Three concerns bundled into one cohesive refactor of gizmos.py (splitting them surgically requires intermediate commits with duplicate same-named classes that Python can't parse): 1. Framework primitives — StaticTrisGizmoMixin + TexturedQuadGizmoMixin replace the older TrisGizmoMixin. New module-level helpers: _get_static_tris_shader / _get_static_tris_batch / clear_static_ tris_cache for cached GPU batch reuse, _draw_outline_and_body for the shared outline-then-body render path, draw_tris_with_outline as the public wrapper. billboarded_at(world_pos, billboard_rot, scale) is the canonical billboard-matrix helper; should_flip_extend_ arrow encapsulates the view-aware mirror decision for extend gizmos; get_warning_color_from_prefs reads the user's warning color. 2. Config classes — BaseValueGizmoConfig (shared visibility + dimension- text contract), CountGizmoConfig (array N indicator), DimensionGizmoConfig (length / height / depth labels), IconActionConfig (icon-only gizmos that invoke an operator on click). DimensionRenderer draws the actual numeric label using BLF. 3. Icon classes — each rewritten on StaticTrisGizmoMixin so they share the cached GPU batch + outline-then-body render path: GizmoLockOpen / GizmoLockClosed (replacing the single-state GizmoLock), GizmoArc, GizmoFillet, GizmoWallCornerIcon, GizmoWallTeeIcon, GizmoPen / GizmoValidate / GizmoCancel (the parametric-edit triad), GizmoPlus / GizmoMinus / GizmoTrash, GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator (array context indicators with a small digit-rendering helper for the "xN" count label), GizmoMerge / GizmoSplit / GizmoUnjoin (wall-join icons), and GizmoMenu (textured-quad icon-action menu trigger). The legacy TrisGizmoMixin, GizmoLock, and DimensionDrawConfig are removed; downstream callers in subsequent PR4 commits swap to the new mixin and config classes when their feature operators land. CycleTypeMixin / PickTypeMixin / TypeAccessorBase live in bim.parametric_lifecycle (previous commit). The three mixins are re-exported from gizmos.py here so feature-module access via ``gizmo.<MixinName>`` keeps working until PR5 cleanup drops the re-exports. bim/module/drawing/__init__.py is updated in the same commit to register the 11 new gizmo classes (GizmoLockOpen / GizmoLockClosed / GizmoFillet / GizmoWallCornerIcon / GizmoWallTeeIcon / GizmoTrash / GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator / GizmoUnjoin / GizmoMenu) — without that, the new classes exist in gizmos.py but aren't usable as bpy gizmo types.

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.
