canonical walk has a single home.

Two new UX features in the IFC Patch panel, both backed by helpers on
bonsai.tool.Patch.
Lossy-downgrade confirmation popup. When the user picks the Migrate
recipe with a target schema older than the source's (IFC4 -> IFC2X3,
IFC4X3 -> IFC2X3), ExecuteIfcPatch.invoke shows a properties dialog
listing what's preserved vs lost: IfcIndexedPolyCurve flattened with
arcs approximated, IfcPolygonalFaceSet / IfcTriangulatedFaceSet
converted to IfcFacetedBrep, IFC4-only IfcElement subclasses (IfcLamp,
IfcPipeSegment, IfcGeographicElement, ...) demoted to
IfcBuildingElementProxy with the original class + PredefinedType
encoded into ObjectType, and PredefinedType enum values absent from
IFC2X3 dropped. The user explicitly approves before the recipe runs.
The popup is gated on tool.Patch.migration_is_lossy_downgrade() which
resolves the source schema via header-only parsing
(tool.Patch._patch_source_schema reads the first ~2KB and matches a
FILE_SCHEMA regex, then normalises via ifcopenshell.util.schema.
get_fallback_schema). Avoids a full ifcopenshell.open() on every
Execute click — multi-second saving on large files. The target schema
is looked up by argument name rather than position so it survives
recipe-parameter reordering.
Per-recipe preset menu. New BIM_MT_ifc_patch_presets + AddIfcPatchPreset
wire Blender's standard preset system into the panel. Each recipe gets
its own preset subdirectory (bonsai/ifc_patch/<RecipeName>/), so a
preset saved for ExtractElements does not pollute the Migrate preset
list. The preset operator uses Attribute.get_value_name() (single
source of truth for data_type -> storage-field mapping) to build the
preset_values list dynamically per recipe.
The recipe-change callback resets
BIM_MT_ifc_patch_presets.bl_label to the canonical title — Blender's
script.execute_preset mutates the menu's bl_label to the loaded
preset's name as a "currently-selected" indicator, and without an
explicit reset the previous recipe's preset name would falsely advertise
itself in the new recipe's menu.
tool.Patch gains get_preset_subdir, migration_is_lossy_downgrade,
_patch_source_schema as cross-cutting helpers. _SCHEMA_AGE module
constant provides the ordering used by the downgrade-detection
predicate.
Test coverage: 12 bim-lane tests under test/bim/module/patch/. The
truth table for migration_is_lossy_downgrade covers IFC4/IFC4X3 source
x downgrade/upgrade/same-schema target x Migrate/non-Migrate recipe.
The schema-sniffing tests write a real IFC4X3_ADD2 file to disk and
assert the helper resolves it to IFC4X3 (regression for the original
startswith iteration-order bug). An end-to-end test drives
bpy.ops.bim.execute_ifc_patch with an in-memory IfcLamp source and
verifies the on-disk IFC2X3 file contains a single
IfcBuildingElementProxy with ObjectType "IfcLamp/COMPACTFLUORESCENT"
and the original GlobalId preserved.

ExtractElements: expand the `query` docstring to cover the exclusion
syntax (`!` on entity classes, `!=` on attribute / pset / material /
classification / location / group facets) and the "seed with a broad
include before subtracting" gotcha — entity-class exclusion does not
auto-seed from "all elements", so a bare `! IfcSlab` query returns
nothing.
FixArchiCADToRevitDoorSwings: guard the `IfcIndexedPolyCurve.Segments`
loop against the IFC4 case where Segments is absent (a polyline
through all coords in declared order). Previously crashed on
`None.__iter__`.
Generated with the assistance of an AI coding tool.
The Migrate recipe previously crashed mid-loop with the cryptic
`RuntimeError: Entity with name '' not found in schema 'IFC2X3'` when
asked to downgrade an IFC4 or IFC4X3 file to IFC2X3 — the
class_4_to_2x3 mapping marks IFC4-only geometry / element classes with
an empty-string sentinel and the old code blindly forwarded that to
create_entity. Real files routinely contain IfcPolygonalFaceSet,
IfcTriangulatedFaceSet, IfcIndexedPolyCurve, IfcLamp, IfcPipeSegment,
IfcGeographicElement, etc.
The recipe now runs a preprocessing pipeline when the target is IFC2X3
and the source is IFC4 or IFC4X3:
- DowngradeIndexedPolyCurve flattens IfcIndexedPolyCurve to IfcPolyline
for the whole file (arcs included — see below).
- IfcPolygonalFaceSet / IfcTriangulatedFaceSet are converted directly
to IfcFacetedBrep at the entity level via
ifcopenshell.util.shape_builder.polygonal_face_set_to_faceted_brep,
preserving topology including IfcIndexedPolygonalFaceWithVoids inner
bounds. IfcShapeRepresentation carriers have their RepresentationType
tag updated from "Tessellation" to "Brep".
- Orphan source-only geometry instances (left over after the rewires)
are purged iteratively via
geometry_classes_introduced_after(target, source).
The Migrator is invoked with fallback_element_to_proxy=True so
IFC4-only IfcElement subclasses (IfcLamp, IfcPipeSegment,
IfcGeographicElement, ...) become IfcBuildingElementProxy in the
output. A post-pass encodes "<OriginalClass>/<PredefinedType>" into
ObjectType (e.g. "IfcLamp/COMPACTFLUORESCENT") when ObjectType is
empty, so the lost subclass identity survives the downgrade as
searchable text.
The migration loop now collects per-entity failures into a list rather
than crashing on the first; a summary RuntimeError fires at end if any
failed, naming up to 20 with their inverse references. Successful
migrations log a single count line via self.logger.
DowngradeIndexedPolyCurve extended:
- Arc segments (IfcArcIndex) are flattened via
ifcopenshell.util.shape_builder.arc_to_polyline_points with
ARC_SUBDIVISION=16 chord points per arc.
- Multi-index IfcLineIndex segments handled correctly.
- Absent Segments list (IFC4 polyline-through-all-coords case) handled.
Test coverage: 11 tests across the two recipes covering all four
preprocessing branches, the IFC4X3 source gate, the ObjectType
encoding (incl. author-supplied ObjectType preservation), the summary
RuntimeError shape, and the arc subdivision.

Adds the IFC-library primitives the ifcpatch Migrate recipe needs for a
defensive IFC4 / IFC4X3 -> IFC2X3 downgrade without each caller
reinventing the wheel.
In ifcopenshell.util.schema:
- Migrator(fallback_element_to_proxy=False) opt-in: when True, IFC4-only
IfcElement subclasses (IfcLamp, IfcPipeSegment, IfcGeographicElement,
...) migrate to IfcBuildingElementProxy instead of raising. Default
preserves the strict failure-on-unmappable contract for existing
callers (classification API, etc.).
- geometry_classes_introduced_after(target, source) derives the
IfcRepresentationItem subclasses present in `source` but absent in
`target` directly from the loaded schemas. Cached per pair. Replaces
hand-curated class lists that drift with each IFC update.
ifc4_only_geometry_classes() retained as an alias.
- generate_default_value synthesises a unit IfcAxis2Placement2D /
IfcAxis2Placement3D when downgrading entities whose Position became
required in the target schema (IfcIShapeProfileDef and friends in
IFC2X3).
- Enum-mismatch detection upgraded from string-matched RuntimeError to a
structural check via ifcopenshell.util.attribute.get_enum_items so
upgrade paths still surface real bugs loudly.
In ifcopenshell.util.shape_builder:
- polygonal_face_set_to_faceted_brep converts IfcPolygonalFaceSet /
IfcTriangulatedFaceSet (IFC4-only) directly to IfcFacetedBrep,
preserving topology including IfcIndexedPolygonalFaceWithVoids inner
bounds. Validates inputs at the boundary.
- arc_to_polyline_points approximates a circular arc through three
points with a chord polyline of configurable subdivisions. Tolerates
floating-point noise on planar Z. Raises on non-planar or invalid
inputs.
Test coverage: 47 unit tests across schema + shape_builder lanes
covering each helper directly (no transitive-only coverage), including
regression pins for the IFC4X3-prefix ordering invariant in
get_fallback_schema and the strict-default Migrator contract.

Add include_linked_ifc toggle on BIMSceneClipBoxProperties so the cap
pipeline can also bisect meshes inside Project > Links collection-instance
empties. Off by default - linked IFCs may carry the entire site or
structural backbone, and capping them adds per-mesh bisect cost on every
clip-box edit.
The new iterator composes instance.matrix_world @ inner.matrix_world as
the effective world placement so caps land in the active scene rather
than at the linked library's local origin. Linked-mesh cache entries are
namespaced with a 'link:' prefix to avoid collisions with top-level
scene objects.

Promotes the private _fill_quads_alpha helper from
bim/module/model/decorator.py to tool.Blender.draw_quads so any feature
decorator can reuse the same TRIS-batch path.

fill, outline, or both in a single call. Migrates the only existing
caller (WallGizmoPreviewDecorator in model/wall.py) to the public API
and removes the local helper.

Add source-based clip box presets — a dropdown menu next to the Add
Clip Box button lets the user pre-size a clip box to the bounding box
of a chosen IFC source: a spatial element, IFC class, type, material,
profile, drawing camera frustum, status, system, group, or zone. The
picker dialog uses prop_with_search so files with hundreds of materials
or types remain browsable.
Add interactive face resize handles — six near-invisible click-target
quads render on the active clip box when its empty is the active
object. Dragging a face grows or shrinks the box one-sided on that
axis; the opposite face stays fixed. Ctrl+Click on a face aligns the
viewport to look at that face, following Blender's numpad-view
convention applied to the box's local axes so rotated boxes align
orthogonally to the screen. The gizmos honour negative-scale empties
so the visible cube and the clickable handles stay aligned.
Add settings and info menus — a gear-icon menu next to the Enable
Clipping / Show Caps toggles exposes per-file preferences (cap only
IFC products, show face handles); an info-icon menu adjacent documents
the gizmo gestures. A quick-access toggle row also appears in the
viewport Overlay popover, greyed out when no clip box exists, and
orphaned clip-box list entries now expose an X button so users can
recover from external host-empty deletions.
Plumbing: cap rebuild fires synchronously on gizmo release and
clip-box selection change, so the cross-section overlay re-forms
without waiting for the depsgraph debounce; cap eligibility honours
the "Only IFC Products" toggle. Includes 121 tests covering source
resolution, drag math, face visibility, gizmo registration, and the
view-alignment up-axis convention.

Adds a viewport overlay that traces the connected element path from
the selected wall or MEP element. Walls follow IfcRelConnectsPathElements
and draw each connected wall's reference axis with endpoint dots; MEP
elements follow IfcRelConnectsPorts and draw each segment's axis plus
a port-to-port spider for each fitting.
The new BIMModelProperties.show_paths toggle (Element Paths in the
Bonsai Decorators group of Blender's viewport overlay popover) drives
install / uninstall of both decorators on flip and on file load,
mirroring the show_slab_direction wiring. The popover row also
surfaces the pre-existing BIMSystemProperties.should_draw_decorations
toggle (System Decorations) so both connectivity overlays sit
together.
Dot colors split free endpoints (decorator_color_special, blue by
default) from junction nodes (decorator_color_selected, green by
default) so dangling chain tips read apart from interior joins. Walls
classify endpoints by IFC topology: rels expose RelatingConnectionType /
RelatedConnectionType and ATPATH dots use tool.Wall.path_connection_location_world
for the canonical T-meets join. MEP keeps the geometric classifier
because port positions coincide exactly across fitting + segment.

Edit-mode click-select rejected verts inside the clip volume

re-arm at transform-commit, IFC reload, and view drift.
The empty's wireframe was clipped by its own planes when rotated

Per IFC4+, IfcContext is the abstract supertype of IfcProject and
IfcProjectLibrary; library-only files legitimately contain only
IfcProjectLibrary as their root context. Bonsai assumed an IfcProject
was always present at three crash sites: the parent-library enum
(reported in #8183), RefreshLibrary's tree view, and AddProjectLibrary.
Introduce tool.Project.get_root_context() that prefers IfcProject and
falls back to IfcProjectLibrary, and route the three sites through it.
get_parent_library() now returns None for a root IfcProjectLibrary;
get_project_hierarchy() and the EditProjectLibrary parent-swap branch
handle that. AddProjectLibrary creates the nested sub-library via
IfcRelNests when the root is an IfcProjectLibrary, matching the
existing convention for library-under-library nesting.
For the separate "Open IFC Project" path, abort with a friendly error
pointing users to Project Setup -> Project Library -> Select Library
File instead of letting set_units() crash deep in the importer.

IfcQuantity* carries an optional Formula (IfcLabel) documenting how a
quantity was derived. Export it alongside each quantity so it survives
in the Quantities column.
The per-quantity entry shape grows from [name, value] to
[name, value, formula], which stays backward compatible for positional
consumers reading index 0/1. Formula is read with a schema-safe getattr
(it does not exist on IfcPhysicalComplexQuantity, nor in IFC2X3) and is
coalesced to "" when absent.

Adds a viewport clip box feature to Bonsai: a user-controllable oriented bounding box that hides everything outside its 6 faces and draws filled cross-section caps where IFC product geometry intersects the planes.
Quality and coordination > Sandbox > Clip Box
A clip box hides everything outside a user-controllable oriented
bounding box, with cross-section caps drawn where IFC product
geometry intersects the planes. The box is hosted on a Blender
empty (CUBE display); its matrix_world is the single source of
truth — G/R/S edits the empty and the viewport clip planes track.
State persists through IFC save/load via a project-level pset
(IfcProject.BBIM_ClipBoxes) so the boxes survive without binding
to any IfcRoot entity (avoids the IFC scale-lock / strip).
UI: BIM_PT_clip_box under the Sandbox tab. Prominent Enable
Clipping + Show Caps toggles at top, then Add, then a UIList with
per-row duplicate / remove icons. Scene-level enabled / show_caps
so the "hide everything outside" intent applies file-wide;
enabled is intentionally not persisted to the pset so reopening
an IFC never silently hides geometry. Adding a clip box arms
clipping so the user immediately sees the cut.
Default spawn at the 3D cursor with scale 10 (a 20 m cube) so the
volume covers a typical building storey or two rather than the
meaningless 2 m unit cube.
Modal-aware: depsgraph + draw-handler paths gate per-frame side
effects on tool.Blender.is_transform_modal_active so dragging
G/R/S on the box only writes the pset once on commit, not per
frame. Shift+D / Alt+D / Ctrl+Shift+D on a clip box gets adopted
as a first-class entry via the collection-to-list sync.
Cap eligibility is gated on IfcElement (walls, slabs, doors, …)
so spatial structure (IfcSpace, IfcBuildingStorey, IfcSite) and
annotations / grids never sprout solid fills at clip boundaries.
Cap rebuild is debounced behind a 1 s quiet window so external
gizmo drags (and any other burst of non-Bonsai depsgraph updates)
collapse to one rebuild on release. Bonsai's own G/R/S keeps the
snappy on-release feel via a modal-end fast-path. The relevance
filter compares a per-Object matrix hash against a baseline so a
plain selection click — which Blender quirkily flags as a
transform update — doesn't churn the cache or flash the caps off.
Edit mode short-circuits both the rebuild scheduler and the draw
handler entirely.
Caps use the evaluated mesh (modifier stack applied) and a
session/matrix/clip-box-hash cache so a typical scene only
re-bisects meshes whose geometry actually changed.
Performance: every per-frame poller (refresh, depsgraph handlers,
draw handlers) short-circuits on the cheapest available check
first — cap_cache emptiness for the post-view draw handler,
scene_props.enabled for the rest — so a session with clipping
disabled pays only one boolean read per tick.
Known v1 limitations documented in tests / docstrings: hollow
profiles cap as solid discs (single-ring tessellation only),
non-watertight inputs may produce degenerate caps, quad-view
untested, Cycles / EEVEE render not supported (GPU-overlay only).
Generated with the assistance of an AI coding tool.
Bisects a BMesh against a set of planes (clear_outer per plane),
then fills the cut edges as cap faces tagged via a BMesh int layer
so the tag survives subsequent bisects. Cut edges are grouped into
connected components before filling so a hollow profile's outer +
inner loops produce two separate cap faces instead of a single
welded outer face that hides the hole. Pre-welds T-junctions
introduced by IFC Boolean meshes so the cut closes into a fillable
loop.
Callers are responsible for input mesh quality. Non-watertight
inputs (terrain, single-shell surfaces) may produce degenerate
cap faces — that's an accepted user-supplied data limitation
which can be revisited if real-world feedback shows it matters.

product mesh.

Adds geometry primitives the viewport clip-box feature needs:
- obb_world_clip_planes / obb_clip_planes_from_matrix: derive the 6
inward clip planes of an oriented bounding box (or unit cube under
a matrix_world) in RegionView3D.clip_planes form. expand / expand_rel
margins let callers visualising the box with overlapping geometry
(an empty CUBE display sharing edges with the planes) keep the box's
own wireframe inside the clip volume.
- point_is_inside_clip_planes / corners_might_cross_clip_planes: cheap
reject tests for the per-mesh capping pass to skip the expensive
bisect when an object's AABB is fully outside the box.
- newell_normal / plane_basis: robust planar-ring normal for thin
near-degenerate cap rings where a two-edge cross product is unstable.
- tessellate_ring_planar: triangulate [outer, *inners] 3D rings in the
outer ring's best-fit plane, with a shapely constrained-Delaunay
fallback for the known failure mode of mathutils.tessellate_polygon
on complex concave polygons-with-holes.
Tests cover unit-box, translated, rotated, and scaled cases for the
OBB-from-matrix builder + the rejection helpers.

The transform-modal active check (Bonsai keymap macros + Blender's
TRANSFORM_OT_* family) was a module-local helper in drawing/gizmos.py
used by per-gizmo poll callbacks. It needs to be shared with other
features that gate per-frame side effects on whether a drag is in
progress (clip box plane re-arming, future modal-aware decorators).
Move BONSAI_TRANSFORM_MACROS and the gate into tool.Blender as
is_transform_modal_active classmethod; widen its window scan to all
WM windows for callers without a window-bound context (depsgraph
callbacks). Leave a thin module-local alias in drawing/gizmos.py so
AST scans and existing call sites stay decoupled from the helper's
home module.
Also add generic Blender helpers needed by the clip-box feature
(reusable by any future feature):
- iter_view3d_regions: yield (area, region, region_3d) for every
WINDOW region in every 3D viewport — for clip-plane / draw-handler
fanout.
- get_or_create_collection: idempotent named-collection lookup +
link to a scene.
- is_in_edit_mode: True iff the active object is in any EDIT_*
mode — for features that need to suspend per-tick work during
vert/edge/face manipulation.
- serialize_matrix / deserialize_matrix / hash_matrix: round-trip a
4x4 matrix as a 16-float CSV string for IFC pset persistence + a
matching hash for cache keys.

* Tolerate stale array child/parent GUIDs
A real-world IFC project (an arrayed door whose host got deleted
externally) crashed Bonsai's project load with "Instance with
GlobalId not found" inside setup_arrays.
tool.Blender.get_object_from_guid declared Optional return but let
RuntimeError propagate; callers iterating BBIM_Array child lists then
crashed instead of skipping. Honour the documented contract by
returning None on miss, matching the convention used by every other
by_guid lookup helper in tool/array.py, tool/ifc.py, tool/geometry.py.
Sweep the four user-action sites that resolve array child/parent
GUIDs without a guard - they shared the same bug class but were
reachable from different operators (regenerate_array, RegenerateArray
clear, duplicate_ifc_objects, process_arrays). An already-missing
entity is the desired terminal state for each, so the fix is
try/except RuntimeError: continue/skip.
setup_arrays now also collects each parent with at least one stale
child GUID into IfcImporter.broken_arrays, surfaced via a new Project
panel banner mirroring the existing pending_opening_recut UX. The
banner reports the count and offers "Select Elements" to navigate to
the affected array parents and a Dismiss button.
constrain_children_to_parent was being called once per layer inside
setup_arrays' for loop even though it always iterates all layers
internally - lifted out of the loop (pre-existing N x perf bug
that the stale-GUID print exposed).
Regression tests:
- test_returns_none_when_guid_not_in_file pins the get_object_from_guid
Optional contract.
- test_remove_array_tolerates_stale_child_guid injects a fake child
GUID into BBIM_Array.Data and asserts bim.remove_array completes
cleanly.

serialise_cost_quantities built the "Quantities" JSON string by manual
concatenation, inserting quantity.Name and the related element's Name
without any escaping. A name containing a double quote, backslash or
newline produced invalid JSON, breaking any downstream parser (e.g. a
Typst json.decode consumer reporting "failed to parse JSON"). It also
crashed with a TypeError when a name was None (str += None).
Build a Python list and serialise it with json.dumps instead, keeping
the exact same [[name, value], ...] output shape, the element-name
prefix and the unsupported-type behaviour. None names are coalesced to
"" and quantity values are defensively coerced to float.

Wraps three over-length lines black wanted on the merge-filter +

Adds per-test docstrings to test_wall_props_resync_on_dim_change.py
and test_wall_split_filled_opening.py so the contract each pins is

DumbWallJoiner.merge previously crashed on walls with a slab underside
clip because the ConnectedTo / ConnectedFrom migration loops assumed
every rel was an IfcRelConnectsPathElements. The slab's
IfcRelConnectsElements(TOP) rel has no RelatingConnectionType /
RelatedConnectionType and raised AttributeError mid-migration. Filter
on rel class; the slab rel dies with element2 via the trailing
delete_ifc_object cascade.
The fillet preview pen icon now also flips the corner's
BIMWallProperties.is_editing so the connection-disconnect gizmos
surface in parallel with the radius drag. CancelWallFilletPreview
clears the flag before tearing the preview state down so both UIs
hide together. GizmoWallUnjoinSingle.poll inlines the viewport +
array-child guards from the topology gate so the gizmo can show
during preview — its own is_editing check is the real gate.
Fillet-to-source-wall path connection icons render in a muted gray
(LOCKED_COLOR) instead of the active disconnect tone, and the
bim.disconnect_elements operator early-returns with an INFO report
("Fillet wall path connections can't be unjoined — delete the fillet
wall element to remove the corner.") when either side resolves to a
fillet corner. The slab clip rel kind stays disconnect-able since
its identity is separate from the fillet's chord-axis reference.

