Bundle of bugs surfaced when exercising the new gizmo framework end-to-end in a live Blender session after the bim/module/drawing/gizmos.py refactor + TypeAccessor/CycleType/PickType mixins landed. Register / annotation resolution * parametric_lifecycle.py: hoist `entity_instance` import out of TYPE_CHECKING so typing.get_type_hints resolves the Callable[[entity_instance], bool] annotation at operator registration (CycleDoorType, CycleWindowType, CycleStairType failed with NameError). Clarify the INTERFACE return contract on the picker entry-point so readers see why the gizmo step stays off the undo stack. Framework callable contracts * model/wall.py, door.py, window.py, stair.py: migrate `props_getter` and `element_checker` from bl_idname strings to bound classmethods on tool.Model / tool.Parametric. BaseParametricGizmoGroup.get_props expects a callable; the string form raised TypeError on first gizmo poll. * model/door.py, model/stair.py: drop the dead `prop_path=` operator kwarg from create_arc_gizmo / create_icon_gizmo call sites. The framework helper blindly setattrs every kwarg onto the operator's OperatorProperties, but ToggleDoorSwing / ToggleStairProperty don't declare prop_path — the setattr raised mid-setup_element_specific_gizmos, so self.gizmo_door_type / self.lock_gizmo never got assigned and every subsequent draw_prepare tornadoed AttributeError. Nothing reads op.prop_path anywhere; the kwarg was dead data. Dispatcher operators * model/array.py: add EnableEditingParametric (the framework pen-icon dispatcher that routes to a per-feature edit operator by bl_idname string) and AddArrayFromFeatureEdit (binds the framework's array icon to bim.add_array on the current parametric draft). * model/__init__.py: register both new operators. Per-frame robustness * drawing/gizmos.py: guard BaseParametricGizmoGroup.draw_prepare with is_setup_complete() — matches the existing guard in refresh() and in BaseSchematicGizmoGroup.draw_prepare(). Defense-in-depth: when any subclass's setup raises mid-way, draw_prepare now no-ops cleanly instead of per-frame AttributeError-tornadoing on whatever attribute the failed setup phase was meant to populate. * model/decorator.py: guard ProfileDecorator.__call__ against context.active_object is None. The decorator is a per-frame viewport draw handler; deselecting or deleting the active object while it's installed crashed on obj.mode access. Treat None the same as "no longer in edit mode" — uninstall + fire the exit callback if present. * geometry/data.py: ViewportData.load() populates `data` before flipping `is_loaded`, so a raise from cls.mode() no longer leaves the class flag-set but data-empty for subsequent reads. 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.
