IFC Model Creation Workflows

Quick Reference

Decision Tree: Starting a New IFC Model

Creating a new IFC model?
├── Production model with proper header/metadata?
│   └── YES → model = ifcopenshell.api.run("project.create_file", version="IFC4")
│
└── Bare-minimum test file?
    └── model = ifcopenshell.file(schema="IFC4")
        └── WARNING: No header, no project, no units. Add these manually.
