convert_openings groups openings with similar minimal edge lengths into a
single multi-tool BOPAlgo_CUT (batching introduced in 7c1071f588 for
robustness and speed on the common case). On the file attached to #487
one such batch of 3 openings fails the interference checks at every
fuzziness the retry ladder is allowed to attempt, because the ladder
rightly refuses to raise fuzziness past the smallest real edge length of
the 20mm recess operand, and the whole batch is dropped, leaving the wall
uncut. Each of those openings subtracts cleanly when cut on its own.
This adds a gated last resort in boolean_operation: only after a
multi-tool CUT has exhausted every fuzziness attempt, reattempt it by
applying the same tool operands one at a time, each cut feeding the next.
The batched path stays the default; single-tool cuts and non-CUT
operations are unaffected, and the fallback is all-or-nothing so a
partial sequential success never silently replaces the operand.

angle_round_threshold was only assigned inside the `distance > 0`
branch of calculate_distance_and_angle, but read unconditionally
whenever should_round is True. When the mouse sample coincides with
the last placed point (distance == 0), such as the first mouse move
after placing a wall's start point on a YZ plane view, this crashed
the modal wall tool.
angle_round_threshold is a fixed cutoff unrelated to whether distance
is currently zero, so it is now assigned once before the branch.

Browsers were caching /static/js and /static/css for the standalone
webui (costing, gantt, drawings, index, demo pages) indefinitely, so a
shipped JS fix (e.g. the Download CSV button) would only reach a user
after a manual hard refresh.
Two changes, applied consistently across all five webui pages.
1. Every locally served link/script tag in the pystache templates now
carries a ?v=<bonsai version> query string, falling back to a static
asset mtime hash when BONSAI_VERSION isn't set (e.g. running
sioserver.py standalone). Since get_bonsai_version() includes the
build's commit hash, the token changes on every shipped update.
2. Responses under /static/ and /jsgantt/ now carry
Cache-Control: no-cache, must-revalidate. This covers what query
stamping alone can't reach: cost.js and gantt.js statically import
utilities/costui.js by a fixed relative path with no query string, so
that nested module still needed server side revalidation to pick up
changes.
Verified against a live aiohttp instance of sioserver.py: rendered
HTML for all five routes shows the stamped URLs, and the token
changes when BONSAI_VERSION changes between two server runs. A
conditional GET against a static file with a stale If-Modified-Since
header confirms the cheap 304 revalidation path still works.
Also used this instance plus a real headless Chromium (Playwright) to
click test the previously untested Download CSV button on the costing
page. The ribbon renders it correctly, and clicking it (with a
synthetic cost-items table injected into the DOM to stand in for a
connected Blender's data) triggers a real Blob download with the
correct filename and CSV content. No bug found, the button works as
intended.

Stefano's final ask on #6251 was specific: the ODS/XLSX export should
show exactly what the cost panel shows, ID (Identification), Name,
Quantity, Value, Total Cost, no more, no less. The previous fix in
this PR removed the internal bookkeeping columns but still exported
Description, Unit and a per-category cost breakdown (Labor Cost,
Material Cost, etc), none of which appear in the panel.
Presentation formats (.ods/.xlsx) now use an explicit allow-list of
columns instead of a block-list of internal ones, and relabel headers
to match the panel's own wording (ID / Value / Total Cost). The .csv
format is unchanged: csv2ifc still reads back the extra bookkeeping
columns for the import round trip, which is why it keeps them.
Also add a "Download CSV" button to the browser costing view
(Generate spreadsheet browser), which previously only offered a
clipboard-based Copy Selected. It reuses the already-rendered table
(respecting the user's column visibility settings) and triggers a
real file download, dropping only the UI-only Actions column.
AI-generated with Claude Code; reviewed and tested by Petru Conduraru.
Three defects reported against the Costing tab export:
1. XLSX export crashed with ModuleNotFoundError: xlsxwriter was never
bundled with Bonsai. Port the writer to openpyxl, which ifccsv
already uses and Bonsai already ships, so it works out of the box.
2. Every ODS cell was written as a string (numbers as text), and the
formula branch was dead code: it compared against 'Total Price' /
'Rate Subtotal' while the headers are 'TotalPrice' / 'RateSubtotal'.
Numeric columns are now typed float cells and TotalPrice becomes a
real formula: Quantity*RateSubtotal on leaf items, SUM over the
direct children's TotalPrice cells on sum items.
3. Internal bookkeeping columns (Id, ItemIsASum, Hierarchy, Index,
Quantities) leaked into the presentation formats. ODS/XLSX now hide
them; CSV keeps them since csv2ifc consumes them for the round trip.

get_element_value could not reach the members of an IfcPhysicalComplexQuantity
(or IfcComplexProperty) by their natural path. util.element expands a complex
quantity into a dict whose nested members live under a "properties" sub-dict,
but the selector's dict navigation only looked at the top level, so
"Qto_Custom.Layer1.Width" returned None and IfcCsv exported nothing for it.
Only the internal "Qto_Custom.Layer1.properties.Width" path worked.
When a key is not a direct member of the value dict, descend into its
"properties" sub-dict so nested quantities/properties resolve with the
natural "Set.Complex.Nested" path. Direct keys still take priority, so the
explicit ".properties." path stays backward compatible and the regex branch
is untouched.
Verified: Qto_Custom.Layer1.Width -> 0.1 and Layer1.Height -> 2.5 (were
None), the sibling simple NetArea still resolves, the legacy .properties.
path still works, and IfcCsv now exports the nested value. test_selector.py:
38 passed (adds test_selecting_a_nested_complex_quantity).

* Fix ci-bonsai-daily: ProjectLibraryData duplicate parent-library enum
parent_libraries_enum() adds an explicit entry for get_root_context(),
then loops over cls.data["project_libraries"] (all IfcProjectLibrary
entities) and appends each. For a library-only file (no IfcProject),
get_root_context falls back to the top-level IfcProjectLibrary itself,
so the root is appended twice with the same enum key (its STEP id),
which Blender EnumProperty requires to be unique -> the data load
asserts. Normal project files are unaffected (root is an IfcProject
whose id never collides with a library id).
Skip library_id == root.id() in the loop (dedup by id, the colliding
key). Verified in headless Blender:
test_project_library_data.py::TestLibraryOnlyFile goes from 1 failed /
5 passed to 6 passed.

* Bonsai: repair library files missing the required IfcProject, not just the symptom
Per the IFC Project Context concept template, every project data set (library
files included) shall contain exactly one IfcProject, and IfcProjectLibrary
instances are assigned to it via IfcRelDeclares. There is no such thing as a
spec-valid file rooted on IfcProjectLibrary alone.
get_root_context() (added in 260a387069, #8184) treated a missing IfcProject
as license to use the top-level IfcProjectLibrary as the file's root context
instead. That invalid premise is why project_libraries() (which walks every
IfcProjectLibrary, root included) then re-added that same entity, producing
the duplicate, colliding enum key this PR originally papered over with a
dedup guard.
Add tool.Project.ensure_project_context(), which repairs a file missing
IfcProject by creating one and declaring the file's root-level
IfcProjectLibrary instances to it, and tool.Project.open_library_file(),
which opens a library file through that repair. Route all three
IfcStore.library_file load sites in SelectLibraryFile through it. Downstream
code (get_root_context, ProjectLibraryData, RefreshLibrary,
AddProjectLibrary) now always operates on a spec-valid model, so the
duplicate enum entry cannot occur; the previous one-line dedup guard in
parent_libraries_enum() is kept only as cheap defense in depth for callers
that bypass the load-time repair, not as the fix.
Rework test_project_library_data.py: the previous _make_library_only_file()
fixture built an invalid library-only model and asserted that as correct
behaviour. Replace it with a spec-valid fixture (IfcProject + IfcProjectLibrary
declared to it) for the downstream tests, and a malformed fixture used only to
exercise the new repair path.
Verified live in headless Blender (isolated profile): reproduced the original
duplicate-enum-key failure mode, then confirmed ensure_project_context/
open_library_file repair a malformed file and ProjectLibraryData,
refresh_library and add_project_library all operate correctly on the result,
with no duplicate keys and no regression on already-valid files or IFC2X3.
This change was made with the assistance of an AI tool.
* Bonsai: stop supporting library-only files, do not repair them
Per Moult's feedback: if the IFC is invalid, our default position is to not
support it, not to patch around it. A library file with no IfcProject is
invalid IFC (Project Context concept template requires exactly one
IfcProject), and it is not ubiquitous: every library file bonsai ships under
bim/data/libraries has an IfcProject with the IfcProjectLibrary declared to
it via IfcRelDeclares. The single #8183 report is an outlier, not a common
authoring pattern worth accommodating.
Remove tool.Project.ensure_project_context() and open_library_file() (the
load-time repair added in the previous commit here) and revert
SelectLibraryFile's three load sites to plain ifcopenshell.open. Simplify
get_root_context() back to returning ifc_file.by_type("IfcProject")[0]
directly, no IfcProjectLibrary fallback: a file without IfcProject now raises
IndexError instead of being silently treated as valid. AddProjectLibrary's
nest-under-library branch is now dead code (root_context is always an
IfcProject) and is removed. The one-line enum dedup guard from the original
commit here is also removed: since get_root_context can only return an
IfcProject or raise, an IfcProject id can never collide with a library id, so
the guard has nothing left to guard against.
Rework test_project_library_data.py: drop the invalid _make_library_only_file
fixture and its tests, which asserted an unsupported model as correct
behaviour. Replace with a single spec-valid fixture matching bonsai's own
shipped library files (IfcProject + IfcProjectLibrary declared to it), used
for the ci-bonsai-daily regression test and the refresh/add-library
operators, plus one explicit test that get_root_context raises for a file
without IfcProject, documenting that this input is intentionally
unsupported rather than silently tolerated.
Verified live in headless Blender (isolated profile, source-loaded, never
the real profile): confirmed the removed methods are gone, that a
library-only file now raises instead of being handled, that
ProjectLibraryData/refresh_library/add_project_library all work correctly
on a spec-valid model with unique enum keys, and spot-checked that every
library file under bim/data/libraries already has an IfcProject.
This change was made with the assistance of an AI tool.
* Bonsai: inline get_root_context, trim docstrings, confirm get_parent_library unchanged
Per Moult's round 3 review. get_root_context added nothing over
ifc_file.by_type("IfcProject")[0], which is guaranteed by the IFC Project
Context concept template; remove it and inline the call at its three sites
(operator.py's RefreshLibrary and AddProjectLibrary, data.py's
parent_libraries_enum). Trim the get_parent_library docstring to one line;
its logic is untouched by this PR, byte for byte identical to origin/v0.8.0,
and still returns None only when project_library has neither Nests nor
HasContext, never for a library declared directly to IfcProject.
Rework test_project_library_data.py to match: replace the two
get_root_context-specific tests with one that exercises the real call site
(ProjectLibraryData.parent_libraries_enum raising IndexError for a file
without IfcProject), and add an explicit test that get_parent_library
returns None for a genuinely orphaned library. Also drop a long inline
comment that restated what the test body already shows.
Verified live in headless Blender (isolated profile, source-loaded, never
the real profile): all 17 test/bim/module/project tests pass, including the
new get_parent_library None-for-orphan case. Ran the full test/bim suite
before and after on the identical harness: 82 failed/1335 passed both times,
same failing tests (all pre-existing, unrelated to this module).
This change was made with the assistance of an AI tool.
* Bonsai: fix EditProjectLibrary leaving stale declarations after reparenting
Per Moult's round 4 review. The assertion change (get_parent_library(root)
now returns the IfcProject instead of None) is correct: in the old
library-only test model a top-level library had neither IfcRelNests nor
IfcRelDeclares, so None meant "top level". In the new spec-valid model a
top-level library is always declared to the guaranteed IfcProject via
IfcRelDeclares, so get_parent_library correctly resolves it through the
HasContext branch instead of falling through to None. get_project_hierarchy
already keys top-level libraries under the project for exactly this reason,
so the library tree still renders correctly.
Auditing every caller found one real bug in EditProjectLibrary, which
Gorgious56 originally wrote for the library-only model. Its move-library
logic assumed a top-level library (previous_parent_library is None) needed
no cleanup before nesting it under a new parent, and that unnesting a
library back to the project needed no new relationship because it was
"already assigned by default". Both assumptions relied on a top-level
library never actually holding a IfcRelDeclares, which is no longer true.
Reproduced live: moving a project-declared library under another library
left its old IfcRelDeclares dangling alongside the new IfcRelNests (an
invalid double parentage), and moving a nested library back to the project
left it with neither relationship, orphaning it out of the tree entirely.
Fixed by tearing down whichever of IfcRelDeclares/IfcRelNests the library
previously had before establishing whichever one the new parent requires,
instead of assuming which prior state applies.
Added tests: get_parent_library resolving a nested sub-library to its
library parent (the third contract case alongside project-declared and
orphaned), and both EditProjectLibrary reparenting directions, which fail
without the operator.py fix and pass with it.
Verified live in headless Blender (isolated profile, source-loaded, never
the real profile): all 20 test/bim/module/project tests pass. Ran the full
test/bim suite before and after on the identical harness: 123 failed/1294
passed before, 123 failed/1297 passed after, identical failing test names
in both runs (diffed), the extra 3 passes are the new tests above.

