End-to-end fillet flow on top of the helpers + recreate_wall hook (landed in the previous commit). Users select two LAYER2 walls, click the fillet entry icon, drag the live radius widget, and validate to replace the corner with a curved LAYER2 corner wall (banana body). Operators (5): * EnableWallFilletPreview: 2-wall selection → validates LAYER2 + straight axis + zero-slope + intersect-or-joined state → seeds the preview props with a default radius computed from the shorter available leg. * FinishWallFilletPreview: dispatches CreateWallFillet with the tuned radius; clears preview state on FINISHED, preserves it on failure so the user can re-tune without re-selecting. * CancelWallFilletPreview: clears preview state, no IFC mutation. * EnableWallFilletPreviewFromCorner: pen-icon re-edit on an existing fillet corner — pre-fills the preview from the corner's BBIM_Wall pset + walks the inverse graph to recover wall A and wall B. * CreateWallFillet: deletes any prior corner + A↔B path connection, shortens A and B to the tangent points, instantiates a corner wall from A's type, unassigns the swept-layer material/type (the explicit banana body MUST own its geometry), assigns the dominant material, rebuilds the body, sets a straight 2-point chord axis, stores BBIM_Wall.IsFilletCorner+FilletRadius, reconnects A and B to the corner with NOTDEFINED on the corner's side. Gizmo groups (2 new + entry icon on existing): * GizmoWallFilletPreview: visible while a preview is active. Bundles a radius_dim widget at the arc apex, a trim_dim widget along wall A expressing the same DOF via the leg setback distance (trim = |radius| * tan(sweep/2)), and validate / cancel icons anchored above the apex in screen-up. * GizmoWallFilletReedit: pen-icon entry on an existing fillet corner wall (single-selection, BBIM_Wall.IsFilletCorner set, both neighbour connections present). Mutually exclusive with an active preview. * GizmoWallJoinIntersection now stacks a fillet entry icon (VIEW3D_GT_fillet → bim.enable_wall_fillet_preview) above the existing join/unjoin icon in the joined and intersect state branches. Property + decorator infrastructure: * prop.py: BIMWallFilletPreviewProperties (Scene-level draft) + BIMPreviewProperties umbrella with only the wall_fillet pointer. The umbrella is the seam preview_base.py (landed in PR3) already reads via getattr(scene, "BIMPreviewProperties", None). * decorator.py: _stroke_lines_alpha helper + WallFilletPreviewDecorator. Polls is_active; renders leg projections + arc + arc-center construction lines from tool.Wall.compute_wall_fillet_geometry. * __init__.py: registers operators + gizmo groups + property groups + wires Scene.BIMPreviewProperties. * handler.py: WallFilletPreviewDecorator.install/uninstall in _install_decorators — always installed, self-polls on is_active. Drive-by: extract gizmo.get_screen_up(billboard_rot) helper — the local +Y of a billboard rotation is the camera's screen-up world direction. Replaces 4 inline `billboard_rot @ Vector((0.0, 1.0, 0.0))` sites added across the fillet feature's gizmo groups. Generated with the assistance of an AI coding tool.
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.