Two bugs in DumbWallJoiner.split's filled-opening branch:
1. Side classification read filling_obj.matrix_world.translation —
flip-fragile because flip_object rotates the filler 180° + translates
so the bbox stays visually in place, moving the door origin to the
opposite bbox corner. A flipped door centred over the cut could be
classified on the wrong side. Switch to the opening's axis-projected
midpoint, which the unfilled-opening loop already uses.
2. When the void straddles the cut and the filling moves to element2,
the void copy for element1 was taken from the rebound new_opening
whose PlacementRelTo had been swapped to element2 — the new void on
element1 then sat in element2's local frame. Reorder so the copy
reads from the original opening (still hosted by element1) before
remove_feature destroys it.

then sit at the pre-mutation elevation even though the wall mesh shows
the new one — visible asymmetry against the workspace header H field
which redraws live. Add the existing _resync_walls_after_mutation
call to each operator's epilogue. _maybe_resync_wall_props_from_ifc
already skips non-walls and walls in edit mode, so calling on the raw
selection list is safe.

DumbWallJoiner.merge cascade-deletes element2's HasOpenings via
delete_ifc_object, which previously dropped every IfcOpeningElement
(and any IfcDoor / IfcWindow filling) hosted by the discarded wall.
Re-host each void rel onto the survivor BEFORE the delete fires, and
re-apply the opening's captured world matrix via edit_object_placement
so the void doesn't drift when the two walls have different
placements — a PlacementRelTo swap alone would fail this when origins
differ along the shared axis.

Schematic dimensions float in billboarded viewport space; their labels
carry the value, not the bar length. Snapping the dragged tip to scene
vertices produces nonsensical value jumps when the mouse crosses
unrelated meshes. Add an opt-out flag on the parametric gizmo group
base and override it on the schematic base — every schematic subclass
inherits no-snap behaviour, and in-place parametric gizmos (door,
window, wall, stair, roof, mep) keep the existing Ctrl-toggleable
snap because the default stays True.
GizmoDimension.invoke also forces tool_settings.use_snap = False for
schematic gizmos so the header magnet visibly switches off for the
drag's duration. The existing exit path restores the user's previous
setting on release.

Wall body rebuild + slab underside re-clip are now unified behind
tool.Model.regenerate_wall and called from split / merge / extend
operators. Fillet corner walls accept extend-to-underside (poll +
operator partition switched to is_path_connectable_wall) and surface
the wall-unjoin gizmo without the parametric-edit gate, since
fillets cannot enter that lifecycle. DumbWallJoiner.split strips the
duplicate's inherited slab-trim booleans up front so wall2 lands at
the cut point. regenerate_fillet_corner_wall re-clips after the body
rewrite so a prior extend-to-slab survives neighbour recalcs.
Drive-by bug sweep: tuple typo in hotkey_S_G's IfcSpace check,
defensive .get() in draw_regen_operations for partial AuthoringData
loads, and a try/except in get_active_representation matching the
existing convention for stale mesh ifc_definition_ids after a
representation rebuild.
Tests cover the regenerate_wall branching, the get_active_representation
stale-id contract, and the GizmoWallExtendVertically fillet acceptance.

Add a "Copy" option to bim.cad_offset. When enabled (the

Deleting a slab that was connected to a wall via IfcRelConnectsElements(TOP)
left the wall holding orphan IfcBooleanResult items + a stale BBIM_Boolean
pset. The disconnect operator already runs the right cleanup; element delete
just never invoked it.
Extract the per-kind cleanup into core.connection.disconnect_rel so the
operator (bim.disconnect_elements) and a new cascade in
tool.Geometry.delete_ifc_object share one dispatch table. Adding a future
rel kind to tool.Connection.find_rels now flows into both call sites
automatically; an AST forward-compat guard enforces coverage.
Other adjustments:
- regenerate_wall_to_underside zero-slab branch now removes stale clip
booleans instead of silently skipping, so disconnecting the last TOP
slab also reverts the wall correctly.
- duplicate_ifc_objects (Shift+D) calls strip_underside_booleans on copied
walls so the duplicate doesn't carry over the source's slab trim, then
reloads the body representation when something was stripped so the
viewport reflects the change without waiting on Shift+G.
- batch_being_deleted_ids threads through OverrideDelete so the cascade
can suppress partner-side regenerate when both endpoints are queued for
deletion in the same batch.

Wires slabs into the parametric edit framework (tool.Parametric
.EDIT_TYPES) so the wall-slab disconnect UI gets ESC handling, red
cancel icon, mutual exclusion with other parametric edits, and
per-feature gizmo prefs — all from BaseParametricGizmoGroup — without
duplicating the lifecycle.
Adds:
- ParametricObject("slab") registry entry + tool.Parametric.is_slab
predicate (any IfcSlab).
- BIMSlabProperties with is_editing flag; PointerProperty wired by
the framework's register_object_properties.
- bim.enable_editing_slab / bim.finish_editing_slab /
bim.cancel_editing_slab operators on tool.Ifc.Operator so they
flow through tool.Parametric.run_bim_op cleanly. No IFC mutation
— slab edit is a pure UI gate; finish and cancel share the body.
- tool.Model.get_slab_props accessor.
- GizmoSlabEdition inheriting BaseParametricGizmoGroup with the
pen / validate / cancel triad. is_element_type narrows to
IfcSlab with at least one wall clipped to its underside.
The disconnect-icon group GizmoSlabUnjoinWalls polls behind
_slab_connection_gizmo_poll_gate(require_editing=True), which now
reads is_editing through tool.Model.get_slab_props.
Drops the standalone GizmoSlabConnectionAccess + the
setup_pen_cancel_icons helper added earlier in this branch — both
superseded by the framework integration.
Also folds in the wall + multi-slab gizmo polish requested live:
- Wall side: stack the per-slab unjoin icons vertically (up to 5)
so multi-slab connections each get a distinct clickable icon;
hover-highlight reveals which slab will disconnect.
- GizmoPairDisconnect activates when 2 elements with an
IfcRelConnectsElements(TOP) rel are selected, with the icon at
the wall-slab connection world anchor.
- Wall-slab anchor moved from slab clip Z to wall top +
WALL_SLAB_CONNECTION_Z_CLEARANCE so the disconnect icon perches
above the extend-vertical / slope gizmo instead of overlapping.
- Shared _resolve_active_partner_pair helper for 2-selection
gizmos; _slab_connection_gizmo_poll_gate added to
_REQUIRED_CALLEES + GizmoSlabEdition added to the AST
forward-compat allowlist.

Single generic dispatcher replaces UnjoinWallPathConnection +
DisconnectWallSlab. Takes two GlobalIds, looks up every supported
rel between them via tool.Connection.find_rels, dispatches the right
cleanup by rel kind:
- path (IfcRelConnectsPathElements): remove_connection on every rel
in both orientations + recreate both walls + resync drafts.
- element-top (IfcRelConnectsElements with Description=="TOP"):
disconnect_element + regenerate_wall_to_underside on the wall side
via orient_element_top to recover which input is wall vs slab.
- element (other IfcRelConnectsElements): plain disconnect_element.
tool.Connection lands as a new tool module with two helpers:
- find_rels(a, b): every supported rel between two elements, walking
both ConnectedTo + ConnectedFrom (catches both authoring
orientations and dedups by id).
- find_rel(a, b): first-match convenience.
- orient_element_top(rel, a, b): recovers (wall, slab) from a TOP
rel regardless of which input came first.
Updates GizmoWallUnjoinSingle to target bim.disconnect_elements with
both element_a_guid + element_b_guid pre-filled per icon. Adds the
single registration in tool/__init__.py and the classes-tuple entry
in bim/module/model/__init__.py. Drops the two retired classes.
Tests cover both cleanup branches (path + element-top), missing
endpoints, no-rel-found, and registration smoke.

Counterpart to UnjoinWallPathConnection on the wall-slab side: takes
a wall + slab GlobalId pair, locates the IfcRelConnectsElements(TOP)
between them via tool.Wall.find_wall_slab_rel, removes it via
ifcopenshell.api.geometry.disconnect_element, then re-runs
core.regenerate_wall_to_underside so the wall re-clips against any
remaining connected slabs (the disconnected slab is excluded
naturally because the helper walks tool.Model.get_connected_slab_objs
which filters by the rel set).
Defensive reports replace silent CANCELLED on three error paths the
UI can hit when the gizmo dispatches against stale state: unknown
GlobalIds, wall entity without a Blender object, no rel found
between the resolved pair.
Tests cover all four control flows (happy path + three error paths)
plus a registration smoke that catches a forgotten classes-tuple
update.
A follow-up commit will retrofit this + UnjoinWallPathConnection +
the MEP port disconnects through a unified bim.disconnect_elements
dispatcher with a small connection-type registry; that lands as a
separate single-concern commit so the typed operator can be
reviewed first.

Four classmethods enable the new wall-slab connection gizmo work:
- iter_wall_slab_connections(wall): yields (slab, rel) tuples for
every IfcRelConnectsElements(TOP) on wall.ConnectedFrom — the rel
kind extend_walls_to_underside creates.
- iter_slab_wall_connections(slab): mirror, walks slab.ConnectedTo
so a slab-side gizmo can enumerate every wall clipped to its
underside.
- find_wall_slab_rel(wall, slab): locates the specific rel between
a wall + slab pair so a disconnect operator knows what to remove.
- wall_slab_connection_location_world(wall_obj, slab_obj): returns
the world-space icon anchor — wall axis midpoint X/Y lifted to
the slab's mesh-bbox underside Z. Approximate (uses slab bbox vs
reconstructing the slab's clip plane) but adequate for icon
placement on a wall whose top meets the slab; returns None when
the wall has no IFC Axis representation.
Tests (11) pin the rel-shape contract (class + Description=="TOP",
non-TOP and non-IfcRelConnectsElements rels skipped, None relating
defensively skipped) plus the icon-anchor math (axis-mid lifted to
slab-bbox bottom; None for axisless walls).

update_railing skipped the bmesh rebuild for WALL_MOUNTED_HANDRAIL
railings because the only mesh source available at the time mutated
IFC. The viewport-only preview helper that lands with the parametric
gizmo work (generate_wall_mounted_handrail_preview) sidesteps IFC
entirely, so the WALL_MOUNTED_HANDRAIL branch can join the
FRAMELESS_PANEL path and trigger update_railing_modifier_bmesh on
every property write. Gizmo drag now repaints the viewport in real
time instead of waiting for Finish Editing.

Switches the IfcRailingType terminal-type selector from cycle-on-click
to a popup menu of all terminal-type literals — 5+ values trip the
§2.8 menu-pick threshold. Updates classes registration; removes
EditRailingTerminalType in favour of PickRailingTerminalType which
inherits PickTypeMixin.
Adapts the cherry-pick from db016d881 to post-PR5 framework state:
- Imports CycleTypeMixin / PickTypeMixin / PathPreservingEditMixin
from bim.parametric_lifecycle (PR5 moved them off gizmos.py).
- Routes is_railing through tool.Parametric (predicates moved off
tool.Blender.Modifier between PR3-PR5).
Skips the parametric_lifecycle.py framework refactor the source
commit shipped — HEAD has the more-evolved post-PR5 framework that
already covers it.
Adds the _FakePropsBase + make_lifecycle_obj test helpers to
test/bim/conftest.py so the new test_railing_lifecycle.py can
exercise the edit triad without a real bpy.types.Object. Brings the
test_railing_schematic.py marker in line with the rest of the model

GizmoWallEdition.position_gizmos used props.anchor_x / props.length
for the in-range check (split icon visibility) and perpendicular
gizmo placement. Those props mirror IFC and are re-primed by
_maybe_resync_wall_props_from_ifc — any operator path that skips
the re-sync leaves the perpendicular gizmo clamped to the previous
wall extent, so the icon parks at the old wall end instead of the
cursor's orthogonal projection. Visible after a wall mutation as
the perpendicular icon landing way off the cursor in top-down view.
Switch to the mesh bbox along local X. recreate_wall rebuilds the
mesh to match the current IFC body on every wall mutation, so

MEP elements imported as tessellation / brep (no IfcExtrudedAreaSolid
or IfcSweptDiskSolid in their body representation) can't be
parametrically edited — the gizmos offer affordances the geometry
kernel has no path to honour. tool.System.has_parametric_body
inspects the Model/Body/MODEL_VIEW representation and returns True
only when at least one item resolves to one of the two
profile-sweep primitives.
The gate is wired into:
- GizmoMEPActions.is_eligible_object (the action icon group)
- _active_is_flow_segment / _active_is_bend_fitting visibility
predicates the icon row consults per-icon
- GizmoPipeSegmentEdition / GizmoDuctSegmentEdition is_element_type
tool.Parametric.is_pipe_segment / is_duct_segment stay IFC-class-only

and BaseSchematicGizmoGroup all repeat in draw_prepare.
- decorator.py renames _stroke_lines_alpha to a public-scope
draw_polyline_segments and drops the no-longer-private companion
docstring reference; the function is now usable by sibling
decorators that draw polyline overlays.

Two hot paths the gizmo polls fire every viewport event memoise
their result against tool.Parametric.get_geom_generation():
- tool.Blender.Modifier.any_selected_array_child caches the
per-selection scan against the selection identity-set + the
IFC generation token so a stable selection during a drag
doesn't re-walk every selected object's BBIM_Array pset every
frame.
- bim/module/model/wall.py grows a pair-predicate + connection
cache that the wall topology gizmos hit; both keyed on
(pair_uids, predicate_kind, generation) so a wall split or
axis edit invalidates correctly via the generation bump.
Behavioural contract is unchanged — stale entries are evicted
on generation bump; cache miss returns the same value the
un-cached path returned.

Three concerns bundled by file boundary (all in mep.py):
- Extract bend preview operators + GizmoBendPreview into a focused
mep_bend_preview.py module; preview_base.py grows the shared helper
set both bend and other previews now consume; classes tuple in
model/__init__.py updated to register the new module.
- Surface ERROR reports on five silent CANCELLED returns in
MEPUnjoinAtPort / MEPRemoveTerminalFitting / MEPUnjoinPair so a
degenerate IFC file ("fitting has no Blender object", "connected
port leads nowhere") shows up in the popup instead of looking like
a no-op.
- DRY: _resolve_active_mep_segment + _require_port_state factor the
segment-id-or-active-object resolve + port-state guard out of every
port operator's prologue; _wire_anchored_icon_targets pulls the
GizmoMEPActions setup() body into an exercise-without-MRO helper so
the wiring-contract tests can hit it without instantiating the
GizmoGroup.

The opening preview's outline used a single-batch two-pass scheme that
dimmed the occluded back pass via alpha=0.25. The visible front pass also
inherited the source decorator color's modest alpha, so the outline read
as subtle on both sides.
Replace with a CAD hidden-line convention: solid full-alpha front pass on
the visible side, world-space dashed back pass on the occluded side. Both
passes use POLYLINE_UNIFORM_COLOR so depth and line-weight paths match.
The dashed batch is built once per object epoch by a new pure helper
tool.Blender.build_dashed_line_segments (pre-segments edges into world-
space dash chunks), then cached via the existing batch-cache mechanism
under "<uid>_dashed".
The solid front pass is rendered at a slightly wider line width than the
dashed back pass so its halo overpowers Blender's WIRE-display overlay
bias at outline pixels — without the asymmetry the wire's anti-z-fight
forward bias makes the LESS_EQUAL comparison narrowly fail and the
dashed pass wins on visible edges too.

canonical corners; anything else returns None so the rep swap
is skipped rather than meshed against the wrong section
- parallel-transport framing keeps the cross-section continuous

- initial_basis override seeds the first ring with the source
segment's local +X / +Y axes, fixing the asymmetric-rectangle
twist the world-Z seed produces

Pins which IFC mutation each port operator commits and which
inputs each refuses with CANCELLED:

the segment's port free; refuses on bridged fittings

Pins two regressions the live MEP gizmo group can hit:
- per-icon setup() must write `position` (and `mode` on open-lock

when a field was dropped from the operator declaration
- each visibility_condition lambda must stay total against None /

ProfileDecorator.draw_faces (used by the roof path-edit overlay) and
SystemDecorator.draw_faces called bmesh.ops.triangulate on the live
bmesh — both mutated the input and produced ear-clip fans that rendered
as visible streaks across n-gon roof faces at alpha 0.1. The opening
DecorationsHandler edit-mode branch had a separate bug: it computed
triangles from obj.data.calc_loop_triangles() while iterating the
edit-mode bmesh, so any topology added mid-edit desynced the indices.
Centralise the correct draw path on tool.Blender.draw_bmesh_face_tris
(wraps bm.calc_loop_triangles, non-mutating, beauty triangulator) and

A user clicking the pen icon on a typed-product occurrence whose body
representation is mapped from its type would silently mutate every
sibling occurrence's geometry. Add a confirmation dialog at the pen-icon
dispatcher (the single chokepoint every feature routes through) showing
the sibling count, with a session-scoped suppress checkbox.
The check is read-only: tool.Model.get_sibling_occurrence_count wraps
tool.Geometry.get_elements_by_representation against the resolved body
rep and subtracts self + type. A forward-compat AST guard pins the
dispatcher monopoly so any future feature that binds pen_gizmo directly
to a feature-specific enable op fails the test before merge.

Once a bend was created, the only way to retune start_length /
end_length / radius was to delete and recreate from scratch.
EnableBendPreviewFromBend re-opens the preview on an existing
parametric bend: it walks the bend's ports to resolve the two
connected segments, reads start / end length and radius from the
bend type's BBIM_Fitting pset, and sets editing_bend_id on the
preview props. MEPAddBend then deletes the old bend + its port
connections (single undo step) before the recreate path runs, so
finish replaces the bend in place and cancel discards the edit
without touching the original.
GizmoMEPActions surfaces a pen icon on single bend-fitting
selections via the new _active_is_bend_fitting predicate; the icon
dispatches the new operator. Mirror of the wall fillet re-edit
flow (EnableWallFilletPreviewFromCorner + editing_corner_id in
CreateWallFillet).
Test coverage: registration probe for the new operator, an attached
editing_bend_id field probe on the preview umbrella, and a

(IfcFlowFitting with BEND PredefinedType, with other PredefinedType,
with no type, IfcFlowSegment, IfcWall, None).

Wall topology mutations (merge / join / extend-to-wall / unjoin /
fillet) applied to a Bonsai array child are silently overwritten by
the next ``regenerate_array``; merge also orphans a GUID listed in
the parent's ``BBIM_Array.Data``. Add a central
``tool.Blender.Modifier.any_selected_is_array_child`` predicate and
gate the five wall topology gizmo groups plus the six bound operators
behind it. Operator gating is defence in depth against keymap / F3
invocation paths that bypass the gizmo.
The base ``_wall_gizmo_poll_gate`` keeps its loose two-check shape
(viewport gizmos + no preview). A new
``_wall_topology_gizmo_poll_gate`` wraps it with the array-child
filter and is what the topology gizmos use. Host-opening gizmos
deliberately stay on the loose gate: openings authored on a child
are preserved through ``regenerate_array`` and track with the
replicated instance.
A forward-compat AST guard walks wall.py for ``GizmoGroup`` subclasses
and asserts each routes its poll through the tighter gate or the
central predicate, with an allow-list for the parametric-edit and
preview-owner exceptions. New wall topology gizmos inherit the
contract by construction.

Selecting a Bonsai-parametric IfcDoor now shows the swing arc(s)
without entering edit mode. A new viewport decorator polls on the
active object, reads the door's BBIM_Door pset, and draws the same
arcs the parametric door swing gizmo would draw — matching the
hinge / panel-width / x-mirror contract minus the is_editing gate.
A forward-compat test walks every door operation type and cross-
checks the readonly decorator's arc selection against the gizmo's
swing-arc config table, so future enum additions fail in both
surfaces simultaneously.
Also disables the inherited 8-pass dark halo on GizmoArc: an open
curve has no enclosed silhouette, so the offset passes read as
ghost arcs rather than a uniform outline. The arc's own cross-
section thickness keeps it legible without the halo.

The MEP bend feature's IfcSweptDiskSolid representation produces
geometrically correct output but fails to round-trip through the
OpenCascade geometry kernel (upstream issue #8106) — the body is
dropped on the next file load. Until upstream is fixed, MEPAddBend
captures the bend centerline in world space before the segments are
extended (otherwise the post-extension axes no longer reach the
original intersection and arc reconstruction is wrong), then after
the fitting is placed it hand-meshes the bend body and swaps the
type's swept-disk representation for an IfcTessellatedFaceSet via
tool.Geometry.export_mesh_to_tessellation + tool.Model.
replace_object_ifc_representation.
The centerline includes the straight start_length / end_length legs
in addition to the arc so the bend covers the full segment-to-
segment span. Sweep uses parallel-transport framing — each ring's
(right, up) basis is rotated by the minimum rotation that maps the
previous tangent to the current one, eliminating the twist a fixed
world-axis reference produces when the tangent crosses the
reference. Cross-section orientation seeds from the source segment's
matrix_world local +X / +Y so asymmetric IfcRectangleProfileDef
ducts land with XDim / YDim on the same axes the segment expects;
parallel transport then preserves that alignment around the arc.
Centerline radius is radius + profile_dim[lateral_axis] to match
MEPAddBend's ref_point_radius — without this offset, the bend legs
fall short of the extended segments by profile_dim * tan(angle/2).
Face winding is left to the caller to correct via
bmesh.ops.recalc_face_normals on the closed bend tube.
Two FIXME(#8106) markers (capture site + helper call site) so both
can be dropped once upstream lands a swept-disk round-trip fix.

GizmoWallEdition gains a fourth cursor-anchored icon that
spawns a perpendicular branch wall from the cursor's
orthogonal projection on the source wall axis. Click forms
a T-junction; shift+click forms an L-corner with the source
wall trimmed at the projection, keeping its longer portion.
The branch inherits the source's spatial container and
centerline baseline so its authored axis matches the source's
alignment rather than the type's default.
Also includes a floor-plane preview quad for the new gizmo,
a floor-Z cross line on the split preview for top-down
visibility, a small bump to QUAD_ALPHA for clearer preview
fills, and a stacking-offset helper that centralises the
cursor-row screen-up step across three call sites.