Link IFC with 'Use Cache' unchecked crashed with FileNotFoundError

35e3d9c42, which refactored the cache-clear guard from
'if not self.use_cache and blend_filepath.exists()' into
should_clear_cache() but dropped the existence check on the
not-use_cache path, so os.remove() ran on a non-existent file.

remove is never attempted when there is nothing to clear, while
keeping the query-mismatch cache invalidation intact.

compare() recursed into list values passing the negated comparison through,
so != meant "at least one item differs" and both = and != matched the same
elements on any multi-valued property (e.g. an enumerated property with two

the aggregate instead, so != means "no item equals" and stays the complement
of =. The same applies to !*=.

The Optimise recipe imported `toposort`, a third-party PyPI package that
is not bundled with Bonsai, so running the recipe there raised
`ModuleNotFoundError: No module named 'toposort'`.
Replace it with the standard library `graphlib.TopologicalSorter`
(available since Python 3.9), which provides the same dependencies-first
ordering guarantee the recipe relies on: forward-referenced instances are
mapped before the instances that reference them. The dependency-graph
dict format ({node: {predecessors}}) is identical between the two, so the
graph construction is unchanged. Drop `toposort` from ifcpatch's
dependencies since it is no longer used.
Verified with toposort NOT installed: the Optimise recipe now runs and
deduplicates correctly (IfcParseExamples_test.ifc 88 -> 63 instances, all
6 products preserved, output reopens cleanly).

tool.Bsdd.identifier_url() (pset/ui.py pset name check in the Property
Sets panel) reads client.baseurl unconditionally, but the test stub
never had that attribute, so any scenario that opens the Property Sets
panel dies with AttributeError under the stub. The boolean.feature
scenarios only surfaced this once their STEP id failures were fixed,
the id failure had been masking it. Mirror the real bsdd.Client
default so identifier_url() resolves to the standard identifier URL.
This change was made with the assistance of an AI tool.
The two boolean.feature scenarios pinned representation item objects by
absolute STEP id (Item/IfcHalfSpaceSolid/90, the BBIM_Boolean pset text
[91]). Those ids shift every time any earlier entity allocation in an
empty project changes (latest instance: #8577 moved 90 to 86), so this
cluster re-breaks on unrelated commits.
Make the object-name and panel-text BDD steps run their argument through
replace_variables, the same substitution 'the variable' and the
connection steps already use, and have boolean.feature capture the real
ids from the IFC file (by_type(...)[0].id()) into variables at the point
the entities are created. The steps stay strict: the substituted name
must still resolve to exactly the named object, there is no wildcard
matching. Substitution is a no-op for every existing feature string
without a {variable} placeholder.

Two independent test-harness/fixture defects in test/bim/test_feature.py:
- OperatorSpy had no bl_rna, so any BDD step that redraws a panel calling
helper.draw_filter() (which tests "module" in op.bl_rna.properties)
crashed with AttributeError. Give OperatorSpy a bl_rna property that
forwards to the real registered operator class
(bpy.types[bl_idname].bl_rna), matching live UILayout.operator()
semantics. Fixes test_select_all_walls and test_edit_filter_query.
- The shared "I create default MEP types" step looked up
bpy.data.objects["IfcDistributionPort/Port"], but port creation never
sets port.Name, so tool.Loader.get_name deterministically names the
object "IfcDistributionPort/Unnamed". Update the literal. Fixes the MEP
scenarios (connect/transition/bend) that share this setup.
Verified in headless Blender: OperatorSpy scenarios 2 passed (were
AttributeError); MEP test_connect_mep_elements* go from
KeyError 'IfcDistributionPort/Port' to passing.

Per aothms's review comment: this file's schema was already changed
independently on v0.8.0 since this branch was created, so this PR's own
edit conflicts with it. Reverting to the current upstream version of the
fixture; the bsdd.py rate-limiting fix is untouched.
bsdd.py: the Client made every request with a bare requests.get, so a single
429 from the (unauthenticated, aggressively rate limited) bSDD API failed the
whole test. Route requests through a Session with a mounted urllib3 Retry
(5 attempts, backoff, honouring Retry-After) for 429/5xx, matching how a
resilient API client should behave, not just papering over the test.
ColumnPSetsOfSets.ifc: FILE_SCHEMA was accidentally changed from IFC4X3_ADD2
to IFC2X3 in a7738eeb64 (an unrelated logger refactor), a one line collateral
edit to this fixture. The file's DATA section still uses IFCPROPERTYSETDEFINITIONSET,
an IFC4+ only type. Parsing it against IFC2X3 threw "Entity ... not found in
schema", which silently fell back to interpreting the value as a raw nested
aggregate instead of the intended defined-type wrapper, producing the
double-nested tuple that broke test_stream, test_file and test_rocks in
test_streaming_rocksdb_and_simpletyperefs.py. Restoring the original schema
declared when the fixture was added (ff3fa48332) fixes all three.

The choco dir was renamed from choco/blenderbim to choco/bonsai back in
2024 (Rename choco dir), but choco_release.py's BLENDERBIM_DIR constant
was never updated, so the daily choco release job crashes immediately
with FileNotFoundError trying to os.chdir into the now nonexistent
choco/blenderbim directory.
Release tags also moved from a bare blenderbim-YYMMDD scheme to
bonsai-X.Y.Z-alphaYYMMDDHHMM, so the tag-prefix strip used to build the
package version still looked for the old "blenderbim-" prefix and left
it untouched, embedding the raw tag (including the already-present
"-alpha" segment) into the nuspec version field, which the template
then doubled up with its own "-alpha" suffix, producing an invalid
NuGet version string. Both are fixed together since the second bug
would otherwise surface as soon as the first one is unblocked.
The pre-commit black hook also reformatted pre-existing whitespace
drift in choco_release.py (this file sits outside CI's lint scope, so
it had never been auto-formatted before); that reformatting is
incidental to satisfying the local hook, not part of the fix itself.

replace_attribute() rewrites references inside aggregate attributes via
element.walk(), but never checked whether the replacement value was
already present elsewhere in the same aggregate. For an EXPRESS SET
(e.g. IfcProject.RepresentationContexts, IfcRelAggregates.RelatedObjects)
this can leave the same reference listed twice, which is invalid IFC.
LIST and BAG aggregates legitimately allow duplicates, so a blanket dedup
would be wrong; only SET-typed attributes are deduplicated, determined at
runtime from the schema declaration (IfcOpenShell#8706 review comment).
The SET/LIST/BAG check is cached per (schema, class, attribute index), and
the dedup pass itself only runs when a cheap linear pre-check finds the
replacement value already present in the aggregate, so the common case
(no duplicate produced) pays only that pre-check, not a hash-set rebuild.
Benchmarked against a 23MB (431k entities) and a 104MB (2.4M entities) IFC
model against a large SET attribute: worst case adds well under 1ms per
call; the realistic case (merging duplicate contexts, matching the PR
#8706 scenario) shows no measurable regression.

assign_cost_item_quantity skipped every IfcSpatialElement, which also
swallowed IfcSpace. Spaces are legitimate quantifiable objects, so their
Qto_SpaceBaseQuantities (for example GrossFloorArea) were never picked up
and count based cost items fell back to 0. Keep skipping spatial
containers (site, building, storey) but allow IfcSpace.

The headless "IfcOpenShell" calculator had all Qto_SpaceBaseQuantities
formulas set to null for IfcSpace in both IFC4QtoBaseQuantities.json and
IFC4X3QtoBaseQuantities.json, so qto.py's `if not formula: continue`
skipped every quantity, no geometry task was queued, and spaces never
appeared in results (elements_quantified: 0). The Blender calculator
already computes these; they were just never ported to the
ifcopenshell.util.shape-backed calculator.
Map the eight computable quantities to existing util.shape functions,
mirroring the Blender calculator semantics (no new shape.py code):
GrossFloorArea=gross_get_footprint_area, NetFloorArea=net_get_footprint_area,
GrossCeilingArea=gross_get_top_area, NetCeilingArea=net_get_top_area,
GrossPerimeter=gross_get_footprint_perimeter, GrossVolume=gross_get_volume,
NetVolume=net_get_volume, Height=net_get_z.
Left null (matching the Blender ruleset, not guessed): GrossWallArea,
NetWallArea, NetPerimeter (Blender stub), and FinishFloor/CeilingHeight

which this per-element calculator architecture can't reach).

and the formula->function resolution is schema-agnostic.

