tool.Model gains: * get_pipe_segment_props / get_duct_segment_props — typed prop accessors for the MEP-segment edit lifecycle. * resolve_active_props_for_edit — picks the right BIM*Properties to drive a parametric edit triad based on the active object's IFC class. * mirror_parent_void_fillings_to_children — when an array parent has hosted fillings (door/window in a wall), replicate the same fill rels onto each array child. Uses tool.Array.get_parametric_propagation_ targets so the propagation stays within the array family (the old get_all_element_occurrences over-propagated to standalone occurrences of the same type, which silently mutated unrelated arrays). * unshare_opening_representation — fork a shared IfcShapeRepresentation so editing one opening doesn't mutate its array sibling. * duplicate_ifc_objects gains a post-condition select-restore on the array parent so callers don't get a deselected parent for N>=2 arrays. sync_object_ifc_position is kept as a thin delegate to tool.Geometry.commit_placement_if_moved (the new home, added in C8) so the 6 v0.8.0 callers in mep / product / system don't AttributeError; PR4 migrates each caller and removes the delegate. tool.Pset gains: * upsert_pset — get-or-add-or-edit in one call. * write_bbim_data — JSON-encode + write BBIM_* metadata in one call. tool.Slab is new — slab-specific reads (active extrusion, axis direction) used by the slab gizmos, pure-IFC, no PropertyGroup mutation. 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.
