Exchange with IFC 2x3 workflows still common in public-sector and legacy projects.
Round-trip design and reference models with IFC4-capable applications.
Exchange infrastructure entities such as alignments, roads and rail beyond building models.
Move viewpoints and issues between this product and coordination tools.
Check models against an Information Delivery Specification.
Link model objects to buildingSMART Data Dictionary classifications.
Hand over asset and maintenance data to owners and operators.
Deliver models against a defined model view definition.
What that means in practice
- Both IFC4 and IFC 2x3 are covered, so it can exchange with modern tools and with projects still specifying 2x3.
Limitations & evidence
- Exporter settings, product version and the receiving application can still restrict a specific exchange, even where a format is supported.
- Supporting an IFC file format is not the same as IFC certification. No certification is claimed here unless a source is linked.
- Tracked as partial: IFC4.3, BCF and IDS. Treat these as workflow-dependent rather than guaranteed.