The ifc5d IfcOpenShell (geometry-based) Qto engine computed
Qto_CoveringBaseQuantities using axis-agnostic heuristics:
- GrossArea/NetArea: gross_get_max_side_area / net_get_max_side_area,
the largest of the X/Y/Z projected side areas.
- Width: gross_get_min_xyz, the smallest of the X/Y/Z dimensions.
The Blender Qto engine instead already used
EPset_Parametric.LayerSetDirection (AXIS2 for wall-like coverings,
AXIS3 for floor/ceiling-like coverings) to pick the correct axis via
get_covering_gross_area/get_covering_net_area/get_covering_width in
bonsai/bim/module/qto/calculator.py.
For any covering whose length isn't the largest dimension (e.g. a
short wall-covering strip, or a small covering patch), the two
engines' heuristics can pick different faces/axes entirely, giving
different Width/Area values for the same element - this is what was
reported in #6728.
Fix: give the IfcOpenShell engine the same layer-set-direction
awareness. Added IfcOpenShell.get_covering_parametric_axis/
get_covering_area/get_covering_width (dispatched as internal
functions, like the existing get_weight/get_segment_length), and
wired gross_get_covering_area/net_get_covering_area/
gross_get_covering_width into the IfcCovering rules in
IFC4QtoBaseQuantities.json and IFC4X3QtoBaseQuantities.json.
The AXIS2 area/width formulas (get_side_area, net_get_y) intentionally
match the simpler formulas already used for Qto_WallBaseQuantities in
this same rule set (net_get_side_area/net_get_y), rather than
replicating the Blender engine's more elaborate get_lateral_area/
get_width (min(X,Y)) helpers, consistent with how the two engines
already diverge for regular walls without being considered a bug.
Verified with a standalone script driving ifc5d.qto.IfcOpenShell
directly against synthetic AXIS2/AXIS3 IfcCovering geometry: for
typical proportions old and new formulas agree, and for
disproportionate coverings (thin dimension not the smallest/largest)
the old formulas picked the wrong axis while the new ones correctly
track the covering's LayerSetDirection, matching the Blender engine.
Did not verify through the full Blender/Bonsai UI, as it would have
required registering the addon in the machine's shared Blender
profile, which is unsafe while other agents may have it loaded.

copy_cost_item appends the copy to the inverse relationships of the
original cost item, which for a root cost item includes the source
schedule's IfcRelAssignsToControl. copy_cost_schedule then assigned that
same cost item to the new schedule as well, so the copies showed up in
both schedules and deleting them from one removed them from the other.
Unassign the copy from the source schedule before assigning it to the
new one.

Fixes#4443. The Wall/Slab/other authoring tools (BimTool subclasses)
already bind Shift+Q to bim.perform_quantity_take_off via hotkey_S_Q,
but the Spatial tool has its own separate keymap/operator
(bim.spatial_hotkey) that never registered a Q entry, forcing users to
switch tools just to (re)calculate quantities for a selected element.
Added the same Shift+Q keymap entry and a matching hotkey_S_Q handler
to the Spatial tool, mirroring BimTool's existing behavior exactly
(including the same selected-objects guard).
The other part of the request, a bulk "calculate all quantities"
entry point, already exists today: bim.perform_quantity_take_off
computes quantities for every IfcElement when no objects are
selected, exposed via the Scene > Quantity Take-off panel regardless
of which workspace tool is active, so no change was needed there.

can_nest() only permitted IfcElement-to-IfcElement pairs, so nesting
two IfcElementType objects (e.g. an IfcElementAssemblyType nesting a
component IfcDoorType) was silently rejected. IfcRelNests.RelatingObject/
RelatedObjects are typed as the general IfcObjectDefinition in the
schema, so type-to-type nesting is schema legal, IfcOpenShell's core
nest.assign_object API already handles it generically, and the Nest
UI panel is driven purely by ifcopenshell.util.element.get_nest/
get_components (IFC data queries, not Blender collection structure),
so once the relationship exists it displays correctly with no other
changes needed.
Extended is_compatible_class to also accept a same-kind IfcTypeProduct
pair. Mixing an occurrence element with a type is intentionally still
rejected, that isn't a real modeling pattern.
Verified live in headless Blender: type-to-type nesting now creates
a real IfcRelNests and the Nest panel's own data functions reflect
it correctly; mixing an occurrence with a type is still rejected;
existing element-to-element nesting is unaffected.

Root cause: the IfcOpenShell-geometry-engine calculator ruleset
(IFC4QtoBaseQuantities.json and IFC4X3QtoBaseQuantities.json) left
IfcWall's GrossFootprintArea/NetFootprintArea mapped to null, so
these two quantities were silently omitted from Qto_WallBaseQuantities
whenever that ruleset was used. The generic gross_get_footprint_area
and net_get_footprint_area formulas already exist and are already
wired up for IfcSlab in the same files, so this was a missing mapping,
not a missing implementation.

This reverts commit b61f809731.
This commit was probably using not updated build, currently latest build is e333c1c and can confirm that it has `logger_or_root` added and `delete_same_facet_edge_pairs` removed.
Footings are authored two ways with different local axis conventions. Beam-like
footings (STRIP_FOOTING, FOOTING_BEAM) are a profile extruded along local Z, so
Length is local Z and the cross section sits on local X (Width, horizontal) and
local Y (Height, vertical). Slab-like footings (PAD_FOOTING, PILE_CAP) have their
footprint on local X/Y and their thickness (Height) on local Z.
The engine rule set is keyed per IfcFooting and cannot branch on predefined type,
so the previous static rule (Height=net_get_z, Length=net_get_max_xy, Width=null)
swapped Length and Height for beam-like footings and never emitted Width.
Add predefined-type-aware get_footing_length/width/height to the IfcOpenShell and
Blender calculators, and point the IfcFooting rule at them in all four IFC4/IFC4X3
ios/Blender rule files.
Confirmed by authoring footings through the real Bonsai generators and measuring
world-axis orientation: a beam-like footing with a 0.3 wide by 0.6 tall cross
section and 6.0 run reports Length 6.0, Width 0.3, Height 0.6, with the 0.3
physically horizontal and 0.6 physically vertical; a 2.0x1.5x0.3 pad reports
Length 2.0, Width 1.5, Height 0.3.

See #6835. Qto_OpeningElementBaseQuantities came out axis-scrambled for
openings authored in a Z-up local frame (X along the voided wall, Y
through it, Z vertical), which is how Bonsai authors every wall opening:
- The IfcOpenShell engine mapped Height to the local Y extent and Depth
to the local Z extent, so a 0.9 x 2.0 door opening with Bonsai's
default 1.2m void depth reported Height 1.2 and Depth 2.0, and Area
(max side area) picked the through-wall side, 2.4 instead of 1.8.
This matches the wrong Height=1.2/Area=1.2 screenshots reported for a
1x1 window opening in #6835.
- The Blender engine mapped opening Width to get_length, which returns
the longest bounding box edge, i.e. the opening height for typical
door openings (the same defect 4adaf0d fixed for IfcDoor Width), and
get_opening_depth used min(x, y), which returns the opening width
whenever the width is smaller than the void depth.
The IfcOpenShell engine now has opening-aware internal calculators
(get_opening_width/height/depth/area) that detect horizontal (slab
style) openings with the same heuristic as the Blender calculator, so
slab opening depths keep reporting the slab thickness. The Blender
ruleset uses get_x for opening Width, and get_opening_depth measures the
through-element Y extent for vertical openings.
Door and window quantities themselves are addressed separately: the
Blender engine door Width was fixed in 4adaf0d, and the remaining
door/window defects (door not quantified on the IfcOpenShell engine,
inflated areas) are fixed by the attribute-based calculators in #8389.

falken10vdl reviewed 16b1b4e7b1 on #8843 and pointed out that tagging
every area for redraw was overkill. The actual problem was that the
Object Material panel and the scene Materials list read from plain
python caches (ObjectMaterialData and MaterialsData) that only get
invalidated when the Materials editing UI list is reloaded, which
never happens while you are not in editing mode. The redraw itself was
never the issue, closing the rename dialog already triggers one.
Removed the tag_redraw loop from RenameMaterial and instead call the
existing bonsai.bim.module.material.data.refresh() function from
core.rename_material, unconditionally, through a new tool.Material.refresh()
method. This is the same invalidate-on-next-load mechanism already used
by every other module's Data classes, just wired up for this operator
too, instead of introducing a new one.
Also updates the core tests to prescribe the new unconditional refresh()
call, and adds tool-layer coverage for tool.Material.refresh().

theoryshaw tested #8843 and asked for the new name to show up right
away instead of needing a manual refresh. The Object Material panel
and the scene Materials list both already re-read live IFC data on
their next draw (tool.Ifc.Operator purges those caches after every
IFC-mutating operator), so the button text was correct on the next
redraw. What was missing was the redraw itself: the material name is
a plain button label, not an RNA property Blender tracks, so nothing
told the Properties editor to repaint after the rename dialog closed.
Tag every area for redraw once the rename completes, the same pattern
used elsewhere in Bonsai for popup-triggered edits that need an
immediate repaint.
Also adds core-layer test coverage for rename_material, which had
none.

Adds a "Rename Material" entry to the context menu that already
extends every button in the properties editor (UI_MT_button_context_menu),
triggered when right-clicking a material name button
(bim.select_by_material) that points to a real IfcMaterial. This
gives a quick entry point to renaming from the Object Material panel
without navigating to the scene Materials list.
This follows the pattern that #6680's thread converged on: theoryshaw
requested a right-click entry (rather than a pencil icon or
double-click) that keeps the existing single-click select-by-material
behaviour intact. falken10vdl is the issue's assignee; this is offered
as a starting point for that discussion, not a replacement for it.

Add an "Is Selected" checkbox to each target-view category header in
BIM_UL_drawinglist that toggles selection for all drawings in the
category. The toggle only affects drawings currently visible in the
list (honoring the show_drawings_on_sheets_only filter), and the header
checkbox reflects the aggregate selection state of its drawings.
Also make category headers more obvious: wrap them in a box() for a
distinct inset background and make the header name clickable to
expand/contract the category (same as the disclosure triangle).

Adds a "Show Only Drawings on Sheets" toggle below the drawing list. When
enabled, the list is filtered to drawings referenced by at least one sheet
(target-view headers with no sheeted drawings are hidden too), and
bim.select_all_drawings only acts on the visible/filtered drawings.
A drawing is considered sheeted when its drawing document Location matches a
document reference Location on any SHEET-scoped IfcDocumentInformation.
Filtering is computed live so it reflects sheet edits without reloading.

* docs: cover the Blender 5.1 / Python 3.13 transition in installation guides
The system requirements still listed Blender 4.3-4.5 with Python 3.11

preferences into a Blender whose Python version changed carries over an
incompatible Bonsai build that silently fails to load. Document the two
Python generations, that Get Extensions picks the matching build
automatically while manual zip installs do not, and the
uninstall-reinstall step that resolves the upgrade case.

* Keep real cause in wrapper ImportError
When the compiled wrapper exists for the current interpreter but fails
to load (for example a glibc version mismatch, as on AWS Lambda in
issue 5927), the bare except rewrote the error into the misleading
"IfcOpenShell not built for '<platform>'" message. Environments such
as AWS Lambda or the Blender add-on dialog only surface the final
exception message, so the actual cause was invisible and undiagnosable.
Keep the "not built for" message only when no matching binary is
present, and otherwise include the original loader error, chaining the
cause in both branches.

Fixes#5927
* Simplify wrapper import failure to a single message
Per review feedback, drop the filesystem scan and the two message
variants. Always raise the classic "IfcOpenShell not built for
'<platform>'" message with the original exception appended in
parentheses, still chained as the cause. Environments that only show
the final exception message (AWS Lambda, the Blender add-on dialog)
now surface the real loader error, such as the glibc version mismatch
in issue 5927, without any extra logic.

