To create an IFC model programmatically, use the ifcopenshell.api.run() method to generate projects, define spatial hierarchies, instantiate BIM elements, and assign property sets. This enforces automatic GlobalId generation and OwnerHistory management for data integrity.

Setting up a spatial hierarchy in IFC involves sequentially creating Site, Building, and Storey entities. Using the ifcopenshell API ensures these spatial structures are properly linked and compliant with BIM standards for both IFC2X3 and IFC4 schemas.

Yes, ifcopenshell supports creating models for both IFC2X3 and IFC4 schemas. It addresses specific schema requirements, including OwnerHistory differences and varying entity support, ensuring your BIM elements comply with the target IFC version.

Assign property sets to BIM elements by executing dedicated API commands during the model generation workflow. This allows you to attach detailed metadata to elements like walls, slabs, and doors directly from your Python code.

Yes, you can generate a complete multi-storey building model from Python code. The API provides step-by-step workflows to instantiate walls, slabs, doors, and their relationships, building the entire spatial structure programmatically.

OwnerHistory is required when creating IFC elements to maintain data integrity and track model modifications. The ifcopenshell API manages OwnerHistory automatically during entity creation, fulfilling specific IFC2X3 and IFC4 schema requirements.
