bimdelta-core
Element-level diff engine for IFC building models, built on IfcOpenShell.
from bimdelta_core import load_settings, run_diff
result = run_diff("rev-a.ifc", "rev-a.ifc", "rev-b.ifc", "rev-b.ifc", load_settings())
print(result.summary.added, result.summary.removed, result.summary.modified)
print(result.model_dump_json(indent=2))
Elements are matched by GlobalId, then by the authoring tool's element id in IfcElement.Tag,
then by class, name, storey and placement. Matched pairs are compared on properties and
quantities, placement, type, storey and a geometry signature (bounding box and volume).
A noise filter keeps export artefacts out of the result; see docs/noise-filter.md.
