Fix#8122: Guard get_sheet_references against a missing document reference.
Guard remove_drawing against a missing document association to skip
the document/file cleanup steps. Fall back to direct entity removal
when the drawing's group association is also missing, so the IFC
entity is purged and the Drawings panel refreshes correctly.

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.

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.

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.

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.

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:

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.

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,

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.

* 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.

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

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
behaviour into its own service).

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).
Adds test/bim/module/drawing/test_dimension_gizmo_priority.py

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
``update_editing_gizmos`` already uses for validate/cancel/cycle for
exactly this reason.
Drops the now-stale workaround docstring on
``GizmoWallEdition._update_icon_row_extras`` that documented why it
bypassed ``set_icon_gizmo_position`` — the helper does the right
thing now.
Adds ``test/bim/module/model/test_stair_gizmos.py`` as the regression
guard: parametrised over six rotation angles, asserts that the rotation
part of the resulting matrix equals ``billboard_rot`` (no contribution
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,

- 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.

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

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.

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

Space regeneration was only updating the Blender mesh and marking the

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.

The API no longer modifies Items — callers manage this explicitly.
validate_type and Bonsai's AddBoolean operator now handle their own
item removal scoped to the correct representation.

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.

* 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.
Objects with hide_select=True could not be selected during
isolation, causing hide_view_set to incorrectly hide them.
Objects with hide_viewport=True had their H-key hide state

Fix Sphinx docs: replace csv-table with list-table for formatting functions
The documentation table of formatting/query functions was not rendering
because `.. csv-table::` requires strict RFC4180 CSV escaping. The table
contains nested quotes, inch marks (e.g. `3' - 0"`), backticks, and code
examples, which cause the CSV parser in docutils to treat rows as malformed
and drop the entire directive.
Replaced the directive with `.. list-table::`, which parses reStructuredText
instead of CSV and safely supports inline code, quotes, and multi-line cells.
Also moved the examples text outside the directive block and ensured a blank
line after the table so Sphinx does not interpret following paragraphs as
table rows.
No content changes — documentation now renders correctly.

