IfcOpenShell Element Traversal and Querying
Quick Reference
Decision Tree: Finding Elements
Need to find IFC elements?
├── Know the IFC class? (IfcWall, IfcDoor, etc.)
│ └── model.by_type("IfcWall")
│ ├── Need subtypes included? → include_subtypes=True (DEFAULT)
│ └── Need exact type only? → include_subtypes=False
│
├── Know the STEP ID? (#123 in .ifc file)
│ └── model.by_id(123)
│ └── WARNING: STEP IDs are NOT persistent across re-exports
│
├── Know the GlobalId? (22-char IFC GUID)
│ └── model.by_guid("2O2Fr$t4X7Zf8NOew3FLOH")