The jsGantt-improved library that renders Bonsai's Gantt chart already
ships full support for an "Hour" granularity (column width, header
labels in every bundled language, hour-aware rendering math). Bonsai's
config only exposed Day/Week/Month/Quarter, with a comment claiming
Hour caused browser issues even with vUseSingleCell enabled.
Headless Chrome testing against the same library version shows that
claim no longer holds once vUseSingleCell is active (as Bonsai already
configures it at 10000): Hour-format charts render without errors from
typical schedules up through fairly extreme ones (5000 tasks across a
3 year span rendered in about 2.4s). The failure mode the old comment
described only reproduces with vUseSingleCell disabled, which is not
how Bonsai runs it.
Task start/finish times already flow through to the chart unmodified
as raw ISO datetimes (tool/sequence.py create_new_task_json), so any
schedule authored with real hour-level timestamps, for example an
imported MS Project/P6/Excel schedule or one written directly through
ifcopenshell-python, can now be viewed at hour granularity. Verified
live with a night shift schedule crossing midnight, rendered correctly
with no console errors.
Note: Bonsai's own "Edit Task Time" UI currently always snaps
ScheduleStart/ScheduleFinish to 09:00/17:00 regardless of the hour
entered (ifcopenshell/api/sequence/edit_task_time.py), and work
calendars only encode working days, not working hours. So authoring a
genuine hour-precision schedule through that UI is still not possible;
this change only unlocks viewing hour-level data that already exists
in the model. Fixing the editor and calendar model is a separate,
larger design decision for a maintainer.

* Bonsai: move annotations between drawings when reassigning their group
Assigning an IfcAnnotation to a group that represents another drawing
previously left the annotation in both drawings at once: it stayed in
its old drawing group, its Blender object stayed in the old drawing
collection, and it kept the old camera depth, so the reassignment
appeared to do nothing useful. Issue #2966 documents the seven step
manual workaround users needed instead.
The assign group operator now detects when the target group represents
a drawing (via the new tool.Drawing.get_group_drawing, the inverse of
get_drawing_group), unassigns the annotation from its previous drawing
group, moves its object into the new drawing collection, and places it
on the new drawing camera plane. The target camera is imported on
demand when it has not been loaded yet, matching the pattern used by
the activate drawing operator.
Generated with the assistance of an AI coding tool.
* Bonsai: add one click copy of annotations to another drawing (#2966)
Duplicating an annotation into a different drawing used to require a
seven step manual process: loading groups in scene properties, copying
the object, fixing its group assignment by hand, and repositioning it
onto the target camera plane. A plain Blender duplicate is not enough
because the copy keeps pointing at the same IFC entity, and the Shift D
override, while it does create a genuine new entity through
root.copy_class, leaves the duplicate in the source drawing group,
collection, and camera depth.
The new copy annotation to drawing operator packages the proven recipe
already used by duplicate drawing into one action: duplicate through
tool.Geometry.duplicate_ifc_objects, unassign the copy from the source
drawing group, assign it to the chosen target group, place it on the
target camera plane at the same world XY, and file it into the target
drawing collection. The originals are left untouched and the user's
selection is restored. The target camera is imported on demand when it
has not been loaded yet.
The operator shows a target drawing dropdown and is reachable from the
annotation tool sidebar when an annotation is selected, and from the
drawings panel. Annotations already in the target drawing are skipped
and reported.
The orchestration lives in core.drawing.copy_annotations_to_drawing
with prophecy tests covering the copy, the skip, and the camera import
branches. Verified live in headless Blender 5.1: the copy is a new
IfcAnnotation with its own GlobalId and IfcTextLiteral, both texts are
editable independently, and everything survives save and reload with
each annotation loading in its own drawing.

Fixes#4395.
Root cause: the SVG cut-linework merge step that fuses adjacent
elements' cut polygons together (per the pset-driven JoinCriteria
setting) was hardcoded to only IfcWall and IfcSlab. IfcCovering cut
shapes were skipped unconditionally, so adjacent coverings never
joined, leaving a visible seam/broken corner in section drawings
regardless of JoinCriteria.
Fix: added an EPset_Drawing.JoinClasses property, following the
exact same user-overridable pattern already used by
EPset_Drawing.BringToFront - a comma-separated list of IFC classes
to join, defaulting to "IfcWall,IfcSlab" (unchanged behavior) when
unset. Users can override per-drawing to add IfcCovering (or any
other class) when they want it joined too. Kept this opt-in rather
than hardcoding IfcCovering into the default list, since joining a
thin finish layer the same way as a thick wall/slab could produce
unwanted mitring in some cases - the user decides per drawing.
Verified live against the reporter's own attached file
(ifcovering joining.ifc) and its cached section linework: with
JoinClasses unset, two separate closed paths reproduce the reported
seam exactly. With JoinClasses = "IfcWall,IfcSlab,IfcCovering", the
two coverings merge into a single closed polygon with the internal
seam removed. Confirmed IfcSlab join behavior is unchanged in both
runs.

reimport_element_representations() built a fresh
ifcopenshell.geom.settings() without copying deflection_tolerance /
angular_tolerance from the IfcImportSettings it had just
constructed, and never passed geometry_library to either the
iterator() or create_shape() calls it makes. As a result, exiting
Item/edit mode (which reaches this function via
switch_representation) silently fell back to IfcOpenShell's
hard-coded mesher defaults (0.001 linear deflection, ~50x finer than
the project's default of 0.05) and the default geometry kernel,
instead of the project's configured tolerance and Geometry Library.
This made geometry visibly change quality after a no-op Tab into and
back out of edit mode, since the reload path was unintentionally far
more precise (and used a different kernel) than the initial import.
Both settings, and geometry_library, are now taken from the
IfcImportSettings instance already built at the top of the function,
so a reload matches the original import.

theoryshaw's follow-up on #6944: after the profile/curve reconstruction fix
(previous commit), the arc/circle marker for a freshly Shift+D-duplicated
loop wouldn't appear until leaving and re-entering Edit Mode.
Root cause: ProfileDecorator groups arc/circle vertices purely by
IFCARCINDEX/IFCCIRCLE vertex-group index every draw call (it has no cache
to go stale, it fully recomputes from the live edit-mesh bmesh each frame).
Duplicating a loop copies its vertex-group weights onto the new geometry,
since Blender allocates no new group for a duplicate, so the source loop
and its live duplicate land in the same dict entry. That entry then fails
the "exactly 2 verts per circle / 3 per arc" check and is skipped entirely,
so BOTH the original and the duplicate stop being drawn until the mesh is
reimported and gets fresh, distinct groups.
Verified live in headless Blender: built a bmesh with an IFCCIRCLE loop and
an IFCARCINDEX loop, then ran bmesh.ops.duplicate on each (the same
bmesh-level operation underlying Shift+D) and called ProfileDecorator's
draw method directly. Before this change, duplicating either loop dropped
both the original and the duplicate from the decorator (0 circle/arc
batches drawn instead of 2). After, both draw immediately, with no change
to the non-duplicated case (still 1) or to genuinely distinct loops (5
independent circles still resolve to 5, not merged). 500-circle timing is
unchanged (~14.3ms/draw before and after), so the added connectivity split
is not a hot-path regression.
Added test/bim/module/model/test_profile_decorator_duplicate_loop.py
pinning the new _connected_components helper's behavior for single and
duplicated circle/arc loops.
This contribution was produced with the assistance of an AI coding tool.
auto_detect_profiles had the identical defect fixed in the previous
commit: duplicating a circle/arc loop in Edit Mode reuses the same
IFCCIRCLE/IFCARCINDEX vertex group index for the new geometry, and this
sibling function (used for curve/annotation editing rather than profile
voids) tallied group membership across the whole mesh instead of per
loop, so it also rejected a legitimately duplicated loop as malformed.
Applied the identical fix: scope the group-count sanity check to each
connected edge loop, computed after the loops are built rather than in
the initial whole-mesh vertex pass. Kept the existing forked-loop check
(more than 2 edges per vertex) in the first pass since it is unrelated
to group counting.
Verified live in headless Blender: constructed two 2-vertex IFCCIRCLE
loops sharing one vertex group index (the exact state Blender's Edit
Mode duplicate produces) and called auto_detect_curves directly.
Before this change it returned (False, "CIRCLE"); after, it returns two
valid IfcCircle curves.
Generated with the assistance of an AI coding tool.
Duplicating a circular or filleted-arc void in the profile CAD editor
(Shift+D on the loop's vertices) reused the same IFCCIRCLE/IFCARCINDEX
vertex group index for the new geometry, since Blender's mesh duplicate
copies vertex group weights but does not allocate a new group. On exit
from Edit Mode, auto_detect_profiles tallied group membership across the
whole mesh rather than per loop, so a group meant to hold exactly 2 (circle)
or 3 (arc) vertices ended up with double that, failing its sanity check
and blocking the edit with an "INVALID PROFILE" popup. Fixes#6944.
Scope the sanity check to each connected edge loop instead, matching how
the loops are actually converted into IfcCircle/arc segments below. Also
explicitly reject an arc/circle vertex tagged onto an isolated vertex with
no edges at all, which the old whole-mesh count also caught.
Verified live in headless Blender against the issue's repro file
(IfcFurniture "Slab.004", IfcArbitraryProfileDefWithVoids with three
IfcCircle voids): entering the profile editor, duplicating one void's
2-vertex loop and moving it produced an "INVALID PROFILE" popup before
this change, and now produces a valid profile (the original 3 voids
intact, plus the duplicate as a 4th void or a separate solid profile
depending on whether it still falls inside the outer boundary).
test/tool/test_model.py passes unchanged (32 passed, 1 pre-existing
unrelated failure present on both before and after).

The ci-lint workflow's ty steps fail on every branch because base
v0.8.0 has four diagnostics.
ty check (bonsai):
- root/operator.py: bpy.data.objects.get() can return None, so
UnlinkObject._execute could put None in its objects list and crash
on the first attribute access when an unknown object name is passed.
Handle the miss explicitly, which also satisfies the declared
list[bpy.types.Object] type.
- tool/sequence.py: ty does not narrow Literal types through
membership tests on list literals, so the assert_never() exhaustive
check was flagged. Use tuple literals, which ty narrows, keeping the
exhaustiveness check intact.
ty check (ios):
- draw.py: arrange_polygons was called through conditional argument
splats that let the same call site work against pre-April-2026
wrappers lacking arrange_polygon_settings and the logger parameter.
No runtime bug for current builds, but the dynamic splats cannot be
typed against the fixed 3-parameter signature. Drop the old-build
workaround and call the current signature directly, following the
precedent of 3d8115ebc5 which dropped similar old-build workarounds
in ifcopenshell.file. Verified against a current wrapper build that
the direct call arranges polygons and serializes to SVG, with and
without a logger.
- Optimise.py: igraph is an optional dependency with a guarded import
and a toposort fallback, but it was missing from the ios type-check
venv so ty could not resolve it. Add it to type-check-requirements
next to the toposort fallback that is already listed.