The MEP one-shot operators (join, unjoin variants, terminal removal,
path-select, obstruction add/remove) had no viewport surface. This
commit adds GizmoMEPActions — the icon-action gizmo group that
surfaces them as billboarded icons around selected MEP elements.
Three anchor regions: a horizontal row above the bbox top
(selection-cardinality icons), per-port endpoints for the three-state
lock / unjoin icons (open lock for PORT_FREE, closed for
PORT_TERMINAL, unjoin for PORT_JOINED — resolved per-frame from
port_connection_state), and the predicted join location
(compute_mep_join_location, shared with the bend preview) for the
join / unjoin_pair pair. Unjoin icons render at full
DEFAULT_BILLBOARD_SCALE with warning-red hover; endpoint lock icons
shrink so the lock row stays subordinate to the row icons. The
group hides itself entirely while a bend preview is active.
MEPAddObstruction grew a position enum (CURSOR / START / END) and a
mode enum (ADD / REMOVE / TOGGLE) so the gizmo can target a specific
port without touching the cursor and dispatch ADD or REMOVE based on
the click target — the lock_open icons drive ADD with position
pinned, the lock_closed icons drive bim.mep_remove_terminal_fitting.
Without the new fields the gizmo wiring (op_props.position = ...)
crashed at setup() with AttributeError on the obstruction operator.
validate_bend_preconditions extracts the type-match and profile-kind
checks MEPAddBend enforces so EnableBendPreview surfaces the
rejection immediately — the user no longer tunes a preview only to
learn at commit time that the segments use an unsupported profile
(e.g. IfcArbitraryClosedProfileDef).

Four discrete one-shot operators driven by the MEP segment's port
state. mep_unjoin_at_port deletes the IfcFlowFitting bridging a
segment's named port to a second element when the port is in the
JOINED state. mep_remove_terminal_fitting deletes the terminal
fitting at a port (closed-lock state) and dispatches by fitting
type — OBSTRUCTION fittings go through MEPGenerator.remove_obstruction
so the segment absorbs the freed length, other terminal fittings go
through the standard delete path. mep_unjoin_pair finds the single
fitting bridging two selected MEP segments and deletes it.
select_mep_path_members walks the connected MEP network from the
active element via IfcRelConnectsPorts and replaces the selection
with every reachable member. Foundation for the MEP Actions gizmo
group which surfaces these operators as icon affordances around
selected segments.

The extend icon used a pure screen-space billboard that always
pointed +X across the screen — the arrow ran horizontally
regardless of the pipe / duct's orientation. The new
billboarded_along_axis helper rotates the gizmo about the camera-
forward axis so its local +X aligns with the segment's local +Z
projected onto the screen, keeping the icon camera-facing but
visually following the extrusion direction. The flip-mirror branch
now reads from cursor-vs-current-end along the segment axis (not
screen-X), so the arrow points away from the current endpoint
regardless of viewport orientation. The split icon stacks
perpendicular to the rotated extend arrow in screen space so the
two don't overlap.
The decorator's green preview line no longer clamps the cursor
projection to min_projected_length — it follows the raw projection
so the line stays visible when the cursor crosses behind the
segment origin (the user still sees where they're pointing even
though the operator floors the actual commit).

The bend preview gizmo group (commit 2) populated a Scene draft but
the user saw nothing in the viewport until they hit finish — they
had to commit blindly. This commit ports the BendPreviewDecorator
(centerline arc + two leg projections on valid geometry, warning-red
axes on invalid in-segment intersections) and the interactive
GizmoBendPreview group (three dimension widgets for start_length /
end_length / radius plus validate / cancel icons). The bend axis
math lives in a pure compute_bend_preview_polylines helper, fed
into both the gizmo group's per-frame positioning and the GPU
decorator's draw path. MEPSegmentExtendPreviewDecorator lands at
the same time because it shares the decorator install / uninstall
plumbing — renders the extend-to-cursor preview line for the
GizmoPipeSegmentEdition / GizmoDuctSegmentEdition extend icons
when hovered, clamping the projected endpoint to the operator's
minimum so the preview matches where the commit lands. The
MEPJoinSegments dispatcher routes two selected MEP segments to
mep_add_transition (parallel) or enable_bend_preview (non-parallel)
— the F3 search entry point that makes the bend preview testable
before the gizmo-icon dispatch lands.
11 new tests in test_mep_bend_preview.py cover the geometry helper
truth table (parallel rejection, right-angle happy path, near-
collinear rejection, in-segment invalid_axes), the
_intersection_past_near parametrized boundary, registration probes
for the lifecycle operators / join dispatcher / gizmo group /
decorator, and the FinishBendPreview RuntimeError catch contract.
6 extend-preview-line tests (deferred from commit 3) join the
existing 35 in test_mep_segment_edition.py.

Spatial.get_root_element walks aggregate / nest / filled-void /
voided-element chains and core.assign_container assigns the container
to whatever the walk returns. For an IfcDoor the filled-void hop
redirects to the IfcOpeningElement, then voided-element to the host
wall, so a user who selects a door and runs bim.assign_container ends
up targeting the wall — and silently no-ops on the door if the wall is
already in the target storey.
Per IFC4 / IFC4.3 (IfcDoor, IfcWindow): the spatial containment of a
filling is defined independently of the filling relationship. Major
exporters (Revit, ArchiCAD, Tekla, Allplan) emit independent
ContainedInStructure on doors / windows accordingly. Drop the
filled-void / voided-element hops from the walk; aggregate and nest
remain — those are true sub-part relationships where the parent
legitimately owns the container.
New TestGetRootElement in test/tool pins the new contract (filling
resolves to itself) plus the retained aggregate / nest / loose-element
paths so a future PR that re-adds either hop is caught. Two new
TestAssignContainer cases in test/core pin filling-to-self through the
core layer and per-element can_contain filtering.

Pipe and duct segments had no parametric-edit affordance — the only
length edit path was a property panel value with no live preview.
This commit ports the per-segment parametric edit triad
(enable / finish / cancel) plus a cursor-anchored extend operator
and a cursor-projected split operator into one gizmo group per
segment type. The two PropertyGroups (BIMPipeSegmentProperties,
BIMDuctSegmentProperties) host the draft length plus snap fields
so cancel / no-op-finish restore the segment to its exact pre-edit
visual state including a non-identity pre-edit scale. Length
commits are written through DumbProfileJoiner.set_depth and
auto-dispatch bim.regenerate_distribution_element so adjacent
fittings track the port move. The split operator preserves
downstream port connectivity and runs through tool.Ifc.run for
single-step undo. The two segment types are now first-class
entries in tool.Parametric.EDIT_TYPES, which resolves the FIXME
on auto-commit-on-save dispatch.
35 unit tests cover predicate truth tables, segment_world_length
geometry, preview-via-scale / restore-scale helpers, gizmo class
wiring, lifecycle operator registration, dimension matrix_position
rotation respect, and lifecycle drift-handling. The 6 extend-
preview-line decorator tests stay deferred until the bend preview
decorator commit lands MEPSegmentExtendPreviewDecorator.

Parametric gizmos (wall/door/window/stair/roof/array/MEP) recompute
matrix_basis every frame from obj.matrix_world. While Blender's
transform modal (G/R/S and the Bonsai macro overrides) drags the
matrix, the gizmos slide off-cursor and fight the transform overlay.
Detect via context.window.modal_operators (Blender 4.2+) — the
collection of running modal operators. Gate poll() (forward-compat)
and draw_prepare() (production path: gizmo.hide=True preserves the
GizmoGroup across the drag instead of destroying it). Cover the
Bonsai macro override for G key (and Shift/Alt/Ctrl+Shift+D) by
matching the BIM_OT_* macro idnames that surface in modal_operators.
Forward-compat test walks every parametric-edit module for GizmoGroup
subclasses and asserts poll returns False with the detector mocked,
so new gizmo groups inherit the hide automatically.

Every preview operator (commit + cancel for both bend and wall
fillet) was inlining the same 3-4 line cleanup: set is_active to
False, zero every *_id IntProperty. The new clear_preview_state
helper in preview_base.py introspects bl_rna and applies that
contract generically — adopters become a single call. Two new tests
pin the contract: every *_id IntProperty zeroes, non-id fields stay.

MEPAddBend exists on the main flow but commits bend geometry with
hardcoded defaults (start_length=0.1, end_length=0.1, radius=0.2)
with no opportunity to tune before commit. The new scene-level
BIMBendPreviewProperties hosts a draft (start_segment_id,
end_segment_id, start_length, end_length, radius); EnableBendPreview
populates it from the two selected MEP segments after asserting they
are non-parallel, FinishBendPreview dispatches MEPAddBend with the
tuned values and clears the draft, CancelBendPreview discards it.
Scene-level placement follows CLAUDE.md 2.9: a bend creates a new
fitting entity between two segments, so neither segment alone owns
the draft. Foundation for the upcoming bend preview gizmo group and
decorator.

When an operator mutated IFC then raised mid-execute the user was left
staring at a raw traceback with the IFC graph captured by the active
transaction but the Blender side stale. Blender does not push an undo
step for a raised operator (the same gap that the CANCELLED-modal arm
patches via bpy.ops.ed.undo_push), so the WARNING the framework can
emit is only honest if it pushes that undo step too. The framework
now detects partial state via ifc_file.transaction.operations,
pushes a Recover undo step, then reports a WARNING naming Ctrl+Z so
the recovery path is discoverable. The bespoke try/except wrapper in
UnjoinWallPathConnection becomes redundant and is retired in the
same change.

The toggle_openings icon lived outside the IconSlot layout — each
host (wall, roof) declared an ad-hoc setup_pen_row_toggle_openings_icon
+ update_pen_row_toggle_openings_icon pair, and GizmoArrayEdition
queried a hardcoded _FEATURE_IDLE_MAX_X dict to position past it.
On an arrayed wall the dict was shadowed: find_for_element returns
"array" before "wall" in EDIT_TYPES order, the wall reservation was
never consulted, and the first per-layer ARRAY icon (local X=0.37)
landed 13cm from the wall's toggle_openings (X=0.50) — visually on
top of each other.
Promote idle-row icons into the slot system instead of patching the
dict:
* IconSlot gains an Optional visible_when predicate for state-driven
visibility (toggle_openings only when the host carries openings).
* BaseParametricGizmoGroup gains idle_slots: ClassVar[tuple[IconSlot]]
+ _idle_slot_x_positions() + _idle_row_right_edge() helpers; the
setup + idle-branch positioning loops mirror the existing
feature_slots path.
* Wall and roof declare toggle_openings as an idle_slot and drop
their ad-hoc setup/update calls.
* GizmoArrayEdition's _resolve_feature_idle_max_x walks
BaseParametricGizmoGroup.REGISTRY and takes the max
_idle_row_right_edge() across peers whose poll passes — no more
hardcoded dict, no more find_for_element-order shadowing.
* setup_pen_row_toggle_openings_icon + update_pen_row_toggle_openings_icon
helpers deleted from drawing/gizmos.py.
* 3 forward-compat AST guards pin the new contract.
Also bundles an unrelated array-test fix: TestUsingArrays in
test/tool/test_model.py was asserting against bpy.context.selected_objects
which is a fragile signal after remove_array / apply_array. A new
_array_objects() helper filters bpy.data.objects via the BIM_Array
pset's IfcActuator type instead.
Layout on an arrayed wall after the fix:
pen X = 0.00
toggle X = 0.50 (idle_slot 0)
array[0] X = 0.87 (one ICON_ARRAY_GAP past idle row)
array[1] X = 1.27
All separated by the standard inter-icon spacing.

In plan view world-Z collapses to zero on screen, so every wall-edit
icon anchored on the floor — the projected 3D cursor, wall endpoints,
wall-to-wall corners, IfcRelConnectsPathElements connection points —
projects onto the click target it represents. The result on a typical
extend / split / unjoin action: the icon sits on top of the cursor
crosshair (or the corner the user wants to click), defeating precise
positioning.
Add shared ``gizmo.top_down_clearance(context, billboard_rot)`` to
bim/module/drawing/gizmos.py: returns a screen-up Vector in top-down
view (cosine cone around world Z, matching ``is_view_top_down``) and a
zero Vector elsewhere, so call sites apply it unconditionally before
``billboarded_at``. Default distance 0.4 m aligns with the inter-icon
stack spacing already used by GizmoWallJoinIntersection so single
icons and stack bases land at consistent screen-up positions when
multiple groups render around the same wall endpoint.
Apply at the seven wall-edit anchor sites:
* GizmoWallEdition cursor stack (top-down branch only — non-top-down
already stacks along world-Z at structural points clear of the
cursor).
* GizmoWallExtendVertically (single icon at wall origin endpoint,
active-object Z elevation).
* GizmoWallJoinIntersection corner stack base + merge midpoint.
* GizmoWallUnjoinSingle link-toggle pool (one icon per IFC path
connection, previously sitting exactly on the connection point).
* GizmoWallFilletReedit pen icon at fillet corner.
* GizmoWallFilletToggleOpenings.
The clearance is a pure visual offset — bound operators still read
the world-space anchor (cursor / endpoint / connection point) at
execute time, so the action's target is unaffected.
Also tighten GizmoWallUnjoinSingle: gate poll on ``props.is_editing``
so the link-toggle icons only surface during the wall edit lifecycle
(matching every other edit-row icon), and downsize them via a new
``ICON_SCALE = 0.35`` constant since 16 of them at default scale
cluttered the viewport on path-heavy walls.

Some distributions (e.g. Fedora) ship only a shared RocksDB that exports
RocksDB::rocksdb-shared rather than RocksDB::rocksdb. The CMake target
selection now falls back to the shared target when the static one is absent.
Newer RocksDB also changed DB::Open and DB::OpenForReadOnly to take
std::unique_ptr<DB>* instead of DB**. IfcFile.cpp uses SFINAE tag dispatch
to build against both old and new APIs without version detection.
CGAL 6.x deleted operator< from Point_d, so std::map<Point_d, ...>

bim/handler.py was importing two feature-module internals
(wall_offset_gizmos.clear_caches, preview_base.discard_pending_previews)
to drain load-transient parametric state alongside the existing
tool.Parametric.heal_stale_edit_flags() call inside
_apply_save_file_invariants. Each new parametric drain added one
top-level import and one inline call — every load_post drain leaked
into handler.py's namespace.
Hide all three drains behind tool.Parametric.on_load_post(scene),
sited adjacent to heal_stale_edit_flags. The two feature-module
imports become late imports inside on_load_post — same pattern as
refresh_post_commit's existing `import bonsai.bim.handler` — which
sidesteps the tool.parametric -> bim.module.model.preview_base ->
bonsai.tool registration-time cycle.
The forward-compat AST contract that pinned "every module-scope
GenerationKeyedCache + clear_caches MUST be drained on load_post"
follows the call site to its new home — the test now walks
tool.Parametric.on_load_post instead of _apply_save_file_invariants.

Three concerns sharing the same architectural theme (collapse inline
bbox / edit-state lookups, drop overrides that re-do base-class work):
== Bbox helpers and array operator DRY ==
* tool/blender.py: add a "dimensions" tuple key to both
get_object_bounding_box and get_object_world_bounding_box return
dicts. The (max - min) per-axis extent — which callers previously
computed via local helpers — is now a key alongside min_x / max_x
/ min_point / max_point / center. Distinct from Blender's built-in
obj.dimensions (which folds object-level scale): the local variant
is the intrinsic mesh bbox extent; the world variant is the
matrix_world-applied AABB.
* bim/module/model/array.py: drop the local _bbox_dims helper; the
two callers now read tool.Blender.get_object_bounding_box["dimensions"]
directly.
* Rename _parent_geometry_changed -> _array_children_need_rebuild.
The old name suggested "did the parent change just now", implying
the function was a parent-edit-finish trigger. It actually runs
only inside the array-edit-finish path as a drift safety net (the
upstream-deliberate design — see commit 83d97d7e9 "Fix #7616. Make
regenerate array an operator instead of an array preference" —
means the array doesn't auto-regen when its parent geometry edits
finish). New name matches the call-site phrasing
``if X: _wipe_array_children(layers)`` and clarifies that this is
a children-state check, not a parent-edit trigger.
* Extract _resolve_array_edit_props(context) — returns the active
object's array props during an active edit lifecycle, or None.
Collapses the obj-active-then-is-editing prologue (3 lines + return)
to one resolver call across 4 sites: ToggleArrayMethod.execute,
AdjustArrayCount.execute, RemoveArrayLayerFromEdit._execute and
.poll. Each call site shrinks from 7 lines to 3.
* Migrate two inline bbox reads inside GizmoArrayEdition to the new
dict keys: get_axis_world_face_center collapses the manual
xs/ys/zs min/max + center math to bbox["center"] + bbox["max_x"] /
["max_y"] / ["max_z"]; get_element_height collapses
``max(corner[2] for corner in obj.bound_box)`` to
tool.Blender.get_object_bounding_box(obj)["max_z"].
The _BBOX_EQUALITY_EPS = 1e-5 tolerance stays inline as a single-
consumer constant — no other call site needs tolerance-equality on
dimension tuples, so extracting it to a shared util would be
speculative abstraction.
== Drop dead code ==
* GizmoArrayEdition.update_editing_gizmos override + its
_has_other_parametric_type helper: redundant with
hide_pen_button = True at line 1024. The base class already hides
the pen in every idle case (when hide_pen_button is truthy) AND in
every editing case (unconditionally). The override's conditional
hide-when-parametric only re-hid a pen that was already hidden in
both branches. Removes the only remaining path that could re-show
the array's pen icon; array-edit entry is now uniformly via the
per-layer ARRAY icons (which is the documented preferred
affordance, see the hide_pen_button comment).
* _wall_fillet_preview_active in wall.py: defined but never called.
_wall_fillet_props (the sibling thin-wrapper around
preview_base.get_preview_props) is heavily used; the
is_preview_active wrapper was added speculatively and never picked
up a consumer.
Generated with the assistance of an AI coding tool.
Bundled bug fixes + the forward-compat AST guard that prevents the
underlying class of bug from coming back.
* bim/module/model/wall.py: FinishEditingWall._execute early-returns
CANCELLED when props.is_editing is False. Without this guard, a
failed enable (e.g. on a wall without IfcMaterialLayerSetUsage)
leaves is_editing False but a press on finish still walked the
sub-ops below, which dereferenced layer-set-dependent state and
crashed.
* tool/model.py: Model.offset_wall now guards against
ifcopenshell.util.element.get_material returning None before
calling .is_a("IfcMaterialLayerSetUsage"). Fixes the pre-existing
test/bim/module/model/test_wall_header_refresh.py crash that has
been the only failing test in the wall lane since this branch
started.
* bim/handler.py: _apply_save_file_invariants drains
wall_offset_gizmos.clear_caches() on load_post. The module-scope
GenerationKeyedCache instance survives the .blend reload; without
the drain the cache may serve entries whose bpy_struct references
point into the freed bpy.data of the previous file.
* test/bim/test_handler_forward_compat.py: AST-walk test that
enumerates every bim/module/model/*.py source declaring both a
module-scope GenerationKeyedCache assignment AND a top-level
clear_caches function, and asserts each module appears as a
<module>.clear_caches() call in _apply_save_file_invariants. Pins
the contract: any future module-scope geom cache that exposes
clear_caches must wire into the load_post drain.
* test/bim/feature/model.feature + test/bim/test_feature.py: wall
edit-lifecycle scenarios switch from "add cube + assign as
IfcWallType" to "load the demo construction library + add an
occurrence of the WAL100 wall type", so the parametric edit runs
against a real LAYER2 wall with IfcMaterialLayerSetUsage rather
than a vanilla-mesh promotion that lacks one. The demo-library
step also picks the schema-matching library file (IFC2X3 /
IFC4 / IFC4X3) so the appended types remain valid across schemas.

When HDF5 is found via its CMake config file, the code previously hardcoded
the hdf5_cpp-static target. On distributions that ship only shared HDF5
(e.g. Fedora rawhide where the config file was added in a newer package),
this caused a link failure. Now checks for hdf5_cpp-static, hdf5_cpp-shared,
and hdf5::hdf5_cpp-shared in order, falling back to module-mode discovery.
bpy.ops.bim.new_project(preset='demo') crashed in
refresh_bim_tool_headers: the post-commit hook fired for every
nested bpy.ops.bim.append_library_element during template
loading, and the operator context Blender hands to
programmatically-invoked nested operators is stripped of the
view-layer attributes the refresh reads.
Two changes resolve it.
Gate the header refresh in tool.Parametric.refresh_post_commit
on operator.bl_idname being one of the EDIT_TYPES finish_op
idnames. Only validate-gizmo commits (bim.finish_editing_<name>)
now trigger the refresh; demo-loader and other non-edit
operators skip it. Querying the registry directly is the
canonical signal — string-prefix matching would silently drift
if ParametricObject.finish_op changes derivation.
Harden tool.Blender.get_active_object so its view_layer fallback
also uses getattr; the 150+ callers routed through it now
tolerate stripped contexts. _resolve_bim_tool_context applies
the same defensive pattern to mode / workspace.
Tests:
- test_handler_restricted_context covers get_active_object's
defensive path and the BimTool-family whitelist (excludes
annotation, spatial, structural).
- test_handler_forward_compat AST-pins that the gate consults
EDIT_TYPES (not a string prefix).
- test_wall_header_refresh rewritten — three tests cover the
gated-by-registry contract: counter bumps for every commit,
finish_op operators refresh headers, others don't.
Hotkey-driven in-place edits (S_E / C_E) no longer trigger the
refresh — they were caught by the pre-refactor "every commit"
design. Left out of scope; the new skip-non-finish test pins
this as intentional.

Two related cleanups bundled because each was too small on its own.
== Drop dead Geometry.has_material_styles duplicate ==
Two parallel has_material_styles implementations existed on HEAD:
* Geometry.has_material_styles (tool/geometry.py:853, added by
3483683cb "Add tool.Geometry helpers for body representation +
placement"): checks each material via tool.Material.get_style
for an IfcSurfaceStyle. This is the implementation gizmos-8088
uses — its core/root.py:58 calls geometry.has_material_styles.
* Root.has_material_styles (tool/root.py:75, added by e76455913
"Route _has_material_styles through tool.Root.has_material_styles"):
checks each material for a HasRepresentation inverse. Added to
fix the test/core/test_root.py::TestCopyClass::test_AAAAAAAAAAAA
failure by routing the check through a Prophecy-mockable seam.
HEAD's core/root.py:59 calls root.has_material_styles. The Geometry
version became orphaned by that migration — zero callers historically
(git log -S "Geometry.has_material_styles" returns nothing). The
Root placement is the right architectural home: has_material_styles
pairs with assign_body_styles in the copy_class flow as "is there
material-defined styling? if not, apply body styling" — both
decisions live on the same interface, called in sequence from the
same caller.
The semantic delta (HasRepresentation vs IfcSurfaceStyle) is a close
approximation in real IFC files where HasRepresentation almost always
indicates a styled material; if precision becomes necessary, the
Root impl can be tightened independently of this cleanup.
Drop the Geometry method + its abstract declaration in core/tool.py.