Guidelines for external contributors using AI coding tools,
covering licensing, AI disclosure requirements, PR scope,
commit style, code formatting, and testing expectations.
Generated with the assistance of an AI coding tool.
Previously, there was a dance between invoke, execute, and draw. This
can probably be resolved, but is a high-risk for undo bugs. This
simplifies the logic flow to just a traditional _invoke -> _execute.
I add a new feature test to at least make sure it does something, and
this also fixes the segfault in tool tests as it no longer requires the
launching of the file browser.
In my previous commit, I mistakenly believed that there was an API change from
snap_angle_increment to snap_angle_increment_3d
But since the feature was introduced in blender 4.2 the setting is called
snap_angle_increment_3d.
Previously it was implemented inline. This now implements it as a
tool.Blender function with tests. Also the previous tests didn't
actually run and weren't actually testing any tools despite being in a
tool tests.
IfcSectionedSurface and IfcSectionedSolidHorizontal both of CrossSectionPositions attributes which are lists of IfcAxis2PlacementLinear. The implementation of each class used its own bespoke mapping of IfcAxis2PlacementLinear, which were identical to each other and slightly different than IfcAxis2PlacementLinear. Now the two sectioned classes use the one and only mapping for IfcAxis2PlacementLinear
* Linked IFC projects enhancement (multiple links to same project file)
- Implement link management system using UUIDs as identifiers to support multiple links to the same IFC file
- Add georeferencing compatibility detection and UI display (NONE, NOT_COMPATIBLE, PARTIAL_COMPATIBLE, FULL_COMPATIBLE)
- Support for duplicate link creation with Shift+D shortcut and automatic position offset
- Add false origin and project north calculation from 3D cursor for MANUAL mode
- Only store one cache per file, regardless of the amount of links
- Prevent duplicate links based on filepath and position comparison
- Improve error handling for missing files and loading failures
- Update tests
* Remove duplicate georef UI
I try to avoid duplicate UI (especially for one that can be as
sophisticated as georef - e.g. missing is WCS) as it means double the
code, double the tests, potential user confusion. BTW the note about
vertical datum isn't quite accurate as it may be included in the CRS
definition so vertical datum is optional.
* Remove depsgraph_update_post handler for update_link_ui_on_transform as per core developer feedback
* Move get_projected_crs to geolocation module
* Refactor get_projected_crs to simplify as per core developer feedback
* Remove unused import of bonsai.tool from project module
* Use IfcDocumentInformation per linked file and IfcDocumentReference for locaiton information
* Refactor SaveBlendMetadataFile operator to remove try-except blocks and remove linked projects collections since they are recreated by bonsai
* Cleanup removing empty collection instances for linked models in metadata.blend file and call determine_georeferencing_compatibility on link reload
* Add locking mechanism for linked models and update UI to reflect lock status
* Update logic that track IFC to execute_ifc_duplicate_operator instead of having it in execute() which does not track IFC undo/redo
* Refactor link handling to use get_link_empty_handle and set_link_empty_handle methods which in turn use the standard blender-ifc integrations patters (tool.Ifc.get_object(doc_reference) and tool.Ifc.link(doc_reference, empty_handle)
* remove operator.DuplicateLink and move it to tool.Project.duplicate_link()
* Refactor link handling to use sequential identifiers (no need for STEP ID DocRef)
* Refactor IFC linking logic to handle cases without a parent IFC file loaded. Firts link flase origin becomes parent origin
* Lock should not affect selection.
This makes it consistent with grid / spatial lock, and also toggle
selectability is already implemented.
* Remove unnecessary check for loaded library as Blender seems to do this internally already
* Rename util to get_crs because in IFC4X3 you can also have geographic CRS not just projected
* Remove unnecessary call to determine_georeferencing_compatibility
This function is already always called prior to calculate_link_position
so shouldn't be called here. It's also a very expensive function: as it
currently stands, just to link a single IFC, ifcopenshell.open() is
called 3 times. This reduces it to 2.
* Store CRS as metadata for linked models, and compare metadata when indicating georeferencing compatibility
Previously, to check georeferencing compatibility, ifcopenshell.open()
was used. When linking large models, this adds considerable time and
memory usage. This instead captures the georef as standard metadata in
our .cache.json. This now reduces the ifcopenshell.open() calls back
down to only 1 as necessary (see previous commit).
* Use link index instead of link name to fetch link collection item
Link name runs into issues with name uniqueness. This is why you created
a function for "get next link ID". After this refactoring, we can no
longer worry about uniqueness and that function may be removed.
* Simplify reloadlink into just unload and reload (with cache disabled)
This function should not be responsible for editing any data.
* Remove unnecessary get_next_link_id as names no longer need uniqueness
This now frees up the name variable to track a more meaningful, human
name like IfcDocumentInformation's Name attribute.
* Rewrite get / set link_empty_handle to just use the link directly
This prevents needless logic to fetch the link and also removes issues
related to duplicate names.
* Temporarily remove logic in prop callback
Right now, pretty much all the logic is done in a prop callback. In
general logic in prop callbacks should be minimised, since it's hard to
test and easily triggered as a domino effect of another change, and may
also impact undo/redo.
* Remove code that unnecessarily removes cache
This code removes cache, which means any project unlinking an IFC auto
clears the cache for any other project which doesn't make sense, and
also breaks the ability to readd it quickly.
* Rewrite link, unlink, load, and unload IFC
There were a few issues tackled here:
- Operators that change any IFC data must use tool.Ifc.Operator and
_execute, otherwise undo/redo will break. That's one of the risks of
using prop callbacks, as it is not explicit when an IFC edit happens.
- The usage of IfcDocumentReference was not correct. The Location
should store the URL, _not_ the position. The position should be in the
Identification attribute.
- The URL was stored in IfcDocumentInformation location, which does not
work in IFC2X3. There are a few changes here to make it IFC2X3
compatible.
- Generally move logic in operators, not prop callback.
* Remove restriction around manual mode.
Users should be able to use manual mode if they want.
* Restore AUTOMATIC mode to identical behaviour to file open
This is the first step to reusing cache files agnostic of the host.
* Revert tests for a fresh start for updating tests
* Revert "test_feature - clean up .ifc.cache. files after test was executed"
This reverts commit 99ae768ddf.
* Update tests and reimplement calculations for matrix of empty handle
Previously, the empty would always be placed at the origin, unless a
"position" offset was present. This is a problem, because the "position"
is simply a local offset relative to the Blender cache! If the cache was
regenerated, the offsets would be outdated. Also, the cache appeared in
different locations depending on the false origin mode, so the offset
would mean different things to different people.
Instead, a more robust method is:
1. When you link a file, a Blender cache is generated. The Blender
origin of this cache is arbitrary! It depends on the user's false origin
mode and is purely a Blender session specific thing.
2. When you load a link, a link is _always_ loaded into the correct
location with regards to IFC global coordinates. All math is done from
the perspective of IFC.
3. If you choose to transform (move / rotate / scale!?) this link from
its correct location, that gets recorded as a 4x4 transformation matrix.
Note: I haven't implemented this properly yet.
Tests all pass, with a minor modification to the new behaviour that
false origin mode now won't affect the location it ends up in, only the
generation of the cache.
* Remove arbitrary convention around display name
Not needed anymore now that A/M/D is a detail and not significant on
actual coordinates, and also that the UUID is no longer needed.
* Simplify implementation of loading linked models when opening an IFC
* Move link matrix calculation from operator to tool for reuse
* Implement editing link location and calculation of transformation matrix
I changed my mind on the is_locked thing, since it isn't clear to the
user that locking need to be done to save changes.
* Remove old is_locked, prop update callback no longer needed (dedicated operator instead), remove old calculation code
* Simplify code related to placed_as_per_georef
* For now, simple skip for duplicate / delete
IMO duplicate / delete / move a link are very rare and explicit
operations.
* Update tests
* Remove host_model coordinate data as cache is no longer host model dependent
* Move icons outside list because there are too many
* Minor tweaks
