What that means in practice
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: IFC 2x3, IFC4 and BCF. Treat these as workflow-dependent rather than guaranteed.