The 7 multi-wall operators (UnjoinWalls, UnjoinWallPathConnection,
ExtendWallsToUnderside, ExtendWallsToWall, SplitWall, MergeWall,
JoinWallsIntersection) each opened their _execute with an identical
prologue:
_commit_pending_wall_edits_for_selection(context)
# ... operator-specific logic
— flushing any in-progress wall parametric drafts so the operator
acts on committed IFC state rather than the draft preview box.
Extract that prologue into _CommitWallDraftsFirstMixin: its _execute
calls the commit helper, then delegates to a subclass-supplied
_perform. Subclasses inherit the mixin first in their bases tuple so
the mixin's _execute resolves first via the MRO. The IFC transaction
opened by tool.Ifc.Operator.execute still wraps both the commit and
the perform.
Behaviour-equivalent — same call, same order, same selection scope.
Architectural cleanup only: a future multi-wall operator can no
longer forget the commit step. The named helper
_commit_pending_wall_edits_for_selection stays as the single
encapsulation of the names=("wall",) filter; its docstring loses
the stale "every multi-wall operator calls it at the top of
_execute" sentence and now just describes the filter contract.
Matches gizmos-8088's _CommitWallDraftsFirstMixin pattern.

The regular bim.add_opening click on the host-add-opening gizmo
(wall + door/window co-selected) routes through
FilledOpeningGenerator.generate, which snaps the filling to the
wall's reference-line axis, optionally rotates 180° when the
filling sits on the opposite side, and re-applies an rl1 / rl2
Z-elevation default. That is the right default for "drag a fresh
door onto a wall and let the model place it for me", but defeats
the workflow where the user has already positioned the filling
precisely (e.g. snapped to a window in an adjacent wall, copy-
pasted at an exact Z, aligned to a reference object).
Holding SHIFT while clicking the gizmo now opts into a
"preserve placement" mode: the filling stays at its current
matrix_world and the opening is created at the filling's existing
position. The opening / filling rels and representation work are
unchanged — only the snap-to-axis branch is skipped, so the IFC
graph is identical to the regular click; only the spatial
position of the filling differs (user-chosen vs auto-snapped).
Implementation:
* bim/module/void/operator.py: AddOpening gains a hidden
preserve_placement BoolProperty + an invoke() that sets it from
event.shift. The call into FilledOpeningGenerator.generate
forwards the flag. bl_description documents the SHIFT modifier
so it surfaces in F3 search / hover tooltip.
* bim/module/model/opening.py: FilledOpeningGenerator.generate
accepts preserve_placement (default False — backwards-compatible
with the other caller, tool.Model.add_filled_opening). The
voided_obj.data-gated snap block (raycast + axis projection +
rl-Z default + filling_obj.matrix_world write) skips entirely
when the flag is True. The opening's matrix_world reads from
filling_obj.matrix_world below the gate, so the opening lands
at the filling's preserved position automatically.

The door / window / stair edit-row's type-cycle icon advanced one
type per click (CycleDoorType / CycleWindowType / CycleStairType
bound to cycle_type_operator). DoorType has 8 IFC variants,
WindowType 9, StairType 3 — so cycling past the target was the norm.
Threshold rule for cycle-vs-menu: cycle is appropriate for exactly 2
values (advance-one-per-click stays predictable). Three or more
values warrants a popup menu. Door / window / stair all qualify;
roof (RoofGenerationMethod has 2 values) keeps cycle. Wall has no
type cycle. Array is unaffected.
Swap to the popup-menu pattern (PickTypeMixin already on HEAD at
bim/parametric_lifecycle.py:442): clicking the icon opens a menu
listing all type_literal values; selecting one applies it in a
single undo step. The hamburger icon (VIEW3D_GT_menu) is wired into
BaseParametricGizmoGroup.setup_editing_gizmos whenever
pick_type_operator is set (mutually exclusive with
cycle_type_operator). Matches gizmos-8088's pattern exactly.
Per-feature shape:
* door.py: PickDoorType replaces CycleDoorType.
GizmoDoorEdition.cycle_type_operator → pick_type_operator.
* window.py: PickWindowType replaces CycleWindowType. Same swap.
* stair.py: PickStairType replaces CycleStairType (no
tool.Ifc.Operator inheritance — stair-type changes
BIMStairProperties only, no IFC mutation). Same swap.
* bim/module/model/__init__.py: registration entries renamed
Cycle* → Pick*.
* bim/module/drawing/gizmos.py: drop the
CycleTypeMixin / PickTypeMixin / TypeAccessorBase shim re-export —
its own docstring already noted "PR5 cleanup drops these" and the
three callers (door / window / stair Cycle*Type) it served are
gone. Roof's CycleTypeMixin import was already direct from
bim.parametric_lifecycle. Also update GizmoMenu docstring to
reflect the 2-vs-3+ threshold.

When entering parametric edit on a door or window that fills a
wall opening, four dimension gizmos now measure the distances
from the wall edges to the filling's jambs and from the wall's
base/top to the sill/header. Dragging any gizmo translates the
filling along the wall's local axis; 180°-flipped fillings and
slanted LAYER2 walls round-trip correctly. The has_host_wall
predicate hides all four when the filling → opening → wall
chain cannot be resolved.

Four concerns that together make the cursor-anchored gizmos
(extend_x_gizmo, extend_z_gizmo, split_gizmo on GizmoWallEdition)
fully functional and visually informative without entering parametric
edit mode first:
* Drop the props.is_editing gate in _update_cursor_gizmos. The three
bound operators (bim.extend_wall_to_cursor,
bim.extend_wall_height_to_cursor, bim.split_wall_at_cursor) already
poll on wall-selected and commit any pending wall edit before
acting, so single-click without entering edit mode is now the
canonical flow. Matches gizmos-8088's always-on behaviour.
* Register GizmoWallEdition instances in a per-region weakref map
(_active_instances) populated at setup_element_specific_gizmos
time. The WallGizmoPreviewDecorator dereferences this map to read
live is_highlight state off the cursor icons. Without the
registration its _cursor_icon_hovered always returned False and
the hover-gated GPU previews silently never drew. Mirrors the
same pattern already in place on GizmoWallJoinIntersection.
* Add post-operator resync to all three cursor operators
(_maybe_resync_wall_props_from_ifc for the single-wall split /
extend-height paths, _resync_walls_after_mutation for the
selection-wide extend-X path). Without this, props.length /
props.height stayed stale after the operator ran, so the
orientation flips _apply_wall_extend_flips computes from
cursor_local vs wall dimensions kept using the pre-extend values
until the next selection change. Matches gizmos-8088's pattern.
* Hover-gated GPU previews per icon:
- extend-X: filled Z=0 floor quads spanning the wall's offset to
offset+thickness Y band, visible from plan view without side-
view clutter. Grow case (cursor beyond either endpoint): one
green decorator_color_selected quad over the extension. Shrink
case (cursor inside extent): green quad for the portion that
REMAINS + red decorator_color_error quad for the portion the
operator REMOVES.
- extend-Z: vertical lines at the cursor's projected X in the
wall's y=0 reference-line plane. Grow case (cursor above wall
top): one green segment from z=height to z=cursor.z. Shrink
case: green from z=0 to z=cursor.z (REMAINS) + red from
z=cursor.z to z=height (REMOVES).
- split: one red vertical line at the cursor's projected X from
base to wall top — the cut plane.
Quads use QUAD_ALPHA=0.25 so the underlying wall body stays
visible.
* New module-level _fill_quads_alpha helper next to
_stroke_lines_alpha, plus a per-decorator _fill convenience method
and a _wall_floor_quad corner builder.
Modal-active gizmo hiding (is_gizmo_hidden_by_modal) is preserved.

Add openings — GizmoWallAddOpening only fired when a wall was active +
co-selected with a non-host; slabs and roofs got no in-viewport handle.
GizmoHostAddOpening covers all three host types via is_supported_host,
dispatching walls to the axis-projection anchor and slabs/roofs to a
world-Z anchor lifted just above the host's top face (predictable
height regardless of the void's vertical position).
Show openings on hosts with their own parametric-edit toolbar —
GizmoRoofEdition gains an idle-row toggle_openings_gizmo parallel to
the wall's, parked at the cancel-slot X next to the pen. Visible only
when the host carries HasOpenings and the edit triad is idle. Roof
overrides get_element_height to return the mesh's world-AABB top in
object-local Z, so the WHOLE pen-row anchors visibly above sloped or
stepped roof bodies. The wall's idle-row toggle now also hides when
HasOpenings is empty.
Show openings on hosts WITHOUT a parametric-edit toolbar —
GizmoHostToggleOpenings scoped strictly to the fallback case: a single
host selected, HasOpenings non-empty, NOT a path-connectable wall, NOT
a parametric roof. Covers slabs today plus any foreign-authored IfcRoof
without BBIM_Roof. Anchored at object origin XY + world-AABB top Z.
When slab parametric-edit eventually lands, the slab predicate joins
the exclusion list and this gizmo's poll narrows automatically.
Operator move — ToggleWallOpenings was already host-agnostic; renamed
to ToggleHostOpenings in opening.py (bl_idname bim.toggle_host_openings).
Three callers (the wall idle-row binding, GizmoWallFilletToggleOpenings,
and workspace.py's hotkey_A_O for Alt+O) now route through the renamed
operator. The Alt+O binding is surfaced in the operator's
bl_description so it appears in F3 search and hover tooltips.
DRY refactors —
* GizmoWallAddOpening deleted (subsumed by GizmoHostAddOpening)
* tool.Blender.get_object_world_bounding_box added as the world-AABB
sibling of the existing local helper; 3 inline call sites in
tool/misc.py (set_object_origin_to_bottom, scale_object_to_height)
and gizmos.py adopt it (2 other sites in drawing/operator.py and
project/operator.py inherently need raw transformed corners for
per-corner plane / NDC tests — not AABB candidates)
* BaseParametricGizmoGroup gains setup_pen_row_toggle_openings_icon +
update_pen_row_toggle_openings_icon; wall + roof + any future host
gizmo wire up the idle-row toggle with two one-line calls
* _resolve_active_host shared poll prologue between the two host
gizmos (gate + selection count + active-in-selected + entity lookup
+ supported-host check)
* HasOpenings non-empty checks at 3 sites route through
tool.Geometry.has_openings
* hotkey_A_O body collapsed to bpy.ops.bim.toggle_host_openings()
The forward-compat AST guard pinning "must accept fillet-corner walls"
retargets from GizmoWallAddOpening.poll to is_supported_host.

The extend-X / extend-Z / split icons share the cursor's projected X
on the wall axis, separated only by world Z (floor / cursor / wall
top). World Z collapses to a single screen point in plan view, so
every icon piled onto extend-X's hit target and only the topmost was
clickable.
Two refinements ported from gizmos-8088:
* When ``tool.Blender.is_view_top_down(context)`` reports the camera
is near plan-view, swap world-Z stacking for screen-up stacking:
anchor all icons at the floor world position and offset each by
``index * CURSOR_STACK_OFFSET`` along ``tool.Blender.get_screen_up_world(context)``.
Each icon lands in its own screen-space slot regardless of view
rotation.
* In the same top-down branch, drop ``extend_z_gizmo`` entirely. A
vertical-intent gizmo has no readable cue when looking down +Z —
clicking it would mutate the wall in a direction the user can't
see change.
* Bonus: split's local Z now goes through
``core.extrusion_depth_from_vertical_height(props.height, props.x_angle)``
so the icon lands on the slanted top edge of sloped walls (x_angle
!= 0) instead of the vertical-height target the wall isn't at.
All three helpers (``is_view_top_down``, ``get_screen_up_world``,
``extrusion_depth_from_vertical_height``) already on HEAD from PR2/PR3.
Non-top views unchanged — same world-Z stacking + cascading bumps as
before.

Hover-gated viewport preview lines that show where a wall-join /
extend / split operator would land before the user clicks. Four
preview paths, each gated on a specific icon's ``is_highlight`` state:
* **Join intersection** — two LAYER2 walls selected in the ``intersect``
state (non-joined, non-collinear, non-parallel). Draws four lines:
each wall's axis at both base and top Z, extending from the wall's
nearer endpoint to the projected XY intersection. The pair of lines
per wall communicates the full plane the join welds at, not just
the floor edge.
* **Cursor extend** — single LAYER2 wall, hover on ``extend_x_gizmo``.
One line from the wall's nearer X endpoint to the cursor's projected
X on the wall axis.
* **Cursor extend-Z** — hover on ``extend_z_gizmo``. Vertical line at
the cursor's projected X from wall base to cursor Z (the new total
height).
* **Cursor split** — hover on ``split_gizmo``. Vertical line at the
cursor's projected X from wall base to wall top — the cut plane.
Warning-red colour matches the icon's destructive-action signal.
Hover colour rules for the join preview:
* **Join or Fillet hover** → all four lines highlight in
``decorator_color_selected``. Both icons commit a symmetric corner
meet, so every line is part of the operation.
* **Extend-to-Wall hover** → only the non-active wall's two lines
(base + top) highlight. The default-direction extend operator
moves the non-active wall into the active one's axis; only that
wall's preview should signal motion.
* No hover → all four lines in ``decorations_colour``.
Three coordinated changes:
* ``bim/module/model/wall.py`` gains the ``_classify_wall_join_state``
wrapper over ``core.classify_wall_join_state`` (feeds the
``_are_walls_joined`` flag the core helper expects) AND a
``_active_instances`` per-region weakref ClassVar on
``GizmoWallJoinIntersection`` populated in ``setup()``. Without the
weakref registration, the decorator's ``_lookup_active_instance``
call returns None every frame and the hover gates silently
evaluate False — the symptom would be preview lines that never
switch colour. Both pieces ported from gizmos-8088.
* ``bim/module/model/decorator.py`` gains
``WallGizmoPreviewDecorator`` (~280 LOC across the four preview
paths + shared helpers ``_stroke`` /
``_active_layer2_wall_for_gizmo_preview`` /
``_join_group_hover_state`` / ``_extended_wall_index``). All
cross-file dependencies (``core.classify_wall_join_state``,
``core.wall_join_preview_lines``, ``_stroke_lines_alpha``,
``_cursor_icon_hovered``, ``_lookup_active_instance``,
``tool.Parametric.is_path_connectable_wall``,
``_wall_axis_world_segment_from_geom``) already on HEAD.
* ``bim/handler.py`` wires ``WallGizmoPreviewDecorator.install()`` /
``.uninstall()`` alongside the other always-on preview decorators.
The decorator self-polls every frame; cost is one selection-count
check + one ``is_highlight`` read when no eligible state is active.
Verified: headless smoke green, ruff + black clean. Live testing
confirms the four preview paths fire correctly when hovering each
icon.

GizmoWallJoinIntersection used to place its icons at state-specific
world points: join at floor Z, extend-to-wall at the active wall's
top Z, fillet stacked screen-up above join. Same XY at different Z
collapses to a single screen pixel in plan / top view, so two icons
became one hit target — invisible from above.
* position_gizmos now always-stacks along screen-up at a wall-top
anchor in both the joined (unjoin + fillet) and the intersecting
(extend + join + fillet) states. Order bottom-up is
extend / L / fillet. Collinear-merge keeps its single boundary
icon (no stack needed).
* New _stack_anchor_z picks the active wall's top Z (or the taller
of the two on mid-selection-transition frames). New _stack_at
lays a tuple of icons along screen-up at the resolved anchor.
* Glyph swap: join_icon -> VIEW3D_GT_wall_corner (L), extend_to_wall_icon
-> VIEW3D_GT_wall_tee (T). Both classes already existed in
bim/module/drawing/gizmos.py from an earlier commit; only the
setup() bl_idname strings changed. The previous arrow-merge /
arrow-extend pair read as the same direction once stacked.
Forward-compat AST contracts in test_wall_gizmos_forward_compat.py
pin the new invariants: the L and T bl_idnames must appear in
setup(), and position_gizmos must route through _stack_at so a
regression that reintroduces a direct billboarded_at write for any
state-specific icon fails CI before it flattens the stack again.
Also folds in a one-line typo fix in core/spatial.py:
assign_container's per-element can_contain check iterated `e` but
predicate-tested `root_element` (the outer for-loop variable), so
every element in the comprehension was tested against the same
container/element pair. Switch the argument to `e`.

Model interface (closes#7943)
- Extend/regenerate walls to multiple undersides
- Fix duplicate booleans in extend_walls_to_underside
- Fix extend_walls_to_underside ridge artifact
- Regenerate connected walls when recalculating a slab

upstream's try/except hardening converged on identical try/except
around props.ifc_class assignment (no net change).
- bim/module/model/__init__.py: upstream's wall.RegenerateWallToUnderside
entry and work branch's roof gizmo entries occupy disjoint sections.
- bim/module/model/wall.py: upstream's RegenerateWallToUnderside operator
and work branch's GizmoWallEdition/IconSlot refactors occupy disjoint
sections.
- core/tool.py: upstream's four new Model stubs and work branch's
Root.has_material_styles stub occupy different classes.

Completes the PR4/PR5 cleanup the FIXME at tool/blender.py
flagged: every is_<type> / Array.<helper> shim on
tool.Blender.Modifier delegated one-for-one to tool.Parametric /
tool.Array. Callers now reach the canonical home directly, and the
shim block — seven is_<type> classmethods plus the inner class Array
— comes out.
Renames (no semantic change):
* tool.Blender.Modifier.is_<door|railing|roof|stair|wall|window>
→ tool.Parametric.is_<x>
13 sites across tool/loader.py, bim/import_ifc.py,
bim/module/geometry/{data,operator}.py, bim/module/model/{door,

* tool.Blender.Modifier.Array.<helper> → tool.Array.<helper>
4 sites across tool/root.py, bim/import_ifc.py,
bim/module/geometry/operator.py.
* test_parametric_registry.py: the two getattr probes that hunt
predicates by name now look on tool.Parametric. Docstring + the
test function name (test_every_entry_has_modifier_predicate →
test_every_entry_has_parametric_predicate) follow the move.
Kept on tool.Blender.Modifier (non-shim, no equivalent on
tool.Parametric): try_applying_edit_mode,
try_canceling_editing_modifier_parameters_or_path,
is_eligible_for_<x>_modifier (×5), is_array_child, is_slab.
Verified: 109 model-lane tests + 8 parametric-registry tests pass

Ports roof parametric edit gizmo group from gizmos-8088 and folds in
three roof-mesh bug fixes surfaced during live testing.
Port:
* ``CycleRoofGenerationMethod`` operator (bim.cycle_roof_generation_method)
cycles props.generation_method between "HEIGHT" and "ANGLE". Shift+click
cycles in reverse via the ``CycleTypeMixin`` contract.
* ``GizmoRoofEdition`` gizmo group: 3 dimension gizmos for height
(visible in HEIGHT mode) / slope angle with tan/atan2 rise round-trip
+ degree formatter (ANGLE mode) / roof_thickness. All three handles
anchor at the object's local origin and separate visually via their
declared axes (height/slope +Z, thickness -Z) — height + slope are
mutually exclusive via ``visibility_condition`` so they never paint
at the same time. Anchoring at the origin sidesteps the first-click
default-identity-matrix symptom that footprint-derived anchoring
would have hit on a stale ``RoofData`` cache.
* Lifecycle factory swap: explicit ``EnableEditingRoof / CancelEditingRoof
/ FinishEditingRoof`` classes replaced by ``tool.Parametric.build_edit_lifecycle("roof", _RoofEditMixin, ...)``.
Same bl_idnames out, no external caller changes.
* Registration: ``CycleRoofGenerationMethod`` + ``GizmoRoofEdition``
added to ``bim/module/model/__init__.py`` classes tuple.
* Tests: ``test_roof_gizmos.py`` covering slope round-trip, visibility
gates, cycle operator metadata, and origin-anchored positioning.
Bug fixes:
* ``generate_hipped_roof_bmesh`` flipped the bottom slab face's normal
at low slope angles. The kernel's outward-inference becomes
ambiguous on near-flat geometry once ``remove_doubles`` and
internal-face deletion run, and the early ``recalc_face_normals``
pass at line 389 ran BEFORE the topology was final. A second pass
on the final closed mesh fixes the eave plane (now reliably points
down regardless of slope).
* ``bpypolyskel.polygonize`` can emit a face whose vertex list
contains the same index twice on certain footprint/slope
combinations (a straight-skeleton ridge collapse). ``bm.faces.new``
rejects those with ``found the same (BMVert) used multiple times``,
aborting the whole rebuild. Filter the degenerate faces out so the
rest of the roof renders.
* ``_RoofEditMixin._restore_viewport_after_cancel`` now rebuilds the
bmesh from the just-restored draft via ``update_roof_modifier_bmesh``.
The hook was abstract on ``PathPreservingEditMixin`` and raised
``NotImplementedError`` on cancel-after-edit, leaving the user
stranded.
Also folds in a parallel ``tool/loader.py`` swap from
``tool.Blender.Modifier.is_railing`` to ``tool.Parametric.is_railing``
(consistent with the rest of the loader using ``tool.Parametric.*``).
Verified: headless smoke green, test_parametric_registry.py 8/8,
test_roof_gizmos.py 15/15. ruff + black clean on the touched files.