generate_stub.py (this branch's earlier commit) regenerates
ifcopenshell_wrapper.pyi wholesale from the compiled wrapper: it
reliably fixes real drift, but it also discards everything that isn't
mechanically recoverable from the wrapper alone - the license header,
docstrings, and hand-curated named-parameter signatures for
SWIG-overloaded constructors/functions (SWIG itself always emits
generic `*args` for those, so a regenerator can't tell a deliberate
curation from real drift and just overwrites it).
sync_stub.py takes the smaller-blast-radius approach: it only adds
top-level symbols/class members that are genuinely missing, and only
removes ones that are genuinely gone, cross-checking against
validate_stub.py's own full canonicalisation (via the newly-exposed
get_names_tree()) so it never mistakes a property()/staticmethod()-
wrapped member for something absent just because its own narrower
parser skips that form. Anything that exists on both sides under the
same name but with a different signature - exactly where curation
lives - is left untouched and reported for a human to review instead
of guessed at.
Verified against a real local build: applying it to the current
ifcopenshell_wrapper.pyi produces a small, targeted diff (add one
missing method, drop one stale function) with the license header,
docstrings, and all 14 curated constructor/function signatures
preserved byte-for-byte, versus generate_stub.py's ~1000-line
wholesale rewrite for the same underlying fix.

of the schema's attribute count. This left the storage's last N attribute
slots simply nonexistent rather than blank, so any later read of one of
those trailing attributes by index threw an uncaught IfcParse::IfcException
("Index N is out of range for storage of size N") that terminated the
whole process (SIGABRT) instead of being handled as a parse warning.
Fix: when the schema declaration is known, size the storage to the
schema's attribute count. Indices beyond the number of tokens found are
left at their existing default-constructed blank value (the storage
constructor already blank-initializes every slot), so a truncated
instance now degrades to blank values for its missing trailing
attributes, matching the parser's existing "expected N attribute values,
found M" warning intent instead of crashing.
Reproduced with the fuzzing script attached to #5679: single-byte
mutations of a minimal IFC4 file that corrupt the IFCPROJECT instance's
token stream reliably aborted IfcConvert with this exact exception before
the fix, and now parse with a logged syntax error and exit code 0.

set_shape_transparency() called AIS_InteractiveContext.SetTransparency(),
whose argument count is inconsistent across pythonocc-core versions
(reported as a TypeError in #1037). Set transparency directly on the AIS
object instead, the same stable pattern already used elsewhere in this
file (display_shape() calls ais.SetTransparency() directly, never through
the Context), then call Context.UpdateCurrentViewer() to refresh.
app.py's viewer used a "SetSelectionPriority(counter)"/"SelectionPriority()"
pair as an ad hoc unique key to map a displayed AIS object back to its IFC
product. On modern pythonocc-core this crashed with AttributeError because
.GetObject() (needed to unwrap the old handle-based API) no longer exists
on AIS objects (#1098, PR #1113 partially patched one of the two call
sites but left the one in HandleSelection unguarded).
Live pythonocc-core 7.9.3 testing showed the GetObject() guard alone is
not sufficient: SetSelectionPriority/SelectionPriority themselves have
been removed from AIS_InteractiveObject entirely in modern OCCT (only
AIS_Trihedron keeps a same-named but unrelated method for datum parts),
so gating the .GetObject() call with the existing USE_OCCT_HANDLE flag
would still crash the first time a shape is selected. Verified live that
AIS objects retain correct __eq__/__hash__ (matching the underlying OCCT
instance) across separate SWIG wrapper instances, so ais_to_product is
now keyed directly by the AIS object itself, removing the dependency on
the removed OCCT API and the GetObject()/handle distinction altogether.
Verified live against pythonocc-core 7.9.3 (conda-forge) using real
AIS_Shape objects obtained from ifcopenshell.geom.occ_utils.display_shape()
and a real IFC file: reproduced both the original TypeError (#1037) and
AttributeError (#1098), confirmed both fixes resolve them, and confirmed
the ais_to_product dict lookup round trips correctly through a real
Context.Select()/SelectedInteractive() call. Could not exercise the full
Qt-embedded viewer.finished()/HandleSelection() flow end to end because
this pythonocc-core build segfaults natively when creating a second GL
context inside a Qt widget on this macOS host, a pre-existing environment
issue unrelated to this diff (reproduces identically with unpatched code,
before any touched line executes).

create_shape() returns a Python-owned Element (SWIG_POINTER_OWN in the
boost::variant out typemap). Its .geometry property calls Element::geometry(),
which returns a reference into the element's boost::shared_ptr<Representation>
_geometry member. SWIG wraps that reference as a non-owning pointer, so the
returned Triangulation/BRep/Serialization proxy does not keep the element alive.
When a caller keeps only .geometry (e.g. create_shape(s, e).geometry) and drops
the parent element, Python garbage-collects the element, destroying its
shared_ptr and freeing the underlying representation. Subsequent reads of
verts/faces then return freed memory: empty or implausible float/int garbage,
non-deterministically depending on GC and allocator timing. This is silent data
corruption, not a crash, and has bitten users since 2020.
Fix: in the TriangulationElement/SerializedElement/BRepElement pythoncode, wrap
the geometry getter so the returned geometry stores a backreference to its
owning element (result._parent = self). This makes the parent's lifetime at
least as long as the geometry's, automatically and transparently, so no caller
has to remember to hold the element. This is aothms's suggested backreference,
applied generically in the binding rather than left as a workaround.
Reproduced deterministically (washBasin fixture): before, verts len 0 vs 133500
across repeated GC-pressure runs; after, 133500 every run for all three element
types. test_create_shape passes; no regressions.
Note: tree.select_ray()'s ray_intersection_result (2024 follow-up in #1124) is a
separate ownership mechanism (std::vector element reference + std::array member
pointer) and is left as follow-up scope.

recalculate_cut() and recalculate_fill() each ran is_intersecting_camera(),
which builds a bmesh and scans every vertex. When a redraw recalculated both
(camera moved, cache miss, or the object selected) that was two full
intersection tests per object per frame for the same answer.
Compute it once in decorate() and pass it to both, and skip the test
entirely when neither recalculation is needed. Never more tests than before,
identical result since the camera can't move within a frame.

is_camera_moved() runs eval()/numpy over the camera matrix and, as a side
effect, refreshes the stored checksum the first time it returns True. It was
called up to twice per object inside decorate(), so on a frame where the
camera actually moved the first call updated the checksum and every later
call - the fill check on the same object, and both checks on all remaining
objects - then saw an already-current checksum and returned False. Only the
first object's cut got recalculated; its fill and every other element stayed
stale until something else invalidated the cache.
Evaluate it once at the top of __call__ and reuse the flag. This halves the
per-object eval overhead on the common path (viewport navigation with the
camera object stationary) and, when the camera does move, correctly
recalculates the cut and fill for every intersecting element instead of just
the first.

Deleting a type used to strip its occurrences: any that displayed the
type's mapped representation lost their geometry, and inherited material
and presentation styles were dropped too.
The no-SHIFT "Delete Type" path now bakes each occurrence's geometry,
styles, and inherited material onto the occurrence before the type is
removed:
- Refactor UnassignType's unmap logic into a reusable
UnassignType.unassign_and_unmap(), and extend it to re-attach styled
items (copy_deep only follows forward refs, so IfcStyledItem is lost)
and bake down any inherited (non-owned) material.
- Add RemoveType._detach_type_material_set(): unhook the type's
IfcMaterialLayerSet/ProfileSet association cascade-free before deletion,
so remove_product's aggressive unassign_material never fires and the
occurrences' layer/profile-set usages survive intact.

aothms asked for the toposort dependency ordering used by the dedup
walk to try igraph's C-backed topological_sorting() first, since it
should shave off additional time on top of the non-recursive
get_info fix. Falls back to the pure python toposort package with a
warning if igraph is not installed.
Generated with the assistance of an AI coding tool.
The 2020 profiling in issue #1043 found the Optimise recipe's dedup
loop spent almost all of its time in entity_instance.get_info(recursive=True):
because the topological sort already guarantees every referenced entity
is folded before the entity that references it, recomputing each
already-folded subtree's canonical value from scratch for every parent
that points to it is wasted work. Confirmed this is still exactly the
bottleneck in the current codebase, unchanged since 2020 (get_info's
recursive path still walks the whole subtree on every call).
Applied aothms's suggested fix from the issue thread: canonicalize each
entity with a non-recursive get_info, and for referenced entities substitute
the already-computed identity of their folded replacement (looked up in
instance_mapping) instead of re-expanding the subtree. Also limited the
toposort dependency graph to direct references (max_levels=1), since a
topological sort only needs direct edges, not the full transitive closure
traverse() was computing for every entity.
Benchmarked before and after on real IFC test fixtures and a larger
synthetic file with heavily shared geometry (thousands of walls sharing
a handful of profile/point subtrees, mirroring the sharing pattern
described in the issue):
- test/input/geometrygym_great_court_roof.ifc (56989 entities): 9.9s -> 1.7s
- test/input/acad2010_objects.ifc (16296 entities): 3.7s -> 0.4s
- synthetic 120083-entity fixture with heavy geometry sharing: 19.2s -> 3.4s
Verified correctness by comparing the full canonical (recursive get_info)
multiset of the optimized output between the old and new implementation on
all three fixtures: identical results, same fold counts.
Added test_Optimise.py covering the core scenario from the issue: entities
built from separate, value-identical non-rooted subtrees fold to a shared
instance, while entities with distinct values do not.

IfcSurfaceCurveSweptAreaSolid regressed in 0.8 for geometry far from the
origin (for example parapets on a georeferenced building), which went
missing or glitched.
The kernel offsets the directrix toward the origin when it is far away
(mean.norm() > 1e2), storing the offset copy in a local curve variable and
setting applied_temporary_offset so the finished solid is translated back by
+mean. But the wire was still built from scs->curve, the un-offset original,
so the offset never took effect and the result was translated by +mean from
its correct location. Build the wire from curve instead. When no offset is
applied curve aliases scs->curve, so near-origin geometry is unchanged.

Two related bugs in read_from_stream's reference-resolution
loop, both reachable from malformed input:
- has_attribute_value<IfcBaseClass*> only checks the stored
slot's type, not that it's non-null (e.g. an explicit $
value), so the following get_attribute_value() call could
return null and inst->declaration() crashed on it.
- byid_[ref] default-inserts (and returns) a null pointer
when the owning instance id isn't present, which was then
dereferenced unconditionally via ->data().

