driveStreamingLoads could deadlock: a chunk waiting on asynchronous
pool growth parks in a frame-counted backoff cooldown, but once the
render loop quiesced after the settle burst the frame index froze, so
the cooldown never expired and streaming stalled part-loaded until the
user moved the camera. Keep the loop alive while growth may still land
(growth_pending() || can_grow()), exposed via a new BufferPool accessor.
loadSidecarMetadataWeb put the model in the scene before reading the
element-metadata block header, leaving a window where the locator was
still zero. A getObjects() landing in that window could not distinguish
"locator not read yet" from "sidecar has no element block" and latched
the model as permanently empty. Read the 16-byte header first, then
apply; carry the locator through applyCachedModel so it is set before
any web element-metadata fetch can run.

When replacing a style on an item whose previous IfcStyledItem wraps its styles
in the deprecated IfcPresentationStyleAssignment, and the assignment is not
being reused (use_style_assignment is False, e.g. an IFC4 file authored by
AVEVA E3D), the else branch called remove_same_type_styles(style_assignment)
with style_assignment still None, raising
AttributeError: 'NoneType' object has no attribute 'Styles'. Operate on style_,
the assignment found in the current iteration, instead of the accumulator.
Verified red-green with a minimal IFC4 file using IfcPresentationStyleAssignment.

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
values selected). Strip the negation for the per-item comparison and negate
the aggregate instead, so != means "no item equals" and stays the complement
of =. The same applies to !*=.

Right-clicking a model in the models panel now offers "View Selected Model",
which frames the camera on just that model's geometry — View All, scoped to
one model. With several models selected the action reads "View Selected
Models" and frames their union, matching how the panel's existing Move to
Group already treats a multi-selection.
The AABB fold behind viewAll moves into InstanceCompose, which exists so this
kind of logic is unit-testable without a Qt window or a wgpu device (populating
ViewportCore's model map needs a real GPU, so the fold was previously
untestable in place). It splits in two:
- sceneWorldAabb — every VISIBLE model, what viewAll frames.
- modelsWorldAabb — only the named models, hidden or not. A model the caller
named explicitly is framed even if hidden; second-guessing
that is worse than honouring it. Models with no loaded
geometry contribute nothing, and if none of them do the
camera is left alone rather than flying to the origin.
Both are covered by six new cases in test_instance_compose (131 total).

Give host pages a real API over the web viewer, not just "embed it and listen
for picks": read/set the camera, read/set multi-selection, enumerate every
object with its IFC identity, drive per-object visibility, and override
object colours.
The wasm boundary keeps to object_ids (u32 arrays marshalled through the heap,
with an "ask twice" convention on the getters); web/ifcviewer.js layers IFC
GlobalId resolution on top, from the element table getObjects() fetches. Every
id-taking call accepts an objectId, a GlobalId, or an element object.
Colour override needed no new mechanism: color_override_rgba8 was already
plumbed through the sidecar, the instance SSBO, the WGSL shader and the
opaque/transparent cull classifier, but nothing ever wrote a non-zero value
into it. setObjectsColor is the missing writer, which is why an alpha below 255
correctly reclassifies the instance into the transparent pass.
Two bugs surfaced while wiring this up:
- wgpu_initialized_ was only ever set by the Qt desktop host, so on web every
upload guarded on it was a silent no-op — including the pre-existing
recomposeAndUploadModel that federation transforms depend on. The core now
latches it in its own web init.
- The demo pages were copied into the build dir by a POST_BUILD command on the
wasm target, so they only refreshed when the wasm itself relinked; editing a
page left a stale copy that the dev server (and the Playwright suite) kept
serving. Each page now has its own copy rule with a real dependency, and
sample.ifcview is a LINK_DEPENDS so regenerating it forces a relink.
applyCachedModel also now keeps the element metadata it already parses on the
path-based load (it was being dropped), so the embedded sample has GUIDs and
the demo works with no file to pick.
The sample model was three coincident cubes, which made per-object hide and
colour look like no-ops — whatever you hid was still drawn by the box behind
it. make_sample.py regenerates it as a slab, a wall and a beam in distinct
places, so the fixture is reproducible rather than an opaque blob.
Demoed by web/scripting.html (linked from the index; viewer is on
window.viewer) and covered by tests/scripting.spec.mjs — 6 cases against a real
GPU, asserting visibility and colour at the pixels, not just at the API.

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.
This change was made with the assistance of an AI tool.
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.

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.
Fixes#7029.