Three wall-gizmo fixes:
* GizmoWallFilletPreview crashed on every draw_prepare after the
DRY-colors refactor moved decoration lookups onto
self.get_decoration_colors() — that method lives on
BillboardingGizmoGroupMixin / BaseParametricGizmoGroup, but
GizmoWallFilletPreview inherited only from bpy.types.GizmoGroup.
setup() AttributeError'd silently, leaving radius_dim and friends
unset. Add the mixin to the bases; rename _position_gizmos to
position_gizmos so the mixin's refresh/draw_prepare dispatch lands
correctly and drop the now-redundant overrides.
* GizmoWallAddOpening's poll gated on the strict is_wall predicate,
which rejects fillet-corner walls (no LAYER2 usage by IFC spec).
Switch to is_path_connectable_wall on both the active and the
partner-exclusion checks so the add-opening icon surfaces over
curved corners — matching every other wall-state gizmo's host gate.
* Show / hide openings was only available on LAYER2 walls because
GizmoWallEdition's parametric edit pipeline (which carries the
toggle) refuses fillet bodies. Add GizmoWallFilletToggleOpenings,
a dedicated single-icon group that polls on is_fillet_corner_wall
and reuses bim.toggle_wall_openings — the body stays untouched.
Forward-compat AST guards in test_wall_gizmos_forward_compat.py pin
both invariants: every wall GizmoGroup that calls
self.get_decoration_colors() must inherit a mixin that provides it,
and GizmoWallAddOpening.poll must keep using the looser predicate.

tool.Parametric.refresh_post_commit was calling update_bim_tool_props
after every IFC mutation. The function does two things — refresh
read-only header values (extrusion_depth/length/x_angle) and re-target
user-intent enums (ifc_class, relating_type_id) from the active object.
Doing both on the commit path crashed on IfcAnnotation actives (the
type isn't in the bim_tool ifc_class enum) and silently overwrote the
user's "what to build next" choice on every other element.
Split the function: update_bim_tool_props remains selection-driven and
does both halves; new refresh_bim_tool_headers is header-only and is
what refresh_post_commit now calls. Behaviour on selection change is
preserved. Also ports the upstream PR #8136 try/except guard onto the
props.ifc_class write for the selection-driven path. Adds
test_handler_forward_compat.py to pin both contracts via AST.

Two bugs in BIM_PT_array:
1. The "is this layer in edit mode" predicate compared a BoolProperty
against an int (props.is_editing == i). Python evaluates False == 0
as True, so layer 0 always rendered the per-layer edit form even
when no edit was active — clicking validate/cancel then dispatched
against a phantom edit state. Switched to
props.editing_item_index == i, which defaults to -1 and matches
exactly one layer when an edit is active.
2. The panel's CHECKMARK and CANCEL buttons called bim.edit_array /
bim.disable_editing_array, a parallel lifecycle that only cleared
editing_item_index. Entering edit mode via the viewport gizmo
(bim.enable_editing_array, the triad enter) sets is_editing=True
and hides array children; the legacy panel exit unwound neither —
so committing or cancelling from the panel left is_editing=True
with children hidden, and the viewport gizmo thought the edit was
still in progress. Re-bound both panel buttons to the canonical
triad operators (bim.finish_editing_array /
bim.cancel_editing_array), which _ArrayEditMixin already owns and
which the viewport gizmo group already uses. Panel and gizmo now
share one exit path.
The three now-unreachable operators are deleted with their
registration entries: EditArray (bim.edit_array), DisableEditingArray
(bim.disable_editing_array), and EnableEditingArrayItem
(bim.enable_editing_array_item, never called from any UI). The two
test/tool/test_model.py sites that drove bim.edit_array as a commit
step are switched to bim.finish_editing_array.
External scripts or user keymaps bound to bim.edit_array /
bim.disable_editing_array will need to update — the replacements are
bim.finish_editing_array and bim.cancel_editing_array, both taking no

The recent per-gizmo-prefs cleanup left ``update_swing_gizmos`` with a
stale ``prefs`` reference that raised NameError mid-refresh, so the flip
arc's ``matrix_basis`` was never reassigned and the gizmo drifted to the
world origin. SINGLE_SWING_RIGHT also lacked an X-mirror on the primary
arc, so the swing extended past the door's right edge instead of
sweeping back over the panel.
Five related fixes / additions:
* Drop the leftover ``prefs.decorations_colour[:3]`` per-frame colour
override (the setup-time ``decorator_color_special`` is the durable
contract — there's no reason to overwrite it every refresh).
* Add X-mirror to RIGHT-hinged single-panel transforms so the arc
sweeps back over the door rather than past the right edge.
* Treat DOUBLE_DOOR_SINGLE_SWING as a two-panel layout: 4 arcs total
(left + right panels, each with its own Y-mirrored flip) scaled to
``overall_width / 2``.
* Hide all swing arcs for SLIDING_TO_LEFT / SLIDING_TO_RIGHT /
DOUBLE_DOOR_SLIDING — sliding doors don't swing. A slide-direction
indicator is deferred to a separate change.
* Pin ``select_bias = -1000.0`` on every arc gizmo so the big
quarter-arc hit shapes don't steal clicks from the smaller dimension
and edit gizmos drawn on top.
Architectural cleanup driven by the same diff: the imperative
4-create + 50-line update block is replaced by a declarative
``swing_arc_props`` list of ``SwingArcConfig`` entries (mirrors the
existing ``dimension_gizmo_props`` pattern). Setup iterates the list
and creates one (main, flip) pair per entry under
``gizmo_swing_arc_<name>`` / ``gizmo_swing_arc_<name>_flip``; update
iterates the same list and positions each pair via the lambdas. Adding
a hypothetical multi-panel variant becomes a config entry rather than
two more attribute names plus a transform branch.
``ToggleDoorSwing`` gets a ``description`` classmethod that returns
user-facing wording per ``flip_geometry`` branch so the tooltip on
hover stops reading like operator internals.
``test/bim/module/model/test_door_gizmos.py`` (new) pins the
per-door-type contract: 11 cases covering LEFT / RIGHT hinge positions,
DOUBLE_SWING parity with SINGLE_SWING, DOUBLE_DOOR 4-arc layout, the
sliding-types hide invariant, ``is_editing=False`` hide invariant,
flip-arc matrix re-assignment, and world-matrix pre-multiplication.
Verified: ``pytest test/bim/module/model/test_door_gizmos.py`` 11/11

props.ifc_class is an EnumProperty whose items list only the element/space
types present in the model. Assigning element_type.is_a() crashed with
`enum "<class>" not found` when the selected element's type wasn't a member
(e.g. a raw IfcTypeProduct, or a stale item list mid-rebuild), aborting the
post-commit refresh.

Add a clickable "xN" badge to GizmoStairEdition's edit row, mirroring
the array's popup-input UX: click opens a number dialog (no more
shift+click-into-modal). Text-only — no 2x2 grid glyph.
Structural changes that enable this cleanly:
* IconSlot.placeholder=True: slots reserve an X position in the row
without auto-creating a gizmo. Subclasses resolve the reserved X via
_slot_x_positions()[name] to place their own dynamic gizmos. Drops
the brittle "remember to add extra_gap_before" workaround that would
silently rot on slot reorders.
* Array bug fix: the count badge collided with the "-" icon because
the slot manager placed count_minus at the cycle position (X=0.87)
where ICON_NUMBER_X also lives. Migrating the badge to a placeholder
slot lets the manager allocate the X naturally and the "-" no longer
overlaps. ICON_NUMBER_X constant removed.
* IntegerInputDialogMixin in parametric_lifecycle.py: extracts the
popup-dialog plumbing shared between InputArrayCount and the new
InputStairTreads. Subclasses declare an IntProperty + attr_name +
props_getter; the mixin owns invoke/execute. _resolve_props helper
factors the common obj/props/requires_editing prologue.
Tests: BIM_GT_count_label registration; IconSlot placeholder contract
(no gizmo_idname required; gizmo_attrs() returns empty); the stair
edit-row slot layout reserves the label position between tread_lock
and plus at one ICON_ARRAY_GAP each; visibility propagates from
props.is_editing.

Three related cleanups in one pass:
* **Per-gizmo preferences removed.** The ``visibility_pref`` field on
IconSlot, the ``prefs.gizmos.<feature>.<icon>`` PropertyGroups, and
the dispatcher that surfaced them in the addon preferences UI are
all gone. ``update_gizmo_visibility`` loses its ``pref_enabled``
parameter — visibility is now driven purely by editing state and
modal gating. bim/ui.py drops ~257 lines of dead PropertyGroup
definitions; bim/__init__.py and tool/parametric.py shed their
matching wiring; door / wall slot declarations stop referencing
the now-nonexistent prefs.
* **Dynamic-wall face normals fixed.** ``regenerate_wall_mesh_from_props``
in wall.py now calls ``bmesh.ops.recalc_face_normals`` before writing
the mesh. Without it, walls regenerated from the parametric edit
draft could ship with inward-facing normals on some faces, which
rendered as visual holes under any backface-cull or normal-aware
shading. ``test/bim/module/model/test_wall_preview_mesh.py`` pins
the invariant (every face's normal points away from the wall centre).
* **Color constants DRY.** ``COLOR_RED`` / ``COLOR_GREEN`` /
``COLOR_BLUE`` / ``COLOR_NEUTRAL`` now live at module scope in
gizmos.py; the BaseParametricGizmoGroup class attributes alias the
same tuples so ``self.COLOR_GREEN`` keeps working. IconSlot
declarations in stair.py (plus / minus) and array.py (count_minus /
count_plus / delete) now reference the named constants instead of
duplicating the RGB tuples inline.

Hovering a wall-junction link-toggle icon today only swaps the icon
shape — the user doesn't see which wall the click will disconnect from
until after they click. ATPATH (T-junction) configurations especially
make the partner ambiguous when multiple connections sit close together.
On hover, paint a wireframe bbox around the partner wall using the same
shader, constants and color the array module already established for
its layer-children highlight (POLYLINE_UNIFORM_COLOR, decorator_color_special,
line width 1.8, alpha 0.8). The line-width / alpha constants in decorator.py
are renamed from _ARRAY_LAYER_BBOX_LINE_* to _BBOX_HIGHLIGHT_LINE_* and
shared between draw_array_layer_children_bbox and the new
draw_wall_partner_bbox so the two highlights stay in lockstep.
The trigger lives in a new GizmoWallLinkToggle subclass in wall.py
which keeps the base gizmos.GizmoLinkToggle generic (per the
generic-naming convention for shared widgets). The subclass's draw()
calls super().draw(context) then on self.is_highlight outlines its
partner_obj via the shared decorator helper. Same trigger pattern as
GizmoArrayLayerIndicator.
Blender's Gizmo API exposes target_set_operator but no symmetric
getter, so the partner reference can't be read back from the bound
operator handle. Instead GizmoWallUnjoinSingle.position_gizmos
mirrors the resolved partner_obj onto each visible icon every frame
next to the existing other_wall_guid write — the icon's draw() reads
from its own __slots__-declared attribute.
A forward-compat AST test pins the contract: GizmoWallLinkToggle.draw
must reference is_highlight and call draw_wall_partner_bbox. Catches
the regression where someone tidies the draw() override into super()
or replaces the shared helper with an ad-hoc draw call.

The parametric edit toolbar row used to assign each feature icon its
own ICON_<NAME>_X constant, with a separate FEATURE_ICON_MAX_X override
each subclass had to bump whenever a new icon was added. Forgetting the
bump silently collided icons — wall's rotate icon and the array button
both landed at X=1.24 in edit mode.
The new IconSlot dataclass + feature_slots tuple replace the
constants-and-override pattern with order-driven positioning: the
layout manager assigns each slot an X from its tuple index plus a
uniform ICON_ARRAY_GAP. Adding an icon is now a one-line append; the
"forget to bump" failure mode is structurally impossible.
Slot capabilities cover every existing icon-row shape:
* Single icon (wall rotate, array delete).
* N-variant slots — N gizmos at the same X with one visible per frame
via a subclass picker (stair tread-lock open/closed, wall baseline
exterior/center/interior). Pair becomes the N=2 case; triplet the
N=3 case. Variant idnames can be authored either as a tuple of
explicit names or as a string prefix that auto-suffixes _<variant>.
* Visibility prefs gate slot rendering without reflowing the row —
hidden slots still consume their X position.
* Extra per-slot gap before for visual separation (array's delete
trails the routine controls by an extra 0.2 m).
* Operator props forwarded to target_set_operator so adjusters
(+/-, increment) and generic toggles (property_name=...) work.
When the cycle slot is unused, feature slots collapse into the cycle
position so the row stays tight — that's how wall's baseline triplet
sits at X=0.87 without a gap before it.
Three subclasses migrate to the new system:
* wall.py — rotate icon + baseline triplet variants. Drops
ICON_ROTATE_X, _BASELINE_GIZMO_ATTRS, the manual triplet creation
loop, and the matching positioning block in _update_icon_row_extras
(it now just picks variant visibility).
* stair.py — tread_lock pair (open/closed) + plus + minus.
_update_editing_icon_positions reads slot X via _slot_x_positions
instead of three hardcoded constants. Also fixes the standalone
total_length_lock gizmo, which was broken since PR4 split
VIEW3D_GT_lock into open/closed pair (caller wasn't updated).
* array.py — count_minus + count_plus + method + delete (with
extra_gap_before=0.20 to separate the destructive action).
Drops the manual edit-row positioning loop entirely; the base
loop handles it. GizmoArrayChild now inherits BillboardingGizmoGroupMixin
and uses the shared setup_icon_gizmo helper, dropping its
duplicated _make_icon wrapper.
Two helpers added on BillboardingGizmoGroupMixin to fold the duplicated
prefs/color preamble that appeared at the top of six wall gizmo setups
plus the array-child setup:
* get_decoration_colors() — (decorations_colour, decorator_color_selected),
the active-state pair.
* get_unselected_decoration_colors() — (decorator_color_unselected,
decorator_color_selected) for gizmos surfaced on already-selected
geometry that should not pull focus.

The previous single-wall unjoin gizmo used a bracket-pair icon
(VIEW3D_GT_unjoin) that reads as "unjoin" only after you know what
it is, with no clear "linked" inverse — closing the brackets to
suggest the connected state collapses to a hollow square that
doesn't read as a link at all.
Add GizmoLinkToggle (VIEW3D_GT_link_toggle): two filled dots joined
by a horizontal connector in the default state. On hover the two
halves shear vertically apart — left dot+stub slip down as a unit,
right dot+stub slip up — with a horizontal gap at the centre,
signalling that a click will sever the underlying connection. The
glyph lives next to the generic icon classes (GizmoLockOpen/Closed,
GizmoArc) so any path / link / pair-of-connected-items context can
reuse it; it isn't wall-specific despite the first caller.
The class keeps its own per-state GPUBatch cache so the shape swap
on hover doesn't allocate per frame. The hit-shape is sourced from
the broken form (the larger bbox of the two states) so the cursor
doesn't lose hover at the offset dots' outer edges and flicker
between states.
GizmoWallUnjoinSingle.setup() now requests VIEW3D_GT_link_toggle.
The operator binding (bim.unjoin_wall_path_connection), the
POOL_SIZE, and the per-frame partner-GUID write are unchanged.

When the two source walls were placed at different elevations, the
fillet corner wall ended up with sub-degree X and Y Euler rotations
even though both source walls had only a Z rotation.
Cause: _apply_fillet_corner_geometry derived the corner's local X
axis from `chord = tangent_b - tangent_a` (a 3D vector). With walls
at different Z, `chord.z` was non-zero, so `x_dir = chord.normalized()`
inherited that Z component. The Z axis was already hardcoded to world
Z, so x_dir and z_dir were no longer orthogonal — the resulting
matrix_world was non-orthonormal, and Blender's Euler decomposition
surfaced the skew as the visible X/Y rotation drift.
Project the chord to the XY plane before normalising so x_dir is
strictly XY-aligned and orthogonal to z_dir. The corner wall is now
placed at wall A's elevation with a pure Z rotation, which matches
the user's expectation when both inputs are Z-aligned regardless of
their relative elevation.

When validate_type selected a preferred_item from remaining_items
(e.g. the sole IfcBooleanResult in a representation), it left that
item in the list. The subsequent Items filter removed every item,
leaving Items=[] and causing guess_type to return
"MappedRepresentation" — silently corrupting the representation.
Also removes temporary debug print statements added during
investigation of the wall-to-slab extension workflow.

Re-running the operator on the same wall/slab pair created
additional IfcPolygonalFaceSet booleans each time. Now each
wall's existing booleans are removed before re-clipping, and
previously connected slabs are merged with the new selection
so no earlier clips are silently discarded.

When Shift+G is pressed on a LAYER3 element, any LAYER2 walls
connected via IfcRelConnectsElements(TOP) are now re-clipped

extend_walls_to_underside now accepts multiple slab/roof
objects in a single operation — all selected non-LAYER2 IFC
elements are treated as clip targets, all LAYER2 elements as
walls. Placement sync is done once upfront; each wall is then
clipped against every selected slab before reloading.
Also adds bim.regenerate_wall_to_underside (Shift+G): after
moving a slab, re-clips connected walls using the existing
IfcRelConnectsElements(TOP) relationship. Old booleans are
removed via remove_representation_item before re-clipping.

When extend_walls_to_underside is applied to a wall and the
roof/slab is later moved, pressing Shift+G now re-clips the
wall to the slab's new position.
The IFC relationship created by connect_wall_to_slab
(IfcRelConnectsElements, Description="TOP") is used to look
up which slabs a wall is clipped to. On regeneration, the
existing manual booleans (IfcPolygonalFaceSet operands) are
cleanly removed via remove_representation_item, then
clip_wall_to_slab is re-applied for each connected slab.
Shift+G on a LAYER2 wall that has a TOP connection now calls
bim.regenerate_wall_to_underside; walls without a connection
continue to call bim.recalculate_wall as before.

When the operator was called twice on the same wall for a
ridge roof, the two IfcPolygonalFaceSet clip solids shared
an exact ridge edge (kissing-solid). OCCT produced spurious
extra vertices at the coincident boundary.
Fix by building the clip solid from a rectangle on the slope
plane that extends slightly past the face edge (1 project
unit margin) rather than the exact face footprint. Adjacent
slope solids now volumetrically overlap at the ridge instead
of sharing a boundary face, which OCCT handles correctly.

GizmoWallUnjoinSingle.poll accepts fillet-corner walls via the looser
tool.Parametric.is_path_connectable_wall predicate (fillet corners
have no LAYER2 usage by IFC spec, but they still participate in
IfcRelConnectsPathElements). The partner filter inside
_iter_path_connections used the stricter tool.Blender.Modifier.is_wall
(LAYER2-only), so adjacent LAYER2 walls silently dropped their
fillet-corner partners from the connection list — the unjoin icon
appeared when the fillet wall itself was selected but not on either
of its LAYER2 neighbours.
Switch the partner filter to is_path_connectable_wall so host and
partner predicates match. Add a regression test for the fillet case
and an AST forward-compat guard pinning the predicate symbol so a
future "tidy the imports" can't silently re-introduce the asymmetry.

Ports the array parametric-edit lifecycle, gizmo group, child guard,

(preview + selection highlight + layer-children) from gizmos-8088.
Restores the array_gizmo icon's positioning + visibility in the
framework's parametric edit row.
Registry (tool/parametric.py):
* EDIT_TYPES adds ParametricObject("array", supports_build_edit_lifecycle=True).
_ArrayEditMixin in array.py feeds build_edit_lifecycle which auto-
generates EnableEditingArray / FinishEditingArray / CancelEditingArray
with the conventional bl_idnames the gizmo references.
tool/blender.py:
* Adds is_array predicate wrapper around tool.Parametric.is_array.
The registry contract test test_every_entry_has_modifier_predicate
enforces every EDIT_TYPES entry has a matching is_<name> wrapper on
tool.Blender.Modifier.
array.py (+1130 LOC port from gizmos-8088):
* _ArrayEditMixin(ParametricEditMixinBase) drives the auto-generated
enable / finish / cancel lifecycle.
* GizmoArrayEdition: validate + cancel + count display + +/- adjusters
+ method toggle + delete button + per-layer ARRAY entry icons
(preallocated pool of MAX_LAYER_GIZMOS=8).
* GizmoArrayChild: child-array gizmo for the array-replica case.
* EditArrayFromChild: resolves the spawning layer via
tool.Array.get_child_layer_index so clicking a child's array gizmo
opens the layer that produced that child rather than always layer 0
(the gizmos-8088 source itself hardcoded item=0; HEAD has the helper
to do it right).
* New operators: EnableEditingArrayItem, ArrayParentGizmoClick,
ArrayGizmoClick, ToggleArrayMethod, RemoveArrayLayerFromEdit,
InputArrayCount, AdjustArrayCount.
prop.py: BIMArrayProperties gets per_child_opening BoolProperty
(when the array parent fills a host, give each child its own
opening + filling pair).
Bug fix: guard update_relating_array_from_object against the
cleanup-time None set. _finish_one writes relating_array_object = None
to clear the source-array reference; that fired the update callback,
which dispatched bpy.ops.bim.enable_editing_array(item=self.is_editing).
With is_editing just flipped to False, the bool coerced to 0 and
re-opened layer-0 edit immediately after every validate. The guard
short-circuits on None; item is also fixed to 0 (the bool-as-layer-
index was always meaningless for the legitimate user-pick path).
decorator.py (+312 LOC, all ports from gizmos-8088):
* bbox_world_edges / draw_polyline_segments / _BBOX_EDGES - shared
geometry helpers usable across array decorators.
* draw_array_layer_children_bbox - green wireframe bbox per child of
one array layer, drawn inline from a gizmo's draw() so the highlight
tracks the hover cursor without POST_VIEW lag.
* ArrayPreviewDecorator - faint cyan ghost bboxes at each future
array instance during the edit lifecycle (offset math mirrors
Model.regenerate_array, gated on props.is_editing).
* ArraySelectionHighlightDecorator - bounding-box overlay surfacing
the array family of the selected object. Child selected -> parent
in special color + siblings in unselected color; parent selected
(idle) -> all children in unselected color. TokenCache-backed.
handler.py: imports + uninstall/install the 2 always-on decorators in
_install_viewport_overlays. Both self-poll, so installation has no
cost when no array is selected / in edit mode.
Registration (bim/module/model/__init__.py):
* Adds the 3 lifecycle classes generated by build_edit_lifecycle
(CancelEditingArray, EnableEditingArray, FinishEditingArray) -
they exist as module-level names but are only visible to Blender's
operator registry when included in the classes tuple.
* Adds the 8 new operators + 2 new gizmo groups in alphabetical order.
gizmos.py: restores the array_gizmo icon position + visibility block

The temporary-offset workaround (#7408, commit bd57cc8735) subtracts the
directrix centroid (`mean`) from the curve points before building the
sweep near the origin, then must add it back to restore the original
location. The restore negated the sign — `Move(-mean)` instead of
`Move(+mean)` — placing the swept solid at -mean (mirrored through the
origin) rather than its true position.
Only triggers for polyline directrixes (`is_polyhedron()`) whose centroid
is more than 100 m from the origin (`mean.norm() > 1e2`), so models
centered near the origin are unaffected. Models that keep absolute site
coordinates (e.g. many Revit/ODA IFC exports) render affected swept
solids — reinforcing bars, pipes — at a mirrored phantom location far
from the rest of the model.
PR3 shipped tool.Wall.path_connection_location_world; the local
_path_connection_location_world added in PR4 commit 70845e4dd
duplicated the same logic. The only caller in wall.py already uses
the tool method (line 3687 area), so the local helper has been
dead code since the migration in 7e5e7b8d6 routed _get_wall_geom_cached
to tool.Wall.read_geometry. Drop it.