`values` dictionary was missing and variables were never collected to it, so `FormulaEvaluator(values)` was always resulting in missing variable error.
The fixture declared FILE_SCHEMA(('IFC2X3')) but used
IFCPROPERTYSETDEFINITIONSET(...), a defined type that only exists in
IFC4+ (confirmed absent from the generated Ifc2x3-schema.cpp/
Ifc2x3-definitions.h, present in the IFC4 equivalents). The file's own
FILE_NAME record ('Column_4x3.ifc') suggests it was originally
exported as IFC4X3 and the schema tag was later miscopied to IFC2X3.
Traced with an instrumented parser build: on encountering the
unrecognized keyword, declaration_by_name() correctly throws
"Entity with name 'IFCPROPERTYSETDEFINITIONSET' not found in schema
'IFC2X3'", caught by the existing IfcException handler in
in_memory_file_storage::load(). The parser then falls back to parsing
the trailing (#136,#138) as a plain nested SET rather than the typed
value, so RelatingPropertyDefinition ends up as a bare tuple instead
of an IfcPropertySetDefinitionSet-wrapped value with .is_a(). This is
correct, expected behavior for content that doesn't match its
declared schema - not a parser bug. Fixing the header to IFC4 (which
does declare the type) resolves test_stream, test_file, and test_rocks
in test_streaming_rocksdb_and_simpletyperefs.py.

src/ifcgeom/kernels/opencascade/boolean_utils.cpp, OpenCascadeKernel.cpp,
and boolean_result.cpp logged diagnostics (including the "Processed
fully in 2D" family of messages) through the global Logger::Root()
singleton. IfcConvert's main() constructs its own Logger and wires it
to --log-file via SetOutput(), then threads that instance through
Converter/kernel constructors as logger_ (see AbstractKernel). Since
Logger::Root() is never itself configured with an output stream, every
Notice/Warning/Message call through it was silently dropped instead of
reaching the log file - Logger::Message's log1_/log2_ null checks just
no-op.
This made src/ifcopenshell-python/test/test_wall_opening.py fail: it
asserts on specific log messages that the underlying boolean-op code
was still emitting correctly, just to nowhere. The geometry itself was
never wrong.
Add a Logger*, defaulting to null, to boolean_settings (with a log()
accessor falling back to Logger::Root() for the few remaining
call sites with no injected logger available), thread it through
eliminate_narrow_operands and boolean_subtraction_2d_using_builder,
and have OpenCascadeKernel/boolean_result.cpp populate it from their
inherited logger_ member instead of relying on the global singleton.

The class-pairing validation added in 10ee5aef4f rejects any type
assignment whose class isn't in the buildingSMART implementer
agreement map. That map only covers physical product occurrence/type
pairs (IfcWallType -> IfcWall, etc); IfcTypeProcess and IfcTypeResource
subtypes such as IfcTaskType, IfcProcedureType and the resource types
have no entry, so previously-valid assignments like
IfcTaskType -> IfcTask were rejected with "allowed occurrence
classes: <none>".
These classes still follow the schema's universal Type-suffix naming
convention, so derive the pairing the same way the existing
ApplicableOccurrence fallback does: strip "Type" from the relating
type's class name and accept it only if the schema actually declares
that entity. This can only add pairings implied by the type's own
class name, so it cannot loosen the existing rejection of genuine
mismatches (e.g. IfcWallType -> IfcWindow).

Add svg-use-edge-classification (default off, preserving today's
linework), svg-render-crease-edges, and svg-render-sharp-edges
settings, gating the existing 5-class classification feature so it
can be disabled entirely (falling back to the pre-classification
whole-shape output) or have individual classes suppressed.
Also fixes a bug uncovered while wiring this into Bonsai: ready(),
where geometry_settings() actually gets read into the serializer,
was only ever invoked explicitly by IfcConvert's CLI driver and
isn't exposed to Python. Every Svg* setting -- including the three
from previous rounds -- silently stayed at its hardcoded constructor
default when the serializer was constructed directly through the
Python bindings, as Bonsai does. Fixed by calling ready() from
SvgSerializer's own constructor, safe since it only reads
geometry_settings() with no other side effects, and settings are
always finalized before construction in every call path.

Circular-profile IfcColumn/IfcPile elements produce a genuine
analytic cylindrical BRep face (via BRepPrimAPI_MakePrism), not a
tessellated facet. The edge classification/extraction pipeline is
edge-identity-based end to end, but a smooth surface's silhouette is
synthesized by HLR on the fly and has no corresponding pre-existing
edge to bucket, so it was silently dropped once any edge in the
product had been classified. Add a face-level pass that includes any
non-planar face directly in the outline bucket, giving HLR's
per-face OutLine reconstruction a face identity to correlate
against. Purely additive: diffing the whole test scene's output
before and after shows only the two previously-missing tangent
lines appear, nothing else changes.

Re-enable the view-relative sign flip for folds seen through an
opening (e.g. a box with a face removed), reverted in the previous
commit after it corrupted unrelated geometry. The earlier revert's
diagnosis was slightly off: bucket reassignment can't affect HLR's
own visibility computation, so the corruption was actually an
asymmetric-threshold artifact -- an unconditional flip re-tested
small, correctly-flush deviations against the much smaller valley
threshold instead of the ridge one. Gating the flip so it only
reinterprets folds that already clear their own pre-flip threshold
fixes the box case while leaving every other test object's
classification unchanged (verified against the full test scene).

Fixes three bugs in classify_edge_from_faces() found via real-world
testing against a dedicated stress-test scene (icosphere, Suzanne,
cylinders/cones at various orientations, a dihedral-angle sweep rig):
- The outline (silhouette) test used a bare sign comparison, so a face
at or near exactly edge-on to the camera could land on the wrong
side of zero and fall through to angle-based classification instead
of being drawn as outline. Now uses a tolerance band around zero,
matching an equivalent check already used elsewhere in this file.
- The signed deviation-from-flat formula was inverted (180 - angle
instead of angle), so small, genuinely near-flat facet angles came
out with a large computed deviation and always classified as
sharp/crease, never flush. This is why thresholds appeared to have
no effect. Also replaced the edge/wire-orientation-based convexity
sign (unreliable on real BRep topology, verified wrong against a
known fully-convex icosphere) with a simpler position-based test.
- A specific edge that was previously missing entirely (not just
misclassified) reappears correctly as a side effect of the outline
fix above; no separate change was needed for it.
A fourth issue (folds viewed through an opening, e.g. a box missing a
face, should read as crease rather than sharp) was attempted via a
back-facing sign flip, but reverted: it broke the fixes above broadly,
since "both faces back-facing" isn't a rare look-through-a-hole case
once HLR has already filtered to visible edges only. Documented in a
code comment for whoever picks this up next.

Adds boundary/outline/sharp/crease/flush classification of HLR
projection edges in SvgSerializer, so CSS can style silhouettes,
ridges, and valleys differently instead of drawing every edge
identically (fixes the "ugly faceted sphere" problem from #3668).
Classification happens pre-HLR on the original solid's real face
topology (three prior attempts tried to classify HLR's own output,
which carries no face topology at all and can't be correlated back
by edge identity). Each class's visible portion is then extracted via
HLRBRep_HLRToShape::VCompound(S)/OutLineVCompound(S), the same
per-shape filtering mechanism already used for per-product
segmentation, applied per class instead. Classes are tagged directly
on individual <path> elements so Bonsai's merge_linework_and_add_metadata
group-level class rewrite in operator.py never touches them.
New settings: svg-ridge-angle-min-degrees, svg-valley-angle-min-degrees,
svg-emit-flush-edges (ConversionSettings.h), wired through Bonsai's
CreateDrawing operator and exposed via its redo panel.

The Reassign Class operator refused to reassign an element to a different
IFC product family unless it was an IfcElement <-> IfcElementType swap, so a
piece of geometry mistakenly hosted on IfcSite could not be turned into
IfcFurniture even though root.reassign_class handles it fine.
Loosen the guard: only block the case that actually matters - a spatial
element (IfcSpatialElement / IfcSpatialStructureElement for IFC2X3) with no
geometry, which would be a real containment-hierarchy container rather than
a stray modelled object. Everything else reassigns freely.

* Bonsai: place auto-generated opening boundaries at their real position #8237
auto_generate_boundaries (single-space mode) built each opening/filling boundary
from the opening's LOCAL geometry (get_vertices) but first did
mat.translation = (0, 0, 0) on its placement matrix. Because the vertices are
local, that placement translation is exactly what carries the opening to its
real location, so zeroing it collapsed every window/door boundary onto the
origin. This is why the auto path misplaced window boundaries while the
single-element path (create_element_boundary) placed them correctly, as
@MDHering observed with the two modes. Keep the full placement matrix.
Verified on the reporter's file: the opening's real placement is (0.1, 1.5, 1.0);
a vertex went from (0.6, 0, 0) under the old code to (0.7, 1.5, 1.0) with the fix,
i.e. moved by exactly the (0.1, 1.5, 1.0) that was being discarded.

The failing step (the_object_name_exists in test_feature.py) dumps the
full bpy.data.objects listing on failure, so the correct current ids are
recoverable directly from the CI log (run 29208793599, tested commit
36e21e882f, an ancestor of HEAD with only a .gitignore commit between).
Renumber to match:
IfcExtrudedAreaSolid/77->73, IfcPolygonalFaceSet/76->72,
IfcVertexPoint/69->65, IfcEdge/72->68, IfcFace/74->70.
Verified against the CI failure dump (a local build produces different
ids, so this is validated by CI's own object listing rather than a local
run). boolean.feature also hardcodes IfcHalfSpaceSolid/90 and panel text
[91] downstream of the failing assertion, which CI never reached and so
never dumped; left as-is to avoid guessing - they will print a fresh dump
next run for a follow-up if still stale.

Two host-environment bugs in the build-env scripts that break on
macOS/Apple Silicon hosts, independent of target architecture:
- Dockerfile: groupadd fails outright when USER_GID collides with an
existing system group in the rockylinux9 base image (e.g. macOS
default user GID 20 "staff" collides with RHEL's GID 20 "games").
Guard with getent so useradd attaches to the existing group instead.
- ifcos_env: `sed -si` is GNU-only syntax and errors under BSD/macOS
sed. Do the UNIQUE_ID substitution via a portable temp-file + mv.
Per sboddy's review on the original PR: dropped the linux/amd64
platform-pin additions from this change. The stack already targets
Rocky9/x64 build outputs by design, and Docker Desktop on macOS has
no native container runtime regardless (it's a Linux VM either way),
so forcing the image to run under emulation doesn't produce anything
that's actually loadable into a native macOS Blender/Bonsai install.
That's a separate, harder problem worth solving via a native build
path instead (mirroring build_osx.yml), not by fighting emulation
here. These two fixes stand on their own merits on any host.
This change was made with the assistance of an AI tool.
The ccache named volume had no explicit name, so Docker Compose
namespaced it under the per-checkout project name (derived from
UNIQUE_ID), giving each checkout its own cache even though
docker/README.md already documented them as shared. Give the volume
a fixed name so all checkouts attach the same one.
Measured cache size after a full build (IfcParse+IfcGeom+IfcConvert+
wrapper, one Python version) is ~300MB, only ~5% of the previous 5G
cap. Shrink CCACHE_MAXSIZE to 2G, which comfortably covers the shared
baseline plus per-branch deltas from several diverging checkouts.
Generated with the assistance of an AI coding tool.
Three host-portability fixes to the docker/ toolchain from #8564 so it
runs on macOS as well as Linux. All three are no-ops on native amd64
Linux.
1. Dockerfile: only groupadd when the target GID is free. macOS's default
primary group `staff` is GID 20, which already exists as `games` in
rockylinux:9, so `groupadd -g 20` aborted the image build. Guard with
`getent group "${USER_GID}" || groupadd ...`; useradd -g accepts the
existing GID.
2. ifcos_env unique(): replace GNU-only `sed -si` (BSD/macOS sed errors
"illegal option -- s") with a portable `sed > tmp && mv` rewrite of the
UNIQUE_ID line. Verified against macOS BSD sed.
3. create() + compose.yaml: build with an explicit `--platform linux/amd64`
so the locally built image's platform matches the `platform:
linux/amd64` pin in compose.yaml. Without it, on arm64 the local image
is tagged linux/arm64, compose treats the platform-mismatched image as
absent and tries to pull `ifcopenshell-build-env:updated` from Docker
Hub (which does not exist -> access denied). Also add `pull_policy:
never` as a safety net so a future mismatch surfaces as a clear "image
not found" rather than a registry auth error.
Note: on Apple Silicon the amd64 build runs under emulation and a cold
full build is slow; ccache makes incremental rebuilds tolerable. A native
Linux/Intel host or CI remains the better choice for routine use, but these
fixes turn "hard broken" into "works with a caveat" on macOS.

