Revit - Schedule as property sets missing area and perimeter in IFC

[roland3do]

While exporting IFC from Revit our goal is to add only one added property set to IFC. That is, for example, only schedules as property sets and not Revit propery sets, base quantities etc.

Mostly it seems to fulfill its purpose, but revit rooms (IfcSpace) is missing Area and Perimeter properties in IFC.

I made an example of the situation with the Sample project and added screenshots

Does anyknow know what could cause that and what could be the solution?

No

However when mapping parameters with a text file it exports area and perimeter.