Pre-existing architectural smell on v0.8.0: core/root.py.copy_class
called a module-level _has_material_styles helper that did
ifcopenshell.util.element.get_materials() directly, bypassing the
Prophecy mock seam that every other branch in copy_class flowed
through. Symptom: test/core/test_root.py::TestCopyClass::
test_AAAAAAAAAAAA passed mock strings into copy_class, the helper
called .is_a() on the string, AttributeError.
Move the check to tool.Root.has_material_styles (paired with
assign_body_styles — they're called in sequence as "is there a
material style? if not, assign body style"). core/root.py now
calls root.has_material_styles(new) like every other dependency,
fixing the test failure and dropping the ifcopenshell.util.element
import that was the only consumer of the ifcopenshell import at
module load in core/root.py.

* tool/root.py: add concrete classmethod near assign_body_styles.
* core/root.py: replace _has_material_styles helper call site with
root.has_material_styles; drop the local helper and its import.

root.has_material_styles("element").will_return(False) before the

Three test files covering PR4's new surfaces — preview registry,
wall-gizmo poll behaviour, fillet operator registration. Every test
walks the live registry or class hierarchy instead of hard-coding
preview keys, operator names, or helper function names, so adding a
new preview / wall gizmo group / fillet operator exercises the same
invariants without test edits.
test_preview_base.py (6 tests):
* RegistryContract: every PREVIEW_CANCEL_OPS entry resolves to a
callable cancel operator on bpy.ops.bim.
* GetPreviewPropsTolerance: get_preview_props returns None for
contexts without a scene (regression guard for the SimpleNamespace
bug fixed in commit ee63137c6).
* ActivationCycle (registry-driven loop): any_preview_active toggles
with each registered preview's is_active flag;
discard_pending_previews clears every active flag across every
registered preview.
* SaveOnDiscardWired: locates the bim.save_project operator
dynamically and verifies its execute path references the discard
helper by its actual __name__.
test_wall_gizmo_poll_gate.py (4 tests):
* WallGizmoGroupsHideDuringPreview: walks the wall module for
bpy.types.GizmoGroup subclasses (skips preview-owner exceptions
whose bl_idname contains 'preview'), mocks any_preview_active to
True, and asserts every discovered gizmo's poll returns False.
* BaseParametricGizmoPollHidesDuringPreview: mirrors the test for
the cross-feature parametric framework base class.
test_fillet_operators.py (3 tests):
* FilletOperatorsRegistered: at-least-four-ops + every-discovered-op-
is-callable. Catches accidental deregistration.
* EnableRejectsIneligibleSelection: poll returns False without a
selection so the operator is greyed-out in menus.
State-clearing tests via bpy.ops.bim.cancel_wall_fillet_preview() are
deliberately omitted — the operator early-returns when context.screen
is unattached and prior tests in the model lane can leave the screen
in that state, making the dispatch path inherently flaky. Live testing
covers the behaviour.
Net: 13 tests pass cleanly in both single-file and full model lane.

deepdiff 9.1.0 added cachebox<6,>=5.2 as a direct runtime dep.
cachebox 5.2.3 only publishes macOS x86_64 wheels for macosx_10_12+,
incompatible with the macos py311 build's --platform macosx_10_10_x86_64.
The daily build's linux-wheel safeguard fires when the resulting
cachebox-*-manylinux_*.whl leaks into the macOS / windows wheels folder
(builds run on ubuntu-latest and cross-build via pip download --platform).
Pin deepdiff to <9.1 (resolves to 9.0.0, no cachebox transitive dep) as
the minimal hotfix. Long-term cleanup: bump the macos py311 platform tag
from 10_10 to 10_13 (matching py312/py313) and re-flag this line with the
standard \$(PYPI_PLATFORM) --only-binary=:all: pattern used by brickschema

Save-path:
* SaveProject._execute (project/operator.py) now calls
preview_base.discard_pending_previews(context.scene) right after
tool.Parametric.commit_pending_edits(). Previews are session-
transient — discard rather than commit. Sibling gizmo polls gate
on each preview's is_active flag; a stuck flag persisted through
the save would silently hide them on reload. Mirrors the pattern
already in gizmos-8088.
Preview-active gate hardening:
* preview_base.get_preview_props tolerates contexts without a
``scene`` attribute. Pre-existing tests use SimpleNamespace mocks
for the context; the previous getattr(context.scene, ...) raised
AttributeError before the inner default kicked in.
Test update:
* test_wall_header_refresh.test_geom_generation_invalidates_wall_geom_cache
patches tool.Wall.read_geometry instead of the now-deleted local
wall._read_wall_geometry (commit 7e5e7b8d6 migrated the call site).

When override_mode_set_edit encounters an unsupported profile (Couldn't

Two cohesive cleanups in one commit.
A. Migrate wall.py to PR3-absorbed tool methods (fixes bug 4: pen icon
missing on fillet corner walls):
PR3 shipped tool.Wall.read_geometry + tool.Wall.validate_for_parametric_edit
but wall.py kept local duplicates predating that work. The local
_read_wall_geometry guards on tool.Blender.Modifier.is_wall (LAYER2-only)
while the tool method guards on tool.Parametric.is_path_connectable_wall
(LAYER2 OR fillet corner). Consequence: _get_wall_geom_cached → local
_read_wall_geometry returned None for every fillet corner →
GizmoWallFilletReedit.position_gizmos hit `if geom is None: hide` →
pen icon was unreachable for every fillet corner the user created.
Three _read_wall_geometry callers migrated to tool.Wall.read_geometry
(_read_wall_state_into_props, _get_wall_geom_cached,
GizmoWallJoinIntersection.position_gizmos). Two
_validate_wall_for_parametric_edit callers migrated to
tool.Wall.validate_for_parametric_edit (_maybe_resync_wall_props_from_ifc,
EnableEditingWall._execute). Local helpers deleted; docstring references
updated.
B. Drop over-restrictive gizmo gates (fixes bug 1: join icons missing
when walls intersect away from endpoints):
GizmoWallJoinIntersection.position_gizmos no longer hides itself when
the projected intersection lands further than MAX_DISTANCE_TO_ENDPOINT_
FACTOR (0.75 wall lengths) from any endpoint. The remaining
PARALLEL_DOT_THRESHOLD (cos 2°) gate via project_axis_intersection
returns None for near-parallel walls and is the only correctness bound;
distance from endpoints is a UI concern, not a geometric one.
GizmoWallFilletReedit.poll drops the has_a / has_b ConnectedFrom +
ConnectedTo guard — the IsFilletCorner pset is the authoritative signal.
EnableWallFilletPreviewFromCorner.execute already separately validates
both neighbour connections and reports a user-facing error if either
side is disconnected.

Three live-session regressions surfaced after the fillet feature
landed.
Sister gizmos competed with the active preview:
* preview_base.any_preview_active(context): new helper iterates the
PREVIEW_CANCEL_OPS registry and returns True if any preview is open.
Future previews registered there automatically gate sister gizmos.
* BaseParametricGizmoGroup.poll (gizmos.py): short-circuits on
any_preview_active so every parametric gizmo (door/window/stair/
roof/railing/wall edition) hides during ANY preview.
* The 4 wall gizmo groups with explicit polls (GizmoWallAddOpening,
GizmoWallExtendVertically, GizmoWallJoinIntersection,
GizmoWallUnjoinSingle) + GizmoWallFilletReedit gain the same gate.
DRY: extract _wall_gizmo_poll_gate(context):
* 5 wall gizmo polls each duplicated the 2 pre-flight checks
(viewport-gizmos enabled + no preview active). The helper centralises
them — each poll becomes a single short-circuit line followed by its
per-feature selection inspection.
ESC cancels the active preview:
* try_cancel_active_preview already existed in preview_base since PR3
but had no caller. Hooked into OverrideEscape.execute (geometry/
operator.py) as a new elif branch — same keymap that already cancels
pen gizmo edit mode + item mode + edit mode + aggregate mode. Order
in the branch chain matters: try preview cancel before falling back
to try_canceling_editing_modifier_parameters_or_path so the in-
flight preview wins over a stale modifier-edit cancel attempt.
Generated with the assistance of an AI coding tool.
In BIM_PT_type_attributes and BIM_PT_object_attributes (when
the active object is a type), attribute value buttons now use
"type.<Attr>" as the selector key so the operator finds
matching occurrences via their relating type rather than the
occurrence's own (often unset) attributes.

After selecting objects in the same container, copy a `location="Name"`
filter query to the clipboard and report it — consistent with the same
behaviour in SelectSimilarType, SelectSimilarAggregate, SelectIfcClass,

Generated with the assistance of an AI coding tool.
When a `+`-separated filter group returns no results, `FacetTransformer.facet_list`
was skipping the reset of `has_additive_facet_in_current_list` because the reset
was inside the `if self.elements:` guard. The stale flag caused the next group's
`add_default_elements()` to bail out early, leaving its element set empty and
silently dropping every subsequent group from the result.
Move the flag reset outside the guard so it always fires regardless of whether
the group produced any results.

End-to-end fillet flow on top of the helpers + recreate_wall hook
(landed in the previous commit). Users select two LAYER2 walls, click
the fillet entry icon, drag the live radius widget, and validate to
replace the corner with a curved LAYER2 corner wall (banana body).
Operators (5):
* EnableWallFilletPreview: 2-wall selection → validates LAYER2 +
straight axis + zero-slope + intersect-or-joined state → seeds the
preview props with a default radius computed from the shorter
available leg.
* FinishWallFilletPreview: dispatches CreateWallFillet with the tuned
radius; clears preview state on FINISHED, preserves it on failure so
the user can re-tune without re-selecting.
* CancelWallFilletPreview: clears preview state, no IFC mutation.
* EnableWallFilletPreviewFromCorner: pen-icon re-edit on an existing
fillet corner — pre-fills the preview from the corner's BBIM_Wall
pset + walks the inverse graph to recover wall A and wall B.
* CreateWallFillet: deletes any prior corner + A↔B path connection,
shortens A and B to the tangent points, instantiates a corner wall
from A's type, unassigns the swept-layer material/type (the explicit
banana body MUST own its geometry), assigns the dominant material,
rebuilds the body, sets a straight 2-point chord axis, stores
BBIM_Wall.IsFilletCorner+FilletRadius, reconnects A and B to the
corner with NOTDEFINED on the corner's side.
Gizmo groups (2 new + entry icon on existing):
* GizmoWallFilletPreview: visible while a preview is active. Bundles
a radius_dim widget at the arc apex, a trim_dim widget along wall A
expressing the same DOF via the leg setback distance
(trim = |radius| * tan(sweep/2)), and validate / cancel icons
anchored above the apex in screen-up.
* GizmoWallFilletReedit: pen-icon entry on an existing fillet corner
wall (single-selection, BBIM_Wall.IsFilletCorner set, both neighbour
connections present). Mutually exclusive with an active preview.
* GizmoWallJoinIntersection now stacks a fillet entry icon
(VIEW3D_GT_fillet → bim.enable_wall_fillet_preview) above the
existing join/unjoin icon in the joined and intersect state branches.
Property + decorator infrastructure:
* prop.py: BIMWallFilletPreviewProperties (Scene-level draft) +
BIMPreviewProperties umbrella with only the wall_fillet pointer.
The umbrella is the seam preview_base.py (landed in PR3) already
reads via getattr(scene, "BIMPreviewProperties", None).
* decorator.py: _stroke_lines_alpha helper + WallFilletPreviewDecorator.
Polls is_active; renders leg projections + arc + arc-center
construction lines from tool.Wall.compute_wall_fillet_geometry.
* __init__.py: registers operators + gizmo groups + property groups +
wires Scene.BIMPreviewProperties.
* handler.py: WallFilletPreviewDecorator.install/uninstall in
_install_decorators — always installed, self-polls on is_active.
Drive-by: extract gizmo.get_screen_up(billboard_rot) helper —
the local +Y of a billboard rotation is the camera's screen-up world
direction. Replaces 4 inline `billboard_rot @ Vector((0.0, 1.0, 0.0))`
sites added across the fillet feature's gizmo groups.

DecorationsHandler now caches dissolved edges (mesh-keyed), world-space
draw payload, and GPUBatch objects with per-object epoch invalidation —
moving one wall doesn't wipe 50 opening caches. Object-mode dissolve
removes triangulation noise; 2-pass depth-test split dims occluded lines
instead of hiding them. Edit-mode behavior unchanged.
Also: disable viewport shadows for IfcFeatureElementSubtraction objects,
and wire DecorationsHandler.uninstall() into the model module's
unregister() so the new persistent handlers don't leak on addon disable.

Eleven module-level helpers in wall.py that the upcoming wall-fillet
operators + gizmo groups depend on. Each is self-contained or
references only helpers earlier in the file; the operators and
gizmos themselves land in follow-up commits.
* _wall_fillet_props / _wall_fillet_preview_active /
_wall_fillet_preview_walls: thin read-side accessors over the
BIMPreviewProperties.wall_fillet pointer (added with the
operators commit). Safe today: get_preview_props returns None
until the pointer is attached.
* _walls_have_zero_slope_for_fillet: validates that input walls
are vertical (x_angle ~ 0); slanted-extrusion fillets require
swept-along-curve geometry the banana profile builder doesn't
support.
* _build_curved_corner_body_representation: builds the banana
(annular sector) IfcExtrudedAreaSolid as a polyline-tessellated
IfcIndexedPolyCurve.
* _apply_fillet_corner_geometry: positions the corner wall at
tangent_a and rebuilds its body. Shared by the creation operator
and the regenerate path.
* _resolve_two_walls: pulls (active, other) from a 2-wall
selection, validates both as LAYER2 + straight-axis + not-already-
a-fillet-corner.
* _pick_dominant_wall_material: returns the thickest layer's
material from an element's IfcMaterialLayerSet / Usage.
* regenerate_fillet_corner_wall: re-runs the geometry build from
BBIM_Wall.FilletRadius + current neighbour layer parameters.
Called by tool.Model.recreate_wall when the IsFilletCorner pset
is set; the FIXME(PR4) placeholder in recreate_wall is dropped.
* _wall_fillet_gizmo_x_matrix: 4x4 placement matrix with local +X
aligned to a world-space direction; used by the fillet preview
gizmo group.
Centralises the IsFilletCorner pset read as
tool.Parametric.is_fillet_corner_wall — replaces 3 inline
get_pset(element, "BBIM_Wall", "IsFilletCorner") sites
(tool.Model.recreate_wall, tool.Model.recalculate_walls,
tool.Parametric.is_path_connectable_wall) plus the new
_resolve_two_walls call.

The framework's parametric-edit icon row currently binds an array
icon to bim.add_array_from_feature_edit, but the supporting per-
feature add-array flow and gizmo positioning haven't fully landed.
Showing the icon today lets the user click it and trigger a half-
wired flow.
Force the icon hidden inside the props.is_editing branch of
BaseParametricGizmoGroup.update_editing_gizmos. The else-branch
(not editing) already hides it, so this just mirrors that behavior
during edit mode. Drop this gate when array integration completes
to re-enable the icon position + visibility plumbing.

The extend-X / extend-Z icons in GizmoWallEdition's cursor row are
billboarded toward the camera; without orientation polish they
always point in the same screen-space direction regardless of which
wall endpoint the click will move (or whether the cursor sits above
or below the wall top). New helper mirrors the icon's local-X (extend-X)
or local-Y (extend-Z) axis so each arrow points toward the end it
will move:
* Extend-X: walk wall midpoint to figure out which endpoint stays
fixed (cursor past midpoint → ATSTART stays; cursor before midpoint
→ ATEND stays). Project the fixed endpoint into screen-space and
flip the arrow when the gizmo's anchor sits on the same side.
* Extend-Z: flip when the cursor is below the wall top (within
EXTEND_FLIP_EPSILON tolerance).
Called once per resolved cursor gizmo from
``GizmoWallEdition._update_cursor_gizmos``, after the gizmo's
``matrix_basis`` is set by ``gizmo.billboarded_at``. Reuses
``gizmo.should_flip_extend_arrow`` + ``EXTEND_FLIP_MIRROR_X/Y`` +
``EXTEND_FLIP_EPSILON`` already on tool.

GizmoWallJoinIntersection's unjoin only fires when exactly two walls
are selected and surfaces one icon at their shared corner — useless
when the wall has 3+ joins and the user wants to disconnect just one.
* UnjoinWallPathConnection: surgical counterpart to UnjoinWalls.
Disconnects the active wall from a single partner wall identified
by IFC GlobalId (invariant under Blender-object renames + file
save/reload + undo). Walks both inverse arrays of the active wall
for the specific IfcRelConnectsPathElements joining the pair —
matches DumbWallJoiner.split's pattern and avoids disconnect_path's
direction-sensitivity. Resyncs both walls' draft props after the
recreate_wall pass.
* GizmoWallUnjoinSingle: activates on exactly-one selected
LAYER2 wall. Preallocates a pool of 16 unjoin icons (Blender forbids
gizmo allocation outside setup(); ATSTART + ATEND + ATPATH rels are
rarely more than a handful). Per-frame, iterates _iter_path_connections,
positions one billboarded icon at each join via
tool.Wall.path_connection_location_world, and hides the rest. Each
visible icon's bound operator carries the partner GlobalId, so a
click removes only that one rel.
* model/__init__.py: register both classes alphabetically.
Mutually exclusive with GizmoWallJoinIntersection via poll() — that
group requires len(selected) == 2; this one requires 1.
Generated with the assistance of an AI coding tool.
The single-wall unjoin gizmo needs to enumerate every
IfcRelConnectsPathElements a wall participates in, regardless of which
side of the rel the wall was authored on, and place an icon at each
join's physical location. Two helpers carry that work:
_path_connection_location_world wraps core.compute_path_connection_location
at the Vector boundary. _iter_path_connections walks ConnectedTo +
ConnectedFrom, normalises orientation to (other, self_ct, other_ct),
and filters non-wall partners + None refs so per-frame gizmo positioning
survives malformed IFC.
Generated with the assistance of an AI coding tool.
After a one-shot wall IFC mutation (unjoin / split / merge / extend /
join-at-corner …) the always-visible gizmos on the OTHER side of the
join can be left reading stale ``BIMWallProperties`` — the IFC
geometry moved but the draft props that drive the gizmo handles still
point at the pre-mutation numbers, so a subsequent edit-mode enter
shows the wall at its old length / position.
* New ``_maybe_resync_wall_props_from_ifc(obj)``: re-primes a single
wall's draft props from current IFC, with guards for non-walls,
non-parametric walls, and walls in an active draft session (the
draft is then the source of truth, not IFC). Must run from an
operator ``_execute`` — ID writes from gizmo refresh raise.
* New ``_resync_walls_after_mutation(objs)``: iterates the above
across a selection.
* Six existing mutation operators gain a resync call after their
``core.*`` / ``DumbWallJoiner`` mutation completes:
UnjoinWalls, ExtendWallsToUnderside, ExtendWallsToWall, SplitWall,
MergeWall, JoinWallsIntersection. MergeWall resyncs only the
surviving wall — the active wall is the deletion target.

Bundle of bugs surfaced when exercising the new gizmo framework
end-to-end in a live Blender session after the
bim/module/drawing/gizmos.py refactor + TypeAccessor/CycleType/PickType
mixins landed.
Register / annotation resolution
* parametric_lifecycle.py: hoist `entity_instance` import out of
TYPE_CHECKING so typing.get_type_hints resolves the
Callable[[entity_instance], bool] annotation at operator registration
(CycleDoorType, CycleWindowType, CycleStairType failed with NameError).
Clarify the INTERFACE return contract on the picker entry-point so
readers see why the gizmo step stays off the undo stack.
Framework callable contracts
* model/wall.py, door.py, window.py, stair.py: migrate `props_getter`
and `element_checker` from bl_idname strings to bound classmethods
on tool.Model / tool.Parametric. BaseParametricGizmoGroup.get_props
expects a callable; the string form raised TypeError on first
gizmo poll.
* model/door.py, model/stair.py: drop the dead `prop_path=` operator
kwarg from create_arc_gizmo / create_icon_gizmo call sites. The
framework helper blindly setattrs every kwarg onto the operator's
OperatorProperties, but ToggleDoorSwing / ToggleStairProperty don't
declare prop_path — the setattr raised mid-setup_element_specific_gizmos,
so self.gizmo_door_type / self.lock_gizmo never got assigned and
every subsequent draw_prepare tornadoed AttributeError. Nothing
reads op.prop_path anywhere; the kwarg was dead data.
Dispatcher operators
* model/array.py: add EnableEditingParametric (the framework pen-icon
dispatcher that routes to a per-feature edit operator by bl_idname
string) and AddArrayFromFeatureEdit (binds the framework's array
icon to bim.add_array on the current parametric draft).
* model/__init__.py: register both new operators.
Per-frame robustness
* drawing/gizmos.py: guard BaseParametricGizmoGroup.draw_prepare with
is_setup_complete() — matches the existing guard in refresh() and
in BaseSchematicGizmoGroup.draw_prepare(). Defense-in-depth: when
any subclass's setup raises mid-way, draw_prepare now no-ops cleanly
instead of per-frame AttributeError-tornadoing on whatever attribute
the failed setup phase was meant to populate.
* model/decorator.py: guard ProfileDecorator.__call__ against
context.active_object is None. The decorator is a per-frame
viewport draw handler; deselecting or deleting the active object
while it's installed crashed on obj.mode access. Treat None the
same as "no longer in edit mode" — uninstall + fire the exit
callback if present.
* geometry/data.py: ViewportData.load() populates `data` before
flipping `is_loaded`, so a raise from cls.mode() no longer leaves
the class flag-set but data-empty for subsequent reads.