Reported: Blender segfaults when clicking Cancel on the "newer
autosave found" recovery popup shown by LoadProject at startup.
Root cause: LoadProject.execute()/invoke() triggered the recovery
popup via bpy.ops.bim.load_autosaved_recovery_popup("INVOKE_DEFAULT",
...) and returned that call's result ({'RUNNING_MODAL'}) as their own
return value, without LoadProject itself ever calling
modal_handler_add(). Blender's window manager takes a RUNNING_MODAL
return as a promise the operator registered its own modal handler;
since it hadn't, the WM's operator bookkeeping was left corrupted -
silently, since this is heap/state corruption rather than an
immediate crash. It only surfaced later, when the real modal operator
(the popup) closed and the WM reconciled its modal stack, which lines
up with the crash occurring specifically on dialog close regardless
of which button was pressed. check_autosave_recovery() now returns a
plain bool and fires the popup fire-and-forget; LoadProject reports
its own honest {"FINISHED"}.
Also hardened, as defense in depth: LoadAutosavedRecoveryPopup's
execute()/cancel() call back into bim.load_project(...), which (with
should_start_fresh_session) calls wm.read_homefile() and tears down
the window manager/screens. Doing that synchronously from inside this
popup's own execute()/cancel() - itself invoked from deep inside
Blender's modal handling for the popup's button click - risks the
same class of use-after-free as the timer bug fixed in the previous
commit. The reload is now deferred by one timer tick so it runs after
the popup's modal handling has fully unwound, and the deferred
callback closes over plain values rather than `self`, since the
operator instance may not survive past cancel()/execute() returning.
This defer-only change was tried and tested first, on the (incorrect)
assumption it was the root cause: it produced a byte-for-byte
identical crash backtrace on retest, which is what pointed at the
RUNNING_MODAL bug above as the actual cause - the defer change alone
was insufficient because the corruption happens when the popup is
first shown, not when it's closed.
Generated with the assistance of an AI coding tool.
The periodic autosave timer called reset_timer() at the end of its
own callback, which unregistered the timer that was still executing
(itself). Blender frees the timer's internal registry entry on that
manual unregister, then frees it again when the callback returns
None - a double free that corrupts the heap and can crash Blender
later, once the corrupted memory is reused.
Reschedule by returning the next interval from the callback instead,
which is the safe, documented way to repeat a bpy.app.timers
callback. External reset_timer() calls (from SaveProject,
LoadProject, AutosavePrompt) are unaffected since they run from a
separate call stack (UI events), not from inside the timer.
Found while investigating a segfault reported when cancelling the
autosave recovery popup; not itself the cause of that crash (see the
following commit), but the same reentrant-unregister pattern and a
real, independent latent bug in the periodic reminder path.

Dockerfile (renamed from Dockerfile_init, Dockerfile_update removed):
- Run as a non-root `builder` user matching the host UID/GID (passed as
--build-arg by create() from id -u/id -g), so build output under the
bind mount stays owned by the host user instead of root.
- Fix CCACHE_MAXSIZE: `ccache -M 5G` wrote its limit to a config file
under /ccache at image-build time, but /ccache is a volume mount
point, so that file gets shadowed by the (empty) volume the moment
the container actually runs - the cap never took effect. Set
CCACHE_MAXSIZE=5G as an image ENV instead.
- Dedupe ccache/libffi-devel, add --setopt=install_weak_deps=False
--setopt=tsflags=nodocs, add `git lfs install --system`, combine the
dnf update+install into one layer.
- Drop Dockerfile_update: it built FROM its own previous output, so
every `update` call made the image strictly larger forever (Docker
layers are append-only, `dnf clean` in a later layer can't shrink an
earlier one). `update` now just calls create(), which already runs
`dnf update -y` FROM a clean rockylinux:9 every time.
compose.yaml: pin platform: linux/amd64 so this doesn't silently run
under emulation on an ARM host.
ifcos_env:
- Split the previously-conflated stop/down into six distinct,
Compose-native lifecycle commands: up (create-or-start), down
(remove), stop, start, restart (stop+start, same container),
recreate (down+up, fresh container). Previously `stop` was aliased
to `down`, which silently removed the container instead of pausing
it.
- Implement try(): copies the built wrapper into a real Blender/Bonsai
install for manual testing, reading the target from a new
BLENDER_USER_RESOURCE .env variable and auto-detecting the built
Python version (disambiguating via PY_TGT for multi-version builds).
Deliberately kept human-only - it mutates a live Blender install, so
it shouldn't run unattended as part of an automated/AI workflow,
which should instead copy the wrapper into the repo's own
src/ifcopenshell-python/ifcopenshell/ (documented in SKILL.md).
- Fix unique(): the "has .env already got a UNIQUE_ID line" check
referenced an unset $FILE instead of $ENV_FILE, so it always
evaluated true and appended a fresh "UNIQUE_ID=dummy" line to .env
on every single `up`.
- Minor: differentiate remove()'s log message from down()'s (no longer
identical now that they're distinct operations), tidy help text
alignment and a stray double-space typo in clean().
SKILL.md: rewritten as current-state documentation (no more "fixed in
this copy" changelog framing) covering the above, plus a migration
note for anyone hitting root-owned leftovers from an older image.
Verified by actually building the image and driving every new
lifecycle command (stop/start/restart keep the same container ID;
down+up and recreate produce a new one) and try() (including the
quoted-tilde BLENDER_USER_RESOURCE edge case) against the real container.

First functional version, but it needs some improvements and fixes
identified as I've used it personally on one thing, and when an AI

I had the AI make a SKILL.md file. If the AI indicates it needs to

The project-unit to Blender-unit mapping in format_distance only knew
FOOT/INCH/METRE/DECIMETRE/CENTIMETRE/MILLIMETRE, so creating a project
with Kilometers or Miles in the New Project Wizard crashed with
KeyError: 'KILOMETRE' (or 'MILE') as soon as the spatial tree formatted
an elevation. Add the missing Blender-supported units (kilometre, mile,
micrometre) and fall through gracefully for anything else (for example
HECTOMETRE) so unknown units use the adaptive formatting branch instead
of raising.

Expose the Euler rotation of an element's placement in degrees through
get_element_value, alongside the existing x/y/z and easting/northing/
elevation keys. This makes element rotation exportable through ifccsv,
e.g. for placing oriented symbols in GIS.
Adopts the approach agreed in the review of the stale PR #6272 by
@TZwielehner: reuse util.shape_builder.np_matrix_to_euler and do the
degree conversion inside get_element_value.

Project loading set scene length_unit to f"{Prefix}METERS", but Blender's
enum only defines KILOMETERS, CENTIMETERS, MILLIMETERS and MICROMETERS.
A model with a DECIMETRE (or HECTO/DECA/etc.) length unit therefore raised
on the enum assignment and the file failed to open. Guard with the set of
supported values and fall back to ADAPTIVE display for the rest.

IfcDiff defaulted to relationships=["geometry"], so a plain diff only ever
compared geometry. Attribute-only edits on an element that kept its GlobalId
(a modified or removed PredefinedType, a renamed element, etc.) were silently
missed. The CLI made this worse: --relationships did not list "attributes" or
"geometry" as valid values, so there was no documented way to enable it.
The default is now ["attributes", "geometry"], so a plain `ifcdiff old new`
reports attribute changes alongside geometry changes. The CLI help and the
IfcDiff docstring now document all valid relationship values.
Added a regression test covering a PredefinedType change detected with the
default configuration.

FormatTransformer.round() called Decimal() directly on the input value,
which raises decimal.InvalidOperation when the value is a non-numeric
string (a text property, or a value carrying a unit suffix like "12.5 m").
In a spreadsheet export this crashed the entire operation as soon as one
element carried such a value.
Now round() catches InvalidOperation and returns the value unchanged, the
same graceful-fallback convention used by add(). Numeric rounding is
unaffected.

In the cobie24 Coordinate sheet, Floor rows use get_local_placement, whose values
are in the project length unit, but Space rows come from ifcopenshell.geom
create_shape, whose vertices are in SI metres, and the space branch never scaled
them back. So on a non metre model (for example millimetres) the Coordinate sheet
mixed units a thousandfold apart and disagreed with the Facility sheet's declared
LinearUnits.
Scale the space bounding box by the project unit scale so the whole Coordinate
sheet is consistent. A metre model is unchanged since the scale is 1.

The filter_elements selector grammar had no way to comment out part of a
query, so users had to delete and retype text to temporarily toggle a
facet. Add a /* ... */ block comment terminal that is ignored by the
lexer, and tolerate a trailing "+" so that commenting out the final
operand (e.g. "IfcWall + /* IfcSlab */") parses cleanly. Comments may
span multiple lines; a /* sequence inside a quoted string is not treated
as a comment. Only the filter grammar is affected, not get_element or
format which use "/" for regex and division.
Adds a regression test and documents the syntax.

Property sets contained in an IfcPropertySetDefinitionSet were exported as
an empty element in XML. The XmlSerializer already had a block to expand
such a set into its member property sets, but it was gated behind
#ifdef SCHEMAS_HAS_IfcPropertySetDefinitionSet while the schema generator
emits SCHEMA_HAS_IfcPropertySetDefinitionSet (singular). The plural spelling
is defined nowhere, so the block was dead code and a RelatingPropertyDefinition
holding a set produced nothing.
Correct the macro name so the set is expanded and its property sets are
serialized. The parse layer already reads these nested sets (they are
reachable from util.element), so this only completes the XML path.

escape_xml escaped the five XML metacharacters but passed control
characters (0x00 to 0x1F other than tab, newline and carriage return)
through unchanged. Those bytes are illegal in XML 1.0 and cannot be
represented even as numeric character references, so any IFC string
containing them produced non-well-formed XML and SVG output.
Strip those illegal control characters before escaping. Bytes belonging to
a valid UTF-8 multibyte sequence are always >= 0x80, so filtering on the low
control range leaves real text intact. This is the shared helper used by the
SVG serializer text and attribute sites (audited: all route through it) and
by the XML/Collada paths, so both reports are resolved at one place.

IfcTriangulatedFaceSet and IfcPolygonalFaceSet used CoordIndex values to
index Coordinates.CoordList directly, ignoring the optional PnIndex
attribute. When PnIndex is present it remaps point references, so a
CoordIndex value i must resolve as CoordList[PnIndex[i-1]-1] (both 1-based).
Without the indirection any model carrying a PnIndex was built from the wrong
points.
Add a resolve() helper in both mappings that applies the PnIndex indirection
when present and is a plain bounds-checked lookup otherwise, with bounds
checks at both index levels. When PnIndex is absent the behavior is unchanged.

Boost.System has been header-only since Boost 1.69 and its compiled stub
library was removed in newer Boost, so listing system in the requested
find_package components makes configuration fail on Boost 1.70 and up (for
example Boost 1.90 errors with "Could not find boost_system"). Boost.System
is still pulled in transitively by thread / iostreams where it is needed, so
drop it from the explicit component list.

