Ports roof parametric edit gizmo group from gizmos-8088 and folds in
three roof-mesh bug fixes surfaced during live testing.
Port:
* ``CycleRoofGenerationMethod`` operator (bim.cycle_roof_generation_method)
cycles props.generation_method between "HEIGHT" and "ANGLE". Shift+click
cycles in reverse via the ``CycleTypeMixin`` contract.
* ``GizmoRoofEdition`` gizmo group: 3 dimension gizmos for height
(visible in HEIGHT mode) / slope angle with tan/atan2 rise round-trip
+ degree formatter (ANGLE mode) / roof_thickness. All three handles
anchor at the object's local origin and separate visually via their
declared axes (height/slope +Z, thickness -Z) — height + slope are
mutually exclusive via ``visibility_condition`` so they never paint
at the same time. Anchoring at the origin sidesteps the first-click
default-identity-matrix symptom that footprint-derived anchoring
would have hit on a stale ``RoofData`` cache.
* Lifecycle factory swap: explicit ``EnableEditingRoof / CancelEditingRoof
/ FinishEditingRoof`` classes replaced by ``tool.Parametric.build_edit_lifecycle("roof", _RoofEditMixin, ...)``.
Same bl_idnames out, no external caller changes.
* Registration: ``CycleRoofGenerationMethod`` + ``GizmoRoofEdition``
added to ``bim/module/model/__init__.py`` classes tuple.
* Tests: ``test_roof_gizmos.py`` covering slope round-trip, visibility
gates, cycle operator metadata, and origin-anchored positioning.
Bug fixes:
* ``generate_hipped_roof_bmesh`` flipped the bottom slab face's normal
at low slope angles. The kernel's outward-inference becomes
ambiguous on near-flat geometry once ``remove_doubles`` and
internal-face deletion run, and the early ``recalc_face_normals``
pass at line 389 ran BEFORE the topology was final. A second pass
on the final closed mesh fixes the eave plane (now reliably points
down regardless of slope).
* ``bpypolyskel.polygonize`` can emit a face whose vertex list
contains the same index twice on certain footprint/slope
combinations (a straight-skeleton ridge collapse). ``bm.faces.new``
rejects those with ``found the same (BMVert) used multiple times``,
aborting the whole rebuild. Filter the degenerate faces out so the
rest of the roof renders.
* ``_RoofEditMixin._restore_viewport_after_cancel`` now rebuilds the
bmesh from the just-restored draft via ``update_roof_modifier_bmesh``.
The hook was abstract on ``PathPreservingEditMixin`` and raised
``NotImplementedError`` on cancel-after-edit, leaving the user
stranded.
Also folds in a parallel ``tool/loader.py`` swap from
``tool.Blender.Modifier.is_railing`` to ``tool.Parametric.is_railing``
(consistent with the rest of the loader using ``tool.Parametric.*``).
Verified: headless smoke green, test_parametric_registry.py 8/8,
test_roof_gizmos.py 15/15. ruff + black clean on the touched files.

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.