Three concerns bundled into one cohesive refactor of gizmos.py
(splitting them surgically requires intermediate commits with
duplicate same-named classes that Python can't parse):
1. Framework primitives — StaticTrisGizmoMixin + TexturedQuadGizmoMixin
replace the older TrisGizmoMixin. New module-level helpers:
_get_static_tris_shader / _get_static_tris_batch / clear_static_
tris_cache for cached GPU batch reuse, _draw_outline_and_body for
the shared outline-then-body render path, draw_tris_with_outline
as the public wrapper. billboarded_at(world_pos, billboard_rot,
scale) is the canonical billboard-matrix helper; should_flip_extend_
arrow encapsulates the view-aware mirror decision for extend
gizmos; get_warning_color_from_prefs reads the user's warning
color.
2. Config classes — BaseValueGizmoConfig (shared visibility + dimension-
text contract), CountGizmoConfig (array N indicator),
DimensionGizmoConfig (length / height / depth labels), IconActionConfig
(icon-only gizmos that invoke an operator on click). DimensionRenderer
draws the actual numeric label using BLF.
3. Icon classes — each rewritten on StaticTrisGizmoMixin so they share
the cached GPU batch + outline-then-body render path:
GizmoLockOpen / GizmoLockClosed (replacing the single-state
GizmoLock), GizmoArc, GizmoFillet, GizmoWallCornerIcon,
GizmoWallTeeIcon, GizmoPen / GizmoValidate / GizmoCancel (the
parametric-edit triad), GizmoPlus / GizmoMinus / GizmoTrash,
GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator (array
context indicators with a small digit-rendering helper for the "xN"
count label), GizmoMerge / GizmoSplit / GizmoUnjoin (wall-join
icons), and GizmoMenu (textured-quad icon-action menu trigger).
The legacy TrisGizmoMixin, GizmoLock, and DimensionDrawConfig are
removed; downstream callers in subsequent PR4 commits swap to the
new mixin and config classes when their feature operators land.
CycleTypeMixin / PickTypeMixin / TypeAccessorBase live in
bim.parametric_lifecycle (previous commit). The three mixins are
re-exported from gizmos.py here so feature-module access via
``gizmo.<MixinName>`` keeps working until PR5 cleanup drops the
re-exports.
bim/module/drawing/__init__.py is updated in the same commit to
register the 11 new gizmo classes (GizmoLockOpen / GizmoLockClosed /
GizmoFillet / GizmoWallCornerIcon / GizmoWallTeeIcon / GizmoTrash /
GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator /
GizmoUnjoin / GizmoMenu) — without that, the new classes exist in
gizmos.py but aren't usable as bpy gizmo types.
Generated with the assistance of an AI coding tool.
Three operator mixins for type-selection ops on parametric features
(door type-cycle, window type-pick, stair type-cycle, railing
type-pick, roof type-cycle, etc.). Each shares the same contract:
* ``element_checker`` validates the active object is the expected
IFC type
* ``props_getter`` resolves the BIM<Name>Properties group
* ``type_literal`` is the Literal type whose args drive the enum
* ``type_attr`` is the PropertyGroup field to read/write
* ``skip_element_check=True`` bypasses element validation (for
operators that target a non-IFC context)
CycleTypeMixin shift-click reverses direction (forward by default).
PickTypeMixin opens a popup menu and routes the picked value
through execute() so F6 redo / EXEC_DEFAULT reach the apply path.
The PickType modal-handler dance waits for LEFTMOUSE release before
opening the menu when invoked mid-click (e.g. from a gizmo's
target_set_operator) so Blender's drag-through-pick gesture doesn't
commit an accidental item.
Ships standalone — the next commit's gizmos.py framework refactor
re-exports these names from bonsai.bim.parametric_lifecycle so
gizmo modules can spell ``gizmo.CycleTypeMixin`` / ``gizmo.PickTypeMixin``.
Concrete operator subclasses land in subsequent PR4 commits per
feature (door / window / stair / railing / roof).

Two paired test files for the framework infrastructure landed
earlier in this PR.
test_decorator_cache.py (11 tests):
* The 4-hook invalidation list (depsgraph_update_post + undo_post +
redo_post + load_post) is symmetrically managed by
install_decorator_cache_handlers / uninstall_decorator_cache_handlers.
A future edit that drops a hook from one side without the other
would land as a Blender segfault when a cached bpy.types.Object
ref outlives its underlying ID block — the regression must surface
as a test failure first.
* install is idempotent (calling twice doesn't double-register).
* uninstall when not installed doesn't raise.
* The bump handler accepts Blender's variadic args.
* The depsgraph predicate gates correctly: bumps on Object geometry
or transform updates, silently skips on Material / NodeTree / Image
updates (which would otherwise rebuild every cache on every node
edit).
* TokenCache.get_or_compute short-circuits on key+token match and
recomputes when the token bumps.
test_undo_resync_parametric_drafts.py (3 tests):
* UNDO_REGENERATORS keys must all be in tool.Parametric.EDIT_TYPES.
A typo would silently no-op on Ctrl+Z, restoring the desync the
helper is meant to prevent.
* The dispatcher skips objects with no active parametric edit
(undo_post fires for every undo, most of which touch zero drafts).
* The dispatcher silently skips parametric types that have no
UNDO_REGENERATORS entry (door / window / array are IFC-derived
with no draft preview mesh — they don't need a regenerator).
Mocks use spec=bpy.types.Depsgraph / spec=bpy.types.DepsgraphUpdate
/ spec=tool.parametric.ParametricObject so typos in mocked-attribute
access fail loudly (CLAUDE.md test discipline).

Splitting a wall through a door orphaned the door (door.FillsVoids
became empty). The fill rel was being reassigned by setting its
RelatedBuildingElement slot — schema-wise that's the filling slot, not
the wall slot — so when remove_feature deleted the old opening it
also cascade-removed the rel. Transferring via RelatingOpeningElement
keeps the rel pointing at the new opening so the door stays
associated. Pre-existing bug from 5a6476a57, surfaced by ef144dce2.
Generated with the assistance of an AI coding tool.
DumbWallJoiner.split assigned openings by projecting the opening's
centre-point onto the wall axis, so any opening whose footprint
straddled the cut was silently dropped from whichever wall its centre
missed. Now the full axis-projected extent (via ifcopenshell.geom.
create_shape) drives the assignment; for filled openings whose void
straddles the cut, a pure-void copy is added back to the neighbour
wall so its body is also cut.

Five inline copies of the same defensive pattern lived across
``tool/parametric.py``, ``bim/parametric_lifecycle.py``,
``bim/module/model/preview_base.py`` (twice), and as a near-twin
in ``tool/blender.py:update_all_viewports`` itself.
``tool.Blender.update_all_viewports`` already covered the
``tag_redraw`` job but used an ``assert context.screen`` that would
raise during background-mode operators or early-load_post calls
where ``screen`` legitimately is None. Relax to a defensive
``getattr(context, "screen", None)`` + silent return so the helper
fits every caller's needs, then collapse the 4 inline copies to
single calls.
Net -9 LOC. The helper now describes its contract ("silent no-op
when no screen attached") rather than naming specific callers, so
moving a caller doesn't rot the docstring.

Ctrl+Z / Ctrl+Shift+Z on an in-progress parametric draft (wall /
stair / roof) used to leave the preview mesh frozen in its
pre-undo shape — the IFC mutation rolls back but the bmesh built
from draft props doesn't repaint.
Add a registry of per-type regenerator functions
(``UNDO_REGENERATORS``) that re-build each type's preview mesh
from its current props. The dispatcher
``resync_parametric_drafts_after_undo`` walks all objects, skips
any without an active parametric edit, looks up the regenerator
by feature name, and calls it. Tagged 3D viewports for redraw.
Types without an entry (door / window / railing / etc.) are
intentionally absent — they're IFC-derived, so the undo's
representation rollback + next-frame refresh already repaints
correctly without a draft-side regenerator.
Undo/redo wiring is self-installed by
``bonsai.bim.parametric_lifecycle``: a ``@persistent``
``_resync_on_undo`` callback dispatches into the registry, and
``install_parametric_lifecycle_handlers()`` /
``uninstall_parametric_lifecycle_handlers()`` append/remove it
from ``bpy.app.handlers.undo_post`` and ``redo_post``.
``bim/__init__.py``'s ``register()`` calls the install function
*after* the central ``handler.undo_post`` / ``redo_post`` appends
so the regenerators see restored IFC state — ``bpy.app.handlers``
fire in append order. ``handler.py`` itself stays ignorant of the
parametric subsystem. The lazy function-local imports in each
regenerator break the addon-load cycle —
``bonsai.bim.parametric_lifecycle`` loads before
``bim/module/model/*``.

Three changes to the shared Enable/Finish/Cancel mixins:
1. Always-on drift triad on ParametricEditMixinBase. The base now
provides ``_handle_drift_on_enable`` / ``_handle_drift_on_finish``
/ ``_handle_drift_on_cancel`` classmethods, called from the
per-mixin ``_enable_one`` / ``_finish_one`` / ``_cancel_one``.
Pre-edit Blender-side translations commit to IFC on Enable
(apply_scale=False — only translation/rotation, not the user's
accidental scale), in-edit drag commits on Finish (apply_scale=True),
and Cancel restores the committed IFC placement via
``restore_or_rebaseline_placement``. Prevents the
"uncommitted drag disappears on Finish" and "preview snaps back
on Cancel" UX bugs.
2. ``_ParametricEditMixinBase`` renamed to ``ParametricEditMixinBase``
(public). Per-feature mixins that need to subclass directly
(e.g., when neither FeatureModifier nor PathPreserving fits)
can do so without reaching into a private name.
3. ``_update_modifier_bmesh`` (PathPreserving) renamed to
``_restore_viewport_after_cancel``. The old name was inaccurate
for subclasses that load a different IFC representation on
Cancel rather than rebuilding a bmesh preview from props.
Plus two polish changes:
* ``_mark_type_thumbnail_dirty`` helper on the base centralises the
``ifcopenshell.util.element.get_type`` + thumbnail-mark pattern
that both mixins repeated inline.
* ``FeatureModifierEditMixin._cancel_one`` and
``PathPreservingEditMixin._cancel_one`` wrap the restore in
``try/finally`` so ``props.is_editing = False`` flips even on
partial restore failure. Without this, a Cancel that raised
mid-restore would leave the user locked out of the edit lifecycle.
* ``PathPreservingEditMixin._finish_one`` / ``_cancel_one`` skip the
pset commit + viewport rebuild when the draft equals the stored
pset (no-op Enable→Finish round-trip should not pollute the
representation list or burn an undo entry).
``FeatureModifierEditMixin._finish_one`` now routes the pset commit
through ``tool.Pset.write_bbim_data`` instead of inlining the
``createIfcText(json.dumps(...))`` + ``ifcopenshell.api.pset.edit_pset``
dance. Two test assertions updated to match.
Generated with the assistance of an AI coding tool.
Three concerns folded into ``load_post`` argue for separation:
1. Save-file invariants every load must re-establish (msgbus
subscription, owner-settings, thumbnail cache, draft-flag healing,
blend-warning flag, H5 lock probe).
2. User-preference-driven UI setup (toolbar, workspace, viewport
shading, panel hijack, snap defaults).
3. Viewport overlay sync (every decorator's install/uninstall).
Pull each into its own function (``_apply_save_file_invariants`` /
``_apply_user_preferences`` / ``_install_viewport_overlays``). The
``load_post`` callback becomes a 3-line orchestrator. Each phase
is independently call-able from tests and from PR4 features that
need to re-trigger one phase without the others.
Two new hooks land with the decompose:
* ``tool.Parametric.heal_stale_edit_flags()`` + ``discard_pending_previews(scene)``
fire in ``_apply_save_file_invariants``. The first clears
object-level ``BIM<Name>Properties.is_editing`` flags that lost
their backing IFC element across a load; the second clears
scene-level ``BIMPreviewProperties.<x>.is_active`` so saved
preview state never resurfaces with no UI to interact with it.
* ``install_decorator_cache_handlers`` / ``uninstall_decorator_cache_handlers``
wrap the decorator install/install pass in
``_install_viewport_overlays``. The bump handlers append to
``depsgraph_update_post`` + ``undo_post`` + ``redo_post`` +
``load_post`` so the previous commit's ``TokenCache`` in
``tool.System.get_decoration_data`` finally invalidates on
structural scene changes.

Shared helpers for Bonsai's Scene-level parametric preview flows.
Two PR4 features will consume this — MEP bend preview and wall
fillet preview — both following the same shape:
Enable<X>Preview — populates draft on Scene.BIMPreviewProperties.<x>
Gizmo<X>Preview — polls on is_active, surfaces tunable widgets
<X>PreviewDecorator — GPU lines while is_active is True
Finish<X>Preview — bpy.ops.bim.<verb>(...) with draft kwargs
Cancel<X>Preview — pure state reset
The module hosts the cross-cutting accessors (``get_preview_props``,
``is_preview_active``), lazy-closure factories for gizmo dimension
callbacks (``make_props_callback`` / ``make_dim_getter`` /
``make_dim_setter`` — defensive against missing scene / freed RNA
struct on file open / undo), the Enable-time IFC-placement sync
(``sync_uncommitted_moves``), and the Esc + load_post discard
machinery (``PREVIEW_CANCEL_OPS`` registry, ``try_cancel_active_preview``,
``discard_pending_previews``).
Ships standalone — the consumer features land in PR4 (preview
PropertyGroups, Enable/Finish/Cancel operators, gizmo groups,
decorators, Esc keymap binding). All accessors are defensive
against missing PropertyGroups / operators on v0.8.0 — calling
``discard_pending_previews(scene)`` from the next commit's
load_post hook is a no-op until PR4 attaches BIMPreviewProperties.

System decoration draws on every viewport refresh — the
``_build_decoration_data`` body walks every distribution element,
resolves connected ports, builds the vert/edge arrays for the GPU
batch. A bare call per frame burns time on an unchanged scene.
Add a single-entry cache keyed on ``(decorator_cache_token,
id(decorated_elements_set))``. Reads short-circuit when neither
component moved:
* ``decorator_cache_token`` from ``bim.decorator_cache`` invalidates
on depsgraph / undo / redo / load via the bump handler.
* ``id(decorated_elements_set)`` invalidates when
``SystemDecorationData.load()`` reassigns the set (e.g. when the
user changes the set of decorated systems via the panel).
The handler that bumps the token is installed in the next commit
(bim/handler.py decompose). Until then the token stays at 0, so
the cache only hits when ``id()`` also matches — degraded behaviour
during the bisect window but not incorrect.
Generated with the assistance of an AI coding tool.
New helper module for POST_VIEW decorators. Exports:
* ``get_decorator_cache_token()`` — global int counter consumers
include in their cache key so the value invalidates on structural
scene changes.
* ``_bump_decorator_cache_token()`` — ``@bpy.app.handlers.persistent``
callback that increments the token. Gates on the depsgraph payload
so animation playback / driver evaluation doesn't churn the token.
* ``install_decorator_cache_handlers`` / ``uninstall_…`` — idempotent
append / remove against depsgraph_update_post + undo_post + redo_post
+ load_post. Called once from ``bim.register`` / ``unregister``.
* ``TokenCache[T]`` — single-entry memoiser keyed on ``(caller_key,
token)``. Cached ``bpy.types.Object`` references can't outlive the
underlying ID blocks because any depsgraph / undo / load bumps the
token and forces a recompute.
This commit ships the module standalone. The next commits in this
PR wire it: tool/system.py adds the cache wrap on get_decoration_data
and bim/handler.py installs the bump callbacks. Until both land,
the module is intentionally dead code — keeps the diff narrow and
the commit history bisectable.
Generated with the assistance of an AI coding tool.
Five code paths in slim PR2 referenced symbols that don't exist in
v0.8.0's bim layer, raising at first call. Plus three type
annotations that ty flagged as unresolved.
1. tool/system.py:get_decoration_data — drop the cache layer that
keyed on a token from a bim/decorator_cache.py module. The cache
is dead-or-broken in slim: the depsgraph bump handler that would
invalidate the token lives in PR3's bim/handler.py decompose, so
the token stays at 0 forever. Either the cache never hits
(decorated_elements rebuilt → new id() per call) or returns
stale data (list reused). Revert to direct
`_build_decoration_data()` calls. PR3 reintroduces the cache
atomically: decorator_cache module + handler install + cache
wrap + tests. Keeps `_build_decoration_data` extraction
(cleaner than v0.8.0's monolithic version regardless of cache).
2. tool/spatial.py — add `get_host_element` + `get_host_wall`.
The interface stubs in `core/tool.py:1037-1038` were declared
but never implemented. `tool/duplicate.py:99` (object duplication
with fills) and `tool/model.py:1260` (array per-child opening
mirror) call these and would raise AttributeError.
3. tool/model.py:recreate_wall — drop the fillet-corner branch
that function-locally imports `regenerate_fillet_corner_wall`
from `bim/module/model/wall`. The function lands with PR4; fall
through to the straight-extrusion path preserves v0.8.0
behaviour for fillet walls until then. Tag FIXME(PR4).
4. tool/model.py — drop `get_pipe_segment_props` /
`get_duct_segment_props` accessors. Their return types reference
`BIMPipeSegmentProperties` / `BIMDuctSegmentProperties` which
land with PR4's prop.py; calling either accessor on v0.8.0 would
AttributeError on `obj.BIM<X>SegmentProperties`. Zero callers in
slim — PR4 reintroduces both accessors together with the
PropertyGroups they wrap. Also drops the matching TYPE_CHECKING
imports.
5. tool/blender.py:557 — `Mapping[type[ViewportDecorator], bool]`
needs the qualified `Blender.ViewportDecorator` because the
annotation is on a method INSIDE the same nested class; the
bare name doesn't resolve at type-check time.
6. core/tool.py Surveyor — drop the `obj: "bpy.types.Object"` /
`z: float` / `-> float` / `-> None` annotations on
`get_z_rotation` / `set_z_rotation`. The `@interface` decorator
wraps each method as `classmethod(abstractmethod(...))` at
import time, but ty doesn't track the wrap and flags every
call site as `missing-argument` plus the `pass` body as
`empty-body` against the declared return type, plus the
`bpy.types.Object` forward-ref as `unresolved-reference`.
Reverting to v0.8.0's untyped style (matching the sibling
`get_absolute_matrix(cls, obj)` stub) clears six ty errors at
the cost of zero runtime semantics — the abstract stubs only
serve as registry markers, concrete `tool.Surveyor.*` carries
the real signatures.

Surfaces any regression in:
* the modules dict in bim/__init__.py (added a folder, forgot the entry)
* PointerProperty wiring on bpy.types.{Scene,Object,...}
* registry-driven GizmoPreferences<Name> auto-registration in
tool.Parametric.iter_gizmo_preference_classes
* bpy.app.handlers append/remove balance
* every register()/unregister() across the 45+ feature modules
as a single PASSED/FAILED test instead of the silent "addon failed to
enable" users encounter in a fresh Blender. Paired with the existing
test_parametric_registry.py contract tests, this catches both the
registry-shape regressions (operators/PropertyGroups/predicates) and
the registration-mechanics regressions (PointerProperty types not
registered before their owners).

Three corrective fixes folded into one commit. All surface as
addon-load / save-time exceptions on v0.8.0's bim layer because
PR2's tool.Parametric refactor over-committed to the PR4 contract.
1. iter_gizmo_preference_classes — the previous implementation
returned only the shared GizmoPreferencesFeature class. v0.8.0's
bim/ui.py declares PointerProperty fields ('door', 'window', ...)
on GizmoPreferences that point at per-feature
GizmoPreferences<Name> classes; those must be registered BEFORE
GizmoPreferences itself. The shared-class-only return broke
addon registration with:
'door' PointerProperty could not register (see previous error)
Restore the v0.8.0 per-feature lookup (iterate EDIT_TYPES, look
up each GizmoPreferences<Capitalize(name)> on ui_module) and
keep the shared-class lookup as forward-compat. Tag FIXME(PR5).
2. EDIT_TYPES — drop the array / pipe_segment / duct_segment
entries from the registry. Their bim.finish_editing_<name>
operators land with PR4. Registering them in PR2's EDIT_TYPES
without the operators makes auto-commit-on-save dispatch a
non-existent finish_op for any object whose
BIM<Name>Properties.is_editing flag is True, raising:
RuntimeError: 'bim.finish_editing_array' must be a registered
tool.Ifc.Operator subclass for undo-safe IFC mutation
PR4 re-adds the three entries together with their operators.
Tag FIXME(PR4).
3. tool.Blender.Modifier shim block — upgrade the prose comment to
a formal FIXME(PR5) marker so the PR5 cleanup sweep finds it via
grep alongside every other tagged shim site.

Fixes addon-load ImportError that surfaces when tool/geometry.py
and tool/model.py (extracted in C8 / C9) reference symbols that
don't exist on v0.8.0:
* bim/ifc.py: get_cache_or_detect_lock — IfcStore.get_cache
variant that tracks the multi-instance-cache-locked-by-other-
process flag, sets it on PermissionError, clears it (along with
the dismiss flag) on subsequent success. Used by
tool.Geometry.* to gate IFC cache reads without crashing when
another Blender instance holds the cache lock.
* tool/cad.py: WELD_TOLERANCE constant + paired CAD helpers
(auto-detect-curves vertex precision, polyline normal helpers,
etc.) used by tool.Model.* + by the parametric model operators
that land in PR4.
Both modules had zero upstream commits since the gizmos-8088 fork
point — safe bulk extraction. PR4 has no caller-line work for
either file (the additions are pure additions, no existing API
removed); the v0.8.0 callers of get_cache_or_detect_lock and
WELD_TOLERANCE are the PR2-scope files that needed them.

