Pset names containing spaces (e.g. "SOLIDWORKS Custom Properties") were
not quoted when building selector keys in SelectSimilarData, causing
get_element_value to fail when the operator ran. Now wraps pset names
and property names in double quotes if they contain spaces, consistent
with the selector syntax used elsewhere.

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.

Bsdd.get_dictionaries() unconditionally did cls.client = bsdd.Client(),
replacing whatever client was already set - including the
bSDDClientStub the BDD suite injects at module load
(test_feature.py: tool.Bsdd.client = bSDDClientStub()) to avoid live
network calls. Because "Load bSDD Dictionaries" is the first step of
every bsdd.feature scenario, the stub was discarded before its fixture
data ("LCA", "BonsaiTestDict") could ever be returned.
The re-init is unnecessary: bsdd.Client.__init__ only sets baseurl and
blank tokens, and the next line already updates baseurl defensively via
hasattr. Drop the clobbering assignment; reuse whichever client is
already set.
Verified in headless Blender: bsdd scenarios (load dictionaries, search
all/single dictionary) go from 3 failed ("Could not see LCA/
BonsaiTestDict") to 3 passed.

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.
Fixes the root cause flagged in IfcOpenShell#8706 (Moult), obviating the
need for MergeDuplicateContexts' own manual aggregate-dedup pass for that
scenario.

Fixes issue #3910's documentation gap. IsDefinedBy() returns
IfcRelDefinesByProperties relationship objects, not the property set
itself, and RelatingPropertyDefinition() must be used to reach the
IfcPropertySet or IfcElementQuantity. Properties can also come from an
element's type via IsTypedBy() -> RelatingType() -> HasPropertySets(),
a path that is easy to miss because it works differently. Adds a
worked, beginner-commented, compilable example covering both paths.

The ifcopenshell take-off engine left every Qto_EarthworksFillBaseQuantities
value null, so Bonsai added the qset with no numbers on IFC4X3 models. Map the
geometrically derivable quantities using the slab axis convention: Length on
local X, Width on local Y, Depth on local Z, and the net solid volume as the
compacted (Fill) or undisturbed (Cut) volume. LooseVolume and Weight stay
unmapped because they need soil bulking and density factors absent from
geometry. Bring IfcEarthworksCut to parity with the Blender engine and wire
IfcReinforcedSoil on both engines.

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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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
(Blender derives these from sibling IfcCovering decomposition geometry,
which this per-element calculator architecture can't reach).
Verified on IFC4 (4x3 space extruded 2.5m): before -> {} / elements_quantified 0;
after -> GrossFloorArea 12, GrossPerimeter 14, Height 2.5, GrossVolume 30,
etc. - all exact matches to the extrusion. IFC4X3 formulas are identical
and the formula->function resolution is schema-agnostic.
Scope: fixes the IfcSpace case (the issue title). The 12 other all-null
classes noted in the issue (IfcDoor, IfcSite, IfcRailing, ...) are left as
follow-up.

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.

* 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.

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.

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.
After this, poe ty-bonsai and poe ty-ios both pass cleanly.

The script called Polyline.get_mode() on every modelspace entity, but
that method only exists on POLYLINE entities, so any typical DXF
containing lines, circles or text crashed with AttributeError before
converting anything. Test for POLYLINE polyface meshes with
dxftype()/is_poly_face_mesh instead and skip other entities with a
message, only create the spatial containment relation when products
exist, and take the input/output paths from the command line (matching
obj2ifc.py) instead of a hardcoded input.dxf/test.ifc.

When grabbing an array child, the selection now expands to include
the array parent and all sibling children before the move operator
runs. Mirrors existing behavior for aggregates and nests.

Ran the new sync_stub.py against a real local build: adds
context.delete_same_facet_edge_pairs (present on the compiled wrapper,
missing from the stub) and drops the module-level logger_or_root
(present in the stub, no longer exists on the wrapper at all).
Nothing else changes - no license header rewrite, no docstring loss,
none of the 14 hand-curated named-parameter constructor/function
signatures touched, unlike the wholesale regeneration this replaces.

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.

When a STEP instance has fewer attribute tokens than its schema declares
(commonly from corrupted/malformed syntax), parse_context::construct()
sized the in-memory attribute storage to the smaller token count instead
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.
Fixes#5679
