BuildingInformationModel.save

BuildingInformationModel.save(path, schema=None, tessellation_tolerance=0.001)

Save the IFC file to disk, optionally converting to another schema.

Since the model is a bi-directional front-end, the IFC file is always in sync with the model tree. When schema is None or matches the current schema, this simply writes the file.

Cross-schema export — converting the model to a different IFC schema ("IFC2X3", "IFC4", or "IFC4X3") on save, tessellating advanced B-Reps at tessellation_tolerance where the target schema cannot represent them — is not yet implemented.

Parameters:

pathstr

Output file path.

schemastr, optional

Target IFC schema. If None (default) or equal to the current schema, the model is written as-is. Any other value currently raises NotImplementedError.

tessellation_tolerancefloat, optional

Chord deviation (in metres) intended for tessellating advanced B-Reps during a downgrade export. Reserved for the not-yet- implemented cross-schema export path. Default 0.001.

Raises:

NotImplementedError

If schema names a different schema than the current one.