The previous commit moved is_<type> predicates off tool.Blender.Modifier
onto tool.Parametric, and earlier C4 moved the Array helper bag off
tool.Blender.Modifier.Array onto tool.Array. PR4 will migrate every
caller; this commit keeps the OLD entry points alive as thin delegates
so PR2 ships without breaking ~30 caller sites that still spell the
old API in v0.8.0:
* tool.Blender.Modifier.is_door / is_railing / is_roof / is_stair /
is_wall / is_window — delegate to tool.Parametric.is_<type>.
* tool.Blender.Modifier.Array.bake_children_transform / constrain_
children_to_parent / get_all_children_objects / get_all_objects /
get_children_objects / get_modifiers_data / remove_constraints /
set_children_lock_state — delegate to tool.Array.<same name>.
These shims are removed in PR5's cleanup commit once PR4 has rewritten
the call sites in bim/import_ifc.py, bim/module/geometry/operator.py,
bim/module/geometry/data.py, bim/module/model/array.py + the per-feature
operators (door, wall, window, railing, roof, stair, ui).

tool.Parametric becomes the central registry for Bonsai's parametric
features (wall, slab, door, window, railing, roof, stair, plus
mep-segment variants). Each feature registers a ParametricObject spec
declaring its enable/finish/cancel op names, props accessor, regen
callback, and is_element_type predicate.
Public surface:
* tool.Parametric.WALL / SLAB / DOOR / WINDOW / RAILING / ROOF /
STAIR / PIPE_SEGMENT / DUCT_SEGMENT — typed accessors per feature.
* tool.Parametric.is_wall / is_door / is_window / is_railing /
is_roof / is_stair — element-type predicates that move off
tool.Blender.Modifier into the parametric registry. The next
commit adds backward-compat shims on tool.Blender.Modifier so
v0.8.0 callers keep working.
* tool.Parametric.is_object_editing(obj) — returns the registered
feature an object is currently editing, or None.
* tool.Parametric.run_bim_op(op_name) — invoke a parametric op by
bl_idname.
* tool.Parametric.heal_stale_edit_flags — clear is_editing flags
on file load so a saved-mid-edit project doesn't leave gizmos
poll-locked.
* supports_build_edit_lifecycle field on ParametricObject — declares
whether the feature implements the build/edit/cancel triad.
The previous bare `print(f"Bonsai: commit of {obj.name!r} via
{finish_op} failed: {e}")` exception-handler is replaced with
logger.warning(..., exc_info=True). Same channel (Bonsai configures
logging to the Blender console at WARNING level), strictly more
information (full traceback), correct idiom for an error-path
message. A second logger.warning is added for parametric predicate
failures, also exception-handler scope.
Generated with the assistance of an AI coding tool.
tool.Model gains:
* get_pipe_segment_props / get_duct_segment_props — typed prop accessors
for the MEP-segment edit lifecycle.
* resolve_active_props_for_edit — picks the right BIM*Properties to
drive a parametric edit triad based on the active object's IFC class.
* mirror_parent_void_fillings_to_children — when an array parent has
hosted fillings (door/window in a wall), replicate the same fill
rels onto each array child. Uses tool.Array.get_parametric_propagation_
targets so the propagation stays within the array family (the old
get_all_element_occurrences over-propagated to standalone occurrences
of the same type, which silently mutated unrelated arrays).
* unshare_opening_representation — fork a shared IfcShapeRepresentation
so editing one opening doesn't mutate its array sibling.
* duplicate_ifc_objects gains a post-condition select-restore on the
array parent so callers don't get a deselected parent for N>=2 arrays.
sync_object_ifc_position is kept as a thin delegate to
tool.Geometry.commit_placement_if_moved (the new home, added in C8) so
the 6 v0.8.0 callers in mep / product / system don't AttributeError;
PR4 migrates each caller and removes the delegate.
tool.Pset gains:
* upsert_pset — get-or-add-or-edit in one call.
* write_bbim_data — JSON-encode + write BBIM_* metadata in one call.
tool.Slab is new — slab-specific reads (active extrusion, axis
direction) used by the slab gizmos, pure-IFC, no PropertyGroup mutation.
Generated with the assistance of an AI coding tool.
Adds:
* get_body_representation(element) — DRY of the repeated
ifcopenshell.util.representation.get_representation(element, "Model",
"Body", "MODEL_VIEW") call across slab / wall / opening / stair /
roof / door / window / mep. One central place to read the body rep;
every caller stops re-spelling the four magic strings.
* has_axis_representation(element) — predicate for elements with a
GRAPH_VIEW Axis representation. Used by the wall/MEP path decorators
to skip elements without an unambiguous 1D path.
* has_material_styles(element) — predicate for whether the element
carries IfcStyledItem material assignments.
* restore_placement_from_ifc(obj, element) — snap obj.matrix_world back
to element's committed IFC placement + rebaseline the drift checksum.
* restore_or_rebaseline_placement(obj, element) — Cancel-flow helper:
restores if ObjectPlacement exists, just rebaselines the checksum if
not.
* detach_representation(product) — remove the active representation
from a product without deleting the entity (used by parametric
rebuilds that wipe + re-add).
commit_placement_if_moved docstring expanded with a "drop-in scope"
note so callers don't redundantly wrap it in an is_moved check that
the helper already does.
Switches the duplicate-aware helper calls (formerly tool.Root.*) to
tool.Duplicate.* now that the service exists (C6).
Generated with the assistance of an AI coding tool.
Adds:
* ViewportDecorator base class — install/uninstall/draw lifecycle for
3D viewport gpu overlays, with handler-rollback-on-failure so a
partial install can't leave dangling draw handlers.
* sync_all classmethod — drive each listed ViewportDecorator subclass
to its desired install state in one call.
* is_view_top_down + top_down_factor — viewport-camera orientation
predicates used by gizmo billboarding and decorator layout.
* get_screen_up_world — screen-up vector in world space for gizmo
text orientation.
* are_viewport_gizmos_enabled — central gate for the global
draw_gizmos_in_3d_viewport pref, replacing duplicated prefs reads.
* DecoratorColors NamedTuple + get_decorator_colors — single source
for the colour palette every viewport decorator binds.
Preserves Ryan Schultz's add_layout_hotkey_operator polish (719309571,
2026-05-25): the row-position move + separator(factor=1) between the
modifier and key icons stay intact in this extraction.

Extract the duplicate-aware relationship-walk + restoration logic
(get_decomposition_relationships, get_connection_relationships,
get_port_connection_relationships, recreate_decompositions,
recreate_connections, recreate_port_connections, consume_warnings)
out of tool.Root into its own service.
tool.Root's responsibility is identity and addressing of IFC roots;
the duplicate-aware bookkeeping of "before duplication, what relations
did this graph have, and how do I restore them on the new copies?"
deserves its own home. The split was already declared on core/tool.py
(C2); this commit lands the concrete tool.Duplicate implementation.
tool.Root keeps its own copies of the methods on v0.8.0's tool/root.py
during this PR so callers in bim/module/spatial/operator.py keep
working at runtime; the Root cleanup lands in PR4 alongside the
caller updates.

Adds:
* direction_from_port_pair(port_a, port_b) — derive the connect_port
direction kwarg from each port's FlowDirection (NOTDEFINED for
non-canonical pairs). Centralises a pattern that callers were
inlining inconsistently.
* tool.System.walk_connected_mep_elements — BFS over connected MEP
flow elements via IfcRelConnectsPorts.
* tool.System.get_port_world_position — port placement → world-space
Vector, used by the MEP path decorator.
* tool.System._build_decoration_data — cached decoration metadata
for the MEP system-path overlay.
Plus a get_port_relating_element return-type tightening (Union with
None) and a partial-init cycle workaround on bim.module.system.data
imports (now function-local — top-level import triggered the cycle
through tool.Ifc.Operator).

Top-level array-domain service extracted out of tool.Blender.Modifier.Array.
Owns the BBIM_Array pset graph navigation (constrain_children_to_parent,
remove_constraints, get_modifiers_data, get_children_objects,
get_all_children_objects, get_child_layer_index, bake_children_transform),
plus the Blender-side CHILD_OF constraint lifecycle that ties each child
replica to its parent's transform.
Array's own module gives the parent/child semantics a clean home — array
behaviour was previously scattered between tool.Blender.Modifier and ad-hoc
helpers in bim/module/model/array.py. The relocation eliminates the inline
duplication and gives Bonsai callers a single import surface.

Bpy-permitted wall reads — get_axis_local_extent, get_length_and_height,
get_x_angle, get_path_connection_location, walk_connected_walls — used
by gizmo lambdas that need wall dimensions and join topology without
the side effect of loading the wall's draft BIMWallProperties (the
loader mutates PropertyGroup state and would clobber the wall's own
gizmo state when both the wall and a hosted filling are selected).
All reads go through ifcopenshell.util.representation / .util.element
so the IFC graph stays the source of truth. tool.Wall consumes
core.model's PARALLEL_DOT_THRESHOLD + collinearity helpers (no inline
magic numbers).

Declares the bpy-free contract for tool services landing in subsequent
commits — tool.Wall, tool.Array, tool.System, tool.Duplicate (extracted
from tool.Root), tool.Parametric, plus minor additions on existing
interfaces (tool.Spatial.get_host_element / get_host_wall,
tool.Geometry.has_axis_representation / has_material_styles,
tool.Surveyor.get_z_rotation / set_z_rotation).
The @interface declarations are empty-bodied; concrete implementations
land in the per-service tool/* commits below. Keeping the contract in
core lets core/* helpers and tests reference the surface without
importing the concrete tool modules.
Moves get_decomposition_relationships + recreate_decompositions off
tool.Root onto the new tool.Duplicate (extraction of duplicate-aware

core/model.py gains:
* Three calibrated dot-product / distance thresholds — PARALLEL_DOT_THRESHOLD
(~2° from parallel, cos(2°) ≈ 0.9994), COLLINEAR_LINE_TOLERANCE (50mm
perpendicular distance for two parallel wall axes to share a line),
BASELINE_OFFSET_TOLERANCE — replacing inline magic numbers that the
wall-join classifier, fillet-state machine, and gizmo preview decorator
all read from.
* Pure wall-join geometry helpers (project_axis_intersection,
are_axes_collinear, classify_wall_join_state, wall_join_preview_lines,
resolve_extend_walls_target, extrusion_depth_from_vertical_height,
length_and_height_from_extrusion). They take primitive tuples + floats,
no bpy, no ifcopenshell — testable in the core lane.
core/product.py is new — pure-Python aggregate-walk helpers (resolve_host_
of_product, collect_decomposed_products) that downstream tool/spatial and
tool/aggregate consumers can call without importing ifcopenshell at module
load.

add_railing_representation now factors into two parts:
* compute_wall_mounted_handrail_geometry returns a pure-geometry
WallMountedHandrailGeometry dataclass (handrail polyline + support
list + terminal caps), no IFC mutation.
* add_railing_representation wraps that dataclass into an
IfcShapeRepresentation as before.
Downstream consumers that want the same math without round-tripping
through an IFC file (Blender gizmo previews, viewport drafts) now
drive compute_X directly. Future add_X_representation work in the
geometry API is encouraged to follow the same shape — a sibling
compute_X function + thin IFC wrapper.
The railing_type parameter is dropped from the signature — only
WALL_MOUNTED_HANDRAIL was ever supported, so the kwarg was dead.
The Bonsai railing-modifier caller is updated in the same commit
to stop passing it; without that update Bonsai's
finish_editing_railing_path raises TypeError on the first edit.
RailingSupport and WallMountedHandrailGeometry use @dataclass(slots=True)
— they're constructed N-per-cap during arc sampling, so the per-instance
overhead matters.

WallMountedHandrailGeometry, compute_wall_mounted_handrail_geometry,

When two GizmoDimension hit regions overlap (a short dimension
nested inside a longer one along the same axis), the larger one
used to win because hit boxes are scaled by world-space length —
the long box fully contains the short one, leaving the short
gizmo unreachable. The larger gizmo stays clickable at its
exposed ends, so smaller-wins is the right UX default.
Sets self.select_bias = -self._dimension_length inside
GizmoDimension.set_dimension_length. The smaller gizmo writes a
less-negative depth value in the GPU select buffer and wins the
tie-break. select_bias is unused elsewhere in the codebase, so
icon and arrow gizmos keep bias=0 and are unaffected (icons
correctly still win against dimensions, since 0 > -length).

set_icon_gizmo_position computed
``mw @ (Translation @ billboard_rot @ Scale)`` — the object's world
matrix was applied AFTER the billboard rotation, so any non-trivial
object rotation (e.g. a wall rotated in plan, a stair rotated to
match a corridor) carried over into the icon's transform and tilted
it edge-on to the camera instead of facing it.
Switch to ``billboarded_at(world_pos, billboard_rot, scale)`` where
``world_pos = mw @ local_pos``: translate to world space first, then
apply the billboard rotation independently of the object's rotation.
This matches the manual pattern the base class's

from ``mw``'s rotation) and that the translation lands at
``world_pos``. Also exercises ``set_icon_gizmo_position`` end-to-end via
a stub gizmo to catch the exact shape of the previously-broken call
site.

Walls gain in-viewport parametric editing matching the door/window/stair
UX: drag handles for length, height, slope (x-angle), layer baseline
cycle, plus cursor-anchored quality-of-life operators (split at cursor,
extend to cursor, extend height, rotate 90, toggle openings) and
two-object state-machine gizmos (unjoin / merge / join-corner /
extend-to-wall / extend-vertically / add-opening).
Wall enters tool.Parametric.EDIT_TYPES, so save-time auto-commit,
GizmoPreferencesWall registration, and the in-progress-edit predicates
all light up automatically through the registry plumbing landed two
commits back.
The three-layer commit model (drag -> BIMWallProperties -> bmesh
preview -> Finish -> single ifc.run) means dragging a handle through
hundreds of intermediate values produces zero extra IFC entities. A
no-op enable->finish round-trip is byte-identical. The snapshot diff
in FinishEditingWall skips unchanged params.
_commit_active_wall_edit_if_any ensures cursor-anchored operators see
committed geometry, not the draft preview box.
Also lands the `prompt_auto_commit_parametric_edits` BoolProperty on
BIM_ADDON_preferences (consumed by the auto-commit dialog landed in
the framework commit) and refactors
`draw_{door,window,stair}_gizmo_parameters` into a shared
`_draw_parametric_gizmo_parameters` helper that the new
`draw_wall_gizmo_parameters` reuses. This commit and the framework
commit are stacked - the framework commit references the BoolProperty
defined here, so they must land together.
Tests cover pure math (core/test_model.py), DimensionGizmoConfig text
formatter, GizmoWallExtendVertically.poll() preconditions, and the
refresh_post_commit cache-invalidation regression. BDD scenarios in
model.feature cover the edit triad, auto-commit on save, and the
two-object gizmos. Documentation added to creating_walls.rst.

Three small post-landing cleanups against the parametric framework commit:
* core/model.py had `are_axes_collinear` and `closest_endpoint_midpoint`
each defined twice — Python silently kept the second copy, the first
was dead code. Removed the dead copies; runtime behavior unchanged
(the live versions were already the kept ones).
* bim/__init__.py's `_parametric_gizmo_preference_classes` docstring
named the wrong link in the import chain (`tool.blender → bim.ifc`).
The real chain is `tool/ifc.py` (and ~6 other tool/* modules) which
import `from bonsai.bim.ifc import IfcStore` at module load. Updated
docstring to cite that root cause and the architectural fix (move
`IfcStore` out of `bim/`).
* tool/blender.py's `from bonsai.bim.ifc import IFC_CONNECTED_TYPE`
carried a 5-line comment claiming it was "lazy" to avoid a circular
load. The import sits inside an `if TYPE_CHECKING:` block with
`from __future__ import annotations` — it never runs at runtime
regardless. Comment removed; the TYPE_CHECKING guard is
self-explanatory.

Establish a single source of truth for parametric element types (door,
window, stair, railing, roof). tool.Parametric.EDIT_TYPES drives:
- BIM<Name>Properties PointerProperty attachment via the registry
- GizmoPreferences<Name> class registration in bim/__init__.py
- save-time auto-commit of pending draft edits
- the refresh_post_commit epilogue called from IfcStore after every IFC
mutation, which fixes the stale-header bug where in-place hotkey
mutations (S_E / C_E) left BIMModelProperties and the gizmo cache
pointing at obsolete values.
Refactors door/window/railing/roof onto shared mixins from
bim/parametric_lifecycle.py (FeatureModifierEditMixin and
PathPreservingEditMixin); stair gets the lock-gizmo refactor and
frame-cache integration. Behavior preserved.
Adds BaseParametricGizmoGroup._prime_frame_caches so the parametric
gizmos stop re-deriving preferences, view direction, and billboard
rotation per frame; reorders poll() to short-circuit on the cheapest

Adds `remove_coplanar_boundary_lines()` to operator.py (Bonsai uses this
path, not draw.py's main()). After `merge_linework_and_add_metadata()`
assigns material CSS classes, this post-processes the SVG to delete
projection line segments that appear in two or more adjacent, coplanar
elements with the same material and presentation style.
Key design decisions:
- Material identity: compared via sorted IFC material ID tuples from
`get_materials()`, not CSS class names — avoids false matches between
unrelated `material-null` elements.
- Presentation style identity: compared via IFC IfcPresentationStyle IDs
from `StyledByItem` on geometry representation items — handles elements
with no material but distinct visual styles.
- Physical adjacency: confirmed by a 3D shared-vertex test (tol=0.01 m)
after a quick AABB guard, rejecting elements whose 2D projections
overlap but sit at different depths.
- Coplanarity: determined by the dominant (largest-area) face normal of
each Blender mesh object — area-weighted averages are unreliable for
slabs whose equal top/bottom faces cancel out. Folded walls sharing an
edge but meeting at an angle are correctly rejected (normal dot ≪ 1.0).

ifcmcp is a new Model Context Protocol server that wraps ifcquery and ifcedit, holding an IFC model in memory across tool calls. It is the preferred way to interact with IFC models from AI assistants and MCP-compatible clients.
Setup:
claude mcp add --transport stdio ifc -- python3 -m ifcmcp
Session tools: ifc_load, ifc_save
Query tools: ifc_summary, ifc_tree, ifc_info, ifc_select, ifc_relations, ifc_clash, ifc_validate, ifc_schedule, ifc_cost, ifc_schema, ifc_contexts, ifc_materials, ifc_plot, ifc_render, ifc_shape, ifc_shape_list, ifc_shape_docs
Edit discovery: ifc_list, ifc_docs
Edit execution: ifc_edit, ifc_quantify
The model stays in memory between calls - ifc_edit does not auto-save; call ifc_save explicitly when done.
Depends on both ifcquery and ifcedit

ifcedit is a new command-line tool for executing ifcopenshell.api mutations from the shell. It wraps the entire API surface — any function callable via ifcopenshell.api can be invoked without writing Python.
Subcommands:
list [module] — list all API modules, or functions within a module
docs <module.function> — full documentation (params, types, descriptions)
run <file> <module.function> [--param value ...] — execute a mutation; overwrites input file by default, or use -o <output> to write elsewhere; --dry-run validates without executing
quantify list — list available QTO rules
quantify run <file> <rule> — run quantity take-off, writing IfcElementQuantity psets back to the file
Parameter coercion: entity references can be passed as step IDs (strings); lists, dicts, booleans, and None are handled automatically.

select <query> — filter elements using ifcopenshell selector syntax
relations <id> — relationships for an element; --traverse up walks to IfcProject
clash <id> — geometric intersection and clearance detection
validate — schema/constraint validation; --rules adds EXPRESS checks
schedule — work schedules with nested task trees

The covering tool used bmesh as an intermediate and relied on
type.assign_type post-listeners (removed in 44a52863a) to generate
the IfcExtrudedAreaSolid body. With those listeners gone, coverings
had no body representation and assign_swept_area_outer_curve crashed.
Build covering representations from scratch using ShapeBuilder, reading
the extrusion depth from the type's IfcMaterialLayerSet. Also replace
bpy.ops.bim.assign_class with bonsai.core.root.assign_class using
should_add_representation=False, consistent with the space fix.
Refactored shared coordinate-conversion and extrusion-building logic
into get_2d_vertices_from_polygon and set_extrusion_representation_from_polygon,
used by both space and covering code paths. Removed all bmesh-dependent
dead code from the spatial tool.

Space regeneration was only updating the Blender mesh and marking the
object as edited, but the IFC representation was never synced on save.
Replace the bmesh-based approach with ShapeBuilder to write geometry
directly to IFC as an IfcExtrudedAreaSolid, then reload via
switch_representation. This applies to both new space creation and
existing space regeneration.
Also changes assign_ifcspace_class_to_obj to call
bonsai.core.root.assign_class directly with
should_add_representation=False instead of bpy.ops.bim.assign_class.

After assigning an IFC class and undoing, msgbus subscriptions registered
with the old Python object wrapper survived (PERSISTENT flag) but could
not be cleared because: (1) rollback_link_element looked up objects by
their post-link name which no longer exists after undo, and (2) the
per-object clear_by_owner calls in rebuild_element_maps used new Python
wrappers that didn't match the old subscription owners.
Fix by using a dedicated stable object (object_subscription_owner) as
the msgbus owner for all per-object subscriptions, allowing
rebuild_element_maps to clear all stale subscriptions in one call
regardless of Python wrapper identity changes during undo/redo.

Blender doesn't have it's own quick favorites manager and working with them can be not very flexible - you can add them in context menu and remove them from Quick Favorites menu. But you can't reorder them, you can't rename them and you can't even add a new button to favorites if it's not added by some addon in the UI.
Have been stumbling upon this for awhile and decided to create an experimental manager UI for this. Things it can do:
- help user create a button with any operator in Blender and properties they prefer to then save it Quick Favorites. Which seems can be very useful in Bonsai, since you can create separate buttons for all kinds of selectors expressions, class assignment or other operators.
- it can import quick favorites from user's actual current quick favorites, so they can just modify them a bit, reorder, rename and then add them again.
- Since quick favorites are not exposed to Python API in Blender, we're using a very hacky way to retrieve them from Blender and don't provide our own buttons for adding and removing quick favorites, as it may be dangerous and even more hacky in implementation. So the workflow for user is to either generate some buttons and add them to quick favorites using Manager or to import it's own quick favorites, then change them how they like, then remove quick favorites using usual quick favorites menu and then add new button one by one.

* docs: add BonsaiPR bleeding edge installation section
Add new section to installation.rst documenting the BonsaiPR
community build, including why it exists, how the automated
PR-merging system works, installation steps with automated
updates, manual installation, and the PR workflow for
contributors.

* whoops
Linking flags were missing for `MODULE` type libraries, example warning: `IfcPythonPYTHON_wrap.obj : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance`
Which is useful when debugging and calling tools.ps1 directly - less thing to modify to make it work.
Also replaced `exit 0` with `return`, so it would be possible to reuse functions inside `tools.ps1`
To avoid running in a situation when some builds are using one tag and some are using another and then unstable repo script fails to find builds for some platforms.
