Bundled bug fixes + the forward-compat AST guard that prevents the
underlying class of bug from coming back.
* bim/module/model/wall.py: FinishEditingWall._execute early-returns
CANCELLED when props.is_editing is False. Without this guard, a
failed enable (e.g. on a wall without IfcMaterialLayerSetUsage)
leaves is_editing False but a press on finish still walked the
sub-ops below, which dereferenced layer-set-dependent state and
crashed.
* tool/model.py: Model.offset_wall now guards against
ifcopenshell.util.element.get_material returning None before
calling .is_a("IfcMaterialLayerSetUsage"). Fixes the pre-existing
test/bim/module/model/test_wall_header_refresh.py crash that has
been the only failing test in the wall lane since this branch
started.
* bim/handler.py: _apply_save_file_invariants drains
wall_offset_gizmos.clear_caches() on load_post. The module-scope
GenerationKeyedCache instance survives the .blend reload; without
the drain the cache may serve entries whose bpy_struct references
point into the freed bpy.data of the previous file.
* test/bim/test_handler_forward_compat.py: AST-walk test that
enumerates every bim/module/model/*.py source declaring both a
module-scope GenerationKeyedCache assignment AND a top-level
clear_caches function, and asserts each module appears as a
<module>.clear_caches() call in _apply_save_file_invariants. Pins
the contract: any future module-scope geom cache that exposes
clear_caches must wire into the load_post drain.
* test/bim/feature/model.feature + test/bim/test_feature.py: wall
edit-lifecycle scenarios switch from "add cube + assign as
IfcWallType" to "load the demo construction library + add an
occurrence of the WAL100 wall type", so the parametric edit runs
against a real LAYER2 wall with IfcMaterialLayerSetUsage rather
than a vanilla-mesh promotion that lacks one. The demo-library
step also picks the schema-matching library file (IFC2X3 /
IFC4 / IFC4X3) so the appended types remain valid across schemas.
Door saved-height assertion updates from 2.5 → 2500 to reflect
that BBIM_Door pset stores project units (METRIC_MM in the
empty-project fixture).

IfcOpenShell
IfcOpenShell is an open source (LGPL) software library for working with Industry Foundation Classes (IFC). Complete parsing support is provided for IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and IFC4x3 Add2. Extensive geometric support is implemented for the IFC releases IFC2x3 TC1 and IFC4 Add2 TC1. Extending with support for arbitrary IFC schemas is possible at compile-time when using C++ and at run-time when using Python.
In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to other formats), Bonsai (an add-on to Blender providing a graphical IFC authoring platform), and many other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