Address maintainer request on #8368: instead of a deflection floor on top
of a fixed CircleSegments count, use one mode or the other. When
CircleSegments == 0 (the new default) the CGAL kernel derives the conic
segment count from MesherLinearDeflection, matching the deflection based
meshing OpenCascade already does and fixing #8051. When CircleSegments is
non zero it is used directly as a fixed, radius independent count.
CircleSegments is only read by the CGAL kernel; OpenCascade meshes by
deflection and never reads it, so the new default has no effect there.
Update the setting description and the ifcconvert / geometry-settings docs.

The CGAL kernels (cgal and cgal-simple) allocate arc segments as a
fraction of the full circle via CircleSegments, ignoring the radius.
A large-radius arc that spans a small angle therefore collapsed to a
single chord, turning curved curtain-wall mullions straight while the
OpenCascade kernel (which meshes by deflection) kept them curved.
evaluate_conic now also enforces a deflection-based floor on the number
of segments, keeping the chord deviation within mesher-linear-deflection,
matching OpenCascade. Small circles are unchanged (CircleSegments floor
still dominates); only large-radius curves get denser.

IfcConvert returned a success exit code even when geometry conversion logged
errors and silently dropped elements (for example a failed TopoDS::Shell build
under layerset slicing produced valid looking output with most objects
missing), so CI and scripts could not detect a partial conversion.
Add an opt-in --fail-on-error flag that makes IfcConvert exit non-zero when any
error was logged during processing, reusing the existing MaxSeverity based
failure check already used for --validate. The default exit behaviour is
unchanged, so pipelines that tolerate individual element failures are
unaffected.

A face whose inner boundary crosses the outer boundary (or another inner
boundary) is invalid per the schema. Open Cascade silently heals or drops
such a face, so the intended hole is lost or the face is corrupted with no
diagnostic at all (the 2018 report saw a dropped face; on the current line
the face survives as wrong geometry, still silently).
After the wires are collected, if a face has inner boundaries, measure the
BRepExtrema distance between each inner wire and every earlier wire. Two
non intersecting loops have strictly positive distance, so a distance at
or below the modelling precision means the boundaries touch or cross; emit
a warning (GEO 402) naming the offending face. This is diagnostic only, no
geometry change.
The message is emitted via the kernel logger() rather than Logger::Root():
IfcConvert configures a local Logger and worker logs merge into it, while
Logger::Root() is a separate unconfigured singleton whose messages are
discarded (a latent issue affecting some existing GEO messages too).
Verified on OCC 7.9.2 with synthesized IFC4 faces: an inner triangle
crossing the outer edge, and one straddling the bottom edge, each emit one
GEO 402; a valid 4x4 hole emits none and triangulates identically (area
84.0), in both sequential and multithreaded runs. Pure inner self
intersection and full containment are distinct classes and intentionally
left untouched.

In IFC2X3 IfcAsymmetricIShapeProfileDef is a subtype of
IfcIShapeProfileDef, so the IfcIShapeProfileDef mapping dispatched it by
inheritance. From IFC4 onwards it is a standalone subtype of
IfcParameterizedProfileDef, so nothing mapped it and the extruded solid
came out empty (GEO326, 0 verts).
Add a dedicated map_impl that builds the twelve-point asymmetric section
(independent bottom/top flange widths, thicknesses, fillet/edge radii and
flange slopes), plus a guarded BIND. Both are wrapped in
SCHEMA_IfcAsymmetricIShapeProfileDef_HAS_BottomFlangeWidth, which is only
defined where the type is standalone, so IFC2X3 keeps its existing
subtype route unchanged.
Verified on OCC 7.9.2: an IFC4 asymmetric extrusion goes from 0 verts to
a correct 72-vert solid (bottom flange wider than top); IFC2X3 output is
unchanged.

Feature #5753 - Autosave for ifc files
Merging because it could be a life saver. It is hidden behind an option and is off by default.
- Provides the option have an autosave file created periodically (duration in prefs).
- Can be set to save immediately or a dialog prompt to save, but can be dismissed.
- Removes the autosave when Blender quits cleanly.
- If the autosave file exists at startup, it will prompt which file to load.
_Every_ AI had a hand in this, but I have reviewed, understood and tested it. AI Credits go to:
Cursor, Grok, Copilot, and Claude.
- autosave.py: black formatting (blank line) and ruff's
collections.abc.Callable import fix.
- project/__init__.py, tool/__init__.py: ruff import-sort fixes. The
autosave import in tool/__init__.py is deliberately kept last (must
come after tool.drawing, per its existing comment) via `# isort: skip`
rather than letting ruff move it, which would reintroduce that bug.

The recovery popup used invoke_popup, which is dismissed the instant
the mouse leaves its bounds - closing the prompt without loading
either file, and with no visible feedback that anything happened.
Switches to invoke_props_dialog, which blocks the rest of the UI and
is only dismissed by an explicit action. Since Blender always renders
both a fixed "Cancel" button and one labelled by confirm_text on that
dialog type, the prompt is reframed as a direct Yes/Cancel question
("Do you want to load the autosaved version instead?") instead of
adding separate Load Original/Load Autosave buttons on top of those.
Folds the load logic directly into the popup's execute()/cancel(), so
the now-redundant LoadAutosavedRecovery operator is removed.

Previously the autosaved copy was only ever overwritten, never removed,
so a deliberate quit (whether the user saved or chose "don't save")
still nagged with a recovery prompt on next startup.
Registers an atexit cleanup that removes the active IFC's autosave
file(s) on a graceful interpreter shutdown. atexit never runs on an
actual crash, so a genuine crash still leaves the recovery file in
place as before.
The cleanup reads a cached plain-string path kept up to date by
reset_timer(), rather than looking it up live via bpy.context - by
the time atexit fires, Blender's C++ side is torn down far enough
that even a read-only bpy.context.scene access aborts the process
(std::bad_optional_access) instead of raising a catchable exception.

Implemented as described in #5753, with two options:
- A nag dialog with save or cancel options.
- An autosaved file.
Settings are in preference to activate the feature (default: off), the period before prompting/saving,
and choosing between the two methods.
Prevent the autosave file being added to the recent files list when the user opens the original, but selects to open the autosaved version.

- add_stationing_referent.py: black reformat (new drift from v0.8.0).
- update_fallback_position.py: v0.8.0's changes to this file made the
ifcopenshell.util.unit import (added in an earlier commit here) unused;
removed per ruff.
poe ty's sequence only reaches ty-ios once ty-bonsai passes, so these
never surfaced until now:
- util/alignment.py: drop the stale `include_referent=False` kwarg from
add_zero_length_segment() - that parameter was removed from the function's
signature in 45ea5eb07 but this caller in a different file was missed,
leaving a latent TypeError if this code path is ever exercised.
- ifcopenshell_wrapper.pyi: add the optional trailing `logger` parameter to
parse_ifcxml/open/construct_iterator*, matching the real SWIG signatures
in src/ifcwrap/*.i (all declare `Logger& logger = Logger::Root()`) that
the hand-maintained stub never picked up.
- ifcopenshell/__init__.py: remove a stale `ty: ignore[unknown-argument]`
comment that ty confirms is no longer suppressing anything.
- assign_cost_item_quantity.py: OPERATORS mixes 2-arg binary operators with
the 1-arg `operator.neg` (for ast.USub), but FormulaEvaluator has no
visit_UnaryOp so USub can never reach this lookup via visit_BinOp.
Suppressed at the call site rather than touching the dict, since this
looks like scaffolding for unary-minus support rather than dead code.
- Explicit submodule imports (ifcopenshell.geom / api.alignment / util.unit
/ api.aggregate / api.context / api.spatial) added where accessed but
only reachable by accident of import order.
- tool.py: drop the `-> int` annotation on the Parametric interface's
get_geom_generation stub; its `pass` body implicitly returns None, which
ty can't reconcile with the runtime @interface/@abstractmethod rewriting
it never sees statically. Matches the file's other stubs (-> None).
- railing.py: qualify the "BIMRailingProperties" string annotations as
"prop.BIMRailingProperties" on the two functions using it, since the bare
name was never imported into this module's namespace.
- product.py: suppress ty's missing-argument errors on
copy_z_rotation_to_selected's Surveyor.get_z_rotation/set_z_rotation
calls with targeted ty: ignore comments. The function is unused and its
two dependencies were never implemented on the concrete Surveyor tool;
left as-is rather than deleted or implemented.
- gizmos.py: TYPE_CHECKING-guard `import bmesh` for the string-literal
annotation in build_schematic_mesh; suppress the still-unresolved

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.

Introduce tool.Array.select_only_parent and wire it into both

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

AggregateModeDecorator, PolylineDecorator, ProductDecorator,
WallAxisDecorator, SlabDirectionDecorator, FaceAreaDecorator,

uninstall removed each handler from Blender but never cleared
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

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
tool.Parametric.commit_object_draft before the mesh import, gated
on tool.Parametric.is_object_editing so the guard is a no-op when

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

PRE_VIEW handlers updated clip_planes but skipped the

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

absorb float-precision drift that scales with the box's world

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.
Used by the clip-box feature to compute cross-section caps per IFC
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 +
fillet-lock commit (wall.py's ``either_is_fillet`` chain rewraps the

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.

ChangeExtrusionDepth, ChangeExtrusionXAngle, and ChangeLayerLength
mutate IFC extrusion / axis but never re-prime BIMWallProperties from
the post-mutation state. Gizmo icons that position from props.height
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
default) it offsets a new copy of the selected edges as
before; when disabled it moves the existing edges to the
offset location instead. The toggle is exposed in the CAD
tool's Offset panel and the operator redo panel.

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.
Build note: wall.py's DisconnectElements._perform imports
bonsai.core.connection.disconnect_rel — that core module is being
added in a parallel-session commit. Until that lands the addon
import will fail.

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.
Generated with the assistance of an AI coding tool.
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
lane.

Port gizmos-8088's railing gizmo block to v0.8.0:
- _RailingEditMixin (PathPreservingEditMixin specialisation) +
EnableEditingRailing / CancelEditingRailing / FinishEditingRailing
edit triad
- CycleRailingType (2-value type cycler) + ToggleRailingUseManualSupports
one-shot + EditRailingTerminalType
- FlipRailingPathOrder + EnableEditingRailingPath /
CancelEditingRailingPath / FinishEditingRailingPath path-edit
operators (mutually exclusive with the schematic frame)
- GizmoRailingSchematic (BaseSchematicGizmoGroup specialisation) —
axonometric schematic frame with per-attribute dimension gizmos
for FRAMELESS_PANEL + WALL_MOUNTED_HANDRAIL railing types;
hover-on-attr highlights the schematic edges tagged with the
matching feature
Tests: test_railing_lifecycle.py (280 LOC) +
test_railing_schematic.py (272 LOC).
Drops the per-feature GizmoPreferences{Door,Window,Stair,Wall,Roof,
Railing} PropertyGroups that the source commit added to bim/ui.py
— that finer-grained per-attribute toggle model was deliberately
collapsed to flat per-feature bools in the PR5b prefs sweep, and
GizmoRailingSchematic gates on the flat ``prefs.gizmos.railing``
bool via ``gizmo_pref_name`` so no functionality is lost.
