The parametric edit toolbar row used to assign each feature icon its own ICON_<NAME>_X constant, with a separate FEATURE_ICON_MAX_X override each subclass had to bump whenever a new icon was added. Forgetting the bump silently collided icons — wall's rotate icon and the array button both landed at X=1.24 in edit mode. The new IconSlot dataclass + feature_slots tuple replace the constants-and-override pattern with order-driven positioning: the layout manager assigns each slot an X from its tuple index plus a uniform ICON_ARRAY_GAP. Adding an icon is now a one-line append; the "forget to bump" failure mode is structurally impossible. Slot capabilities cover every existing icon-row shape: * Single icon (wall rotate, array delete). * N-variant slots — N gizmos at the same X with one visible per frame via a subclass picker (stair tread-lock open/closed, wall baseline exterior/center/interior). Pair becomes the N=2 case; triplet the N=3 case. Variant idnames can be authored either as a tuple of explicit names or as a string prefix that auto-suffixes _<variant>. * Visibility prefs gate slot rendering without reflowing the row — hidden slots still consume their X position. * Extra per-slot gap before for visual separation (array's delete trails the routine controls by an extra 0.2 m). * Operator props forwarded to target_set_operator so adjusters (+/-, increment) and generic toggles (property_name=...) work. When the cycle slot is unused, feature slots collapse into the cycle position so the row stays tight — that's how wall's baseline triplet sits at X=0.87 without a gap before it. Three subclasses migrate to the new system: * wall.py — rotate icon + baseline triplet variants. Drops ICON_ROTATE_X, _BASELINE_GIZMO_ATTRS, the manual triplet creation loop, and the matching positioning block in _update_icon_row_extras (it now just picks variant visibility). * stair.py — tread_lock pair (open/closed) + plus + minus. _update_editing_icon_positions reads slot X via _slot_x_positions instead of three hardcoded constants. Also fixes the standalone total_length_lock gizmo, which was broken since PR4 split VIEW3D_GT_lock into open/closed pair (caller wasn't updated). * array.py — count_minus + count_plus + method + delete (with extra_gap_before=0.20 to separate the destructive action). Drops the manual edit-row positioning loop entirely; the base loop handles it. GizmoArrayChild now inherits BillboardingGizmoGroupMixin and uses the shared setup_icon_gizmo helper, dropping its duplicated _make_icon wrapper. Two helpers added on BillboardingGizmoGroupMixin to fold the duplicated prefs/color preamble that appeared at the top of six wall gizmo setups plus the array-child setup: * get_decoration_colors() — (decorations_colour, decorator_color_selected), the active-state pair. * get_unselected_decoration_colors() — (decorator_color_unselected, decorator_color_selected) for gizmos surfaced on already-selected geometry that should not pull focus. Verified: headless smoke green at 1267 BIM_OT_ classes, test_parametric_registry.py 8/8 pass, wall lane 29/29 pass, model lane unchanged at 135 pass + 7 pre-existing v0.8.0 failures (no regressions). ruff + black clean.

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.
