In IFC4, Revit still uses deprecated IfcPresentationStyleAssignment and doesn't support IfcPresentationStyle

Open Moult opened this issue 5 years ago • 2 comments

It should use IfcPresentationStyle instead. This means that IFC4 exports from other BIM applications, when imported into Revit, do not have colours. It also leads to invalid IFC4 exports which cannot be read in other BIM applications.

The proper behaviour is for IFC2X3 Revit to support both IfcPresentationStyleAssignment and IfcPresentationStyle. In IFC4 it should only support IfcPresentationStyle.

This still seems present in October 2024.
