Install

pip install git+https://github.com/aec-platform/ifc-spf.git

Not on PyPI yet — this installs from source.

Run

python -c "from ifcspf import Model; print(len(Model.open('b.ifc').of_type('IfcDoor')))"

The layer the open tools stand on. Four parts, each usable alone: a tokeniser and parser for ISO 10303-21; a schema layer that addresses attributes by name and expands subtypes, held as data rather than code; unit resolution to SI; and property sets, quantity sets and the spatial chain. This reads what an IFC file states about itself — which is exactly what takeoffs, code checks, audits and exports actually need, and all they need.

What makes it different

ISO 10303-21 parser in pure Python — installs anywhere, including inside a locked-down CI runner
Schema as data: attributes by name, subtype expansion, no code generation step
Units resolved to SI, property and quantity sets flattened along the spatial chain
