Add openings — GizmoWallAddOpening only fired when a wall was active + co-selected with a non-host; slabs and roofs got no in-viewport handle. GizmoHostAddOpening covers all three host types via is_supported_host, dispatching walls to the axis-projection anchor and slabs/roofs to a world-Z anchor lifted just above the host's top face (predictable height regardless of the void's vertical position). Show openings on hosts with their own parametric-edit toolbar — GizmoRoofEdition gains an idle-row toggle_openings_gizmo parallel to the wall's, parked at the cancel-slot X next to the pen. Visible only when the host carries HasOpenings and the edit triad is idle. Roof overrides get_element_height to return the mesh's world-AABB top in object-local Z, so the WHOLE pen-row anchors visibly above sloped or stepped roof bodies. The wall's idle-row toggle now also hides when HasOpenings is empty. Show openings on hosts WITHOUT a parametric-edit toolbar — GizmoHostToggleOpenings scoped strictly to the fallback case: a single host selected, HasOpenings non-empty, NOT a path-connectable wall, NOT a parametric roof. Covers slabs today plus any foreign-authored IfcRoof without BBIM_Roof. Anchored at object origin XY + world-AABB top Z. When slab parametric-edit eventually lands, the slab predicate joins the exclusion list and this gizmo's poll narrows automatically. Operator move — ToggleWallOpenings was already host-agnostic; renamed to ToggleHostOpenings in opening.py (bl_idname bim.toggle_host_openings). Three callers (the wall idle-row binding, GizmoWallFilletToggleOpenings, and workspace.py's hotkey_A_O for Alt+O) now route through the renamed operator. The Alt+O binding is surfaced in the operator's bl_description so it appears in F3 search and hover tooltips. DRY refactors — * GizmoWallAddOpening deleted (subsumed by GizmoHostAddOpening) * tool.Blender.get_object_world_bounding_box added as the world-AABB sibling of the existing local helper; 3 inline call sites in tool/misc.py (set_object_origin_to_bottom, scale_object_to_height) and gizmos.py adopt it (2 other sites in drawing/operator.py and project/operator.py inherently need raw transformed corners for per-corner plane / NDC tests — not AABB candidates) * BaseParametricGizmoGroup gains setup_pen_row_toggle_openings_icon + update_pen_row_toggle_openings_icon; wall + roof + any future host gizmo wire up the idle-row toggle with two one-line calls * _resolve_active_host shared poll prologue between the two host gizmos (gate + selection count + active-in-selected + entity lookup + supported-host check) * HasOpenings non-empty checks at 3 sites route through tool.Geometry.has_openings * hotkey_A_O body collapsed to bpy.ops.bim.toggle_host_openings() The forward-compat AST guard pinning "must accept fillet-corner walls" retargets from GizmoWallAddOpening.poll to is_supported_host.

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.
