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.

"""Side-effect-free slab helpers — IFC reads for LAYER3 extrusions.

|
Exposes ``read_geometry``: a single live read of the parametric attributes
|
|
(extrusion depth and slope) that drive icon placement and dimension display
|
|
on a LAYER3 slab. Lives in ``tool/`` so bim-layer callers can stay
|
|
declarative — they get a dict, not an IFC walk."""
