Use when developing Bonsai (formerly BlenderBIM) extensions, scripting BIM workflows in Blender, or understanding the Bonsai addon architecture. Prevents the common mistake of using ifcopenshell.open() to access the model instead of tool.Ifc.get() which gives the live Bonsai IFC file.

Keywords: Bonsai, BlenderBIM, tool.Ifc.get(), bpy.ops.bim, native IFC, addon architecture, IFC-backed properties, BIM authoring, how does Bonsai work, Bonsai internals, Bonsai API.

Use when performing clash detection, interference checking, or spatial coordination in BIM models using Bonsai and IfcClash.

Covers clash set definition, element filtering, smart grouping of results, and BCF integration for issue tracking. Keywords: clash detection, IfcClash, interference, collision, spatial coordination, clash set, element filter, BCF integration, clash report, find collisions, elements overlap, pipes through walls.

Use when creating custom Blender UI panels, menus, or UIList elements. Prevents the common mistake of using wrong bl_space_type/bl_region_type combinations (panel won't show).
