The recent per-gizmo-prefs cleanup left ``update_swing_gizmos`` with a stale ``prefs`` reference that raised NameError mid-refresh, so the flip arc's ``matrix_basis`` was never reassigned and the gizmo drifted to the world origin. SINGLE_SWING_RIGHT also lacked an X-mirror on the primary arc, so the swing extended past the door's right edge instead of sweeping back over the panel. Five related fixes / additions: * Drop the leftover ``prefs.decorations_colour[:3]`` per-frame colour override (the setup-time ``decorator_color_special`` is the durable contract — there's no reason to overwrite it every refresh). * Add X-mirror to RIGHT-hinged single-panel transforms so the arc sweeps back over the door rather than past the right edge. * Treat DOUBLE_DOOR_SINGLE_SWING as a two-panel layout: 4 arcs total (left + right panels, each with its own Y-mirrored flip) scaled to ``overall_width / 2``. * Hide all swing arcs for SLIDING_TO_LEFT / SLIDING_TO_RIGHT / DOUBLE_DOOR_SLIDING — sliding doors don't swing. A slide-direction indicator is deferred to a separate change. * Pin ``select_bias = -1000.0`` on every arc gizmo so the big quarter-arc hit shapes don't steal clicks from the smaller dimension and edit gizmos drawn on top. Architectural cleanup driven by the same diff: the imperative 4-create + 50-line update block is replaced by a declarative ``swing_arc_props`` list of ``SwingArcConfig`` entries (mirrors the existing ``dimension_gizmo_props`` pattern). Setup iterates the list and creates one (main, flip) pair per entry under ``gizmo_swing_arc_<name>`` / ``gizmo_swing_arc_<name>_flip``; update iterates the same list and positions each pair via the lambdas. Adding a hypothetical multi-panel variant becomes a config entry rather than two more attribute names plus a transform branch. ``ToggleDoorSwing`` gets a ``description`` classmethod that returns user-facing wording per ``flip_geometry`` branch so the tooltip on hover stops reading like operator internals. ``test/bim/module/model/test_door_gizmos.py`` (new) pins the per-door-type contract: 11 cases covering LEFT / RIGHT hinge positions, DOUBLE_SWING parity with SINGLE_SWING, DOUBLE_DOOR 4-arc layout, the sliding-types hide invariant, ``is_editing=False`` hide invariant, flip-arc matrix re-assignment, and world-matrix pre-multiplication. Verified: ``pytest test/bim/module/model/test_door_gizmos.py`` 11/11 green; combined wall + stair + door gizmo lanes 37/37 green; ruff + black clean on the three touched files.

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.
