The toggle_openings icon lived outside the IconSlot layout — each host (wall, roof) declared an ad-hoc setup_pen_row_toggle_openings_icon + update_pen_row_toggle_openings_icon pair, and GizmoArrayEdition queried a hardcoded _FEATURE_IDLE_MAX_X dict to position past it. On an arrayed wall the dict was shadowed: find_for_element returns "array" before "wall" in EDIT_TYPES order, the wall reservation was never consulted, and the first per-layer ARRAY icon (local X=0.37) landed 13cm from the wall's toggle_openings (X=0.50) — visually on top of each other. Promote idle-row icons into the slot system instead of patching the dict: * IconSlot gains an Optional visible_when predicate for state-driven visibility (toggle_openings only when the host carries openings). * BaseParametricGizmoGroup gains idle_slots: ClassVar[tuple[IconSlot]] + _idle_slot_x_positions() + _idle_row_right_edge() helpers; the setup + idle-branch positioning loops mirror the existing feature_slots path. * Wall and roof declare toggle_openings as an idle_slot and drop their ad-hoc setup/update calls. * GizmoArrayEdition's _resolve_feature_idle_max_x walks BaseParametricGizmoGroup.REGISTRY and takes the max _idle_row_right_edge() across peers whose poll passes — no more hardcoded dict, no more find_for_element-order shadowing. * setup_pen_row_toggle_openings_icon + update_pen_row_toggle_openings_icon helpers deleted from drawing/gizmos.py. * 3 forward-compat AST guards pin the new contract. Also bundles an unrelated array-test fix: TestUsingArrays in test/tool/test_model.py was asserting against bpy.context.selected_objects which is a fragile signal after remove_array / apply_array. A new _array_objects() helper filters bpy.data.objects via the BIM_Array pset's IfcActuator type instead. Layout on an arrayed wall after the fix: pen X = 0.00 toggle X = 0.50 (idle_slot 0) array[0] X = 0.87 (one ICON_ARRAY_GAP past idle row) array[1] X = 1.27 All separated by the standard inter-icon spacing. 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.
