Description

### Inquiry description

Hi, I would like to export a user-defined property set with combined parameters from Revit. The combined parameter should contain properties of the element + room properties. Unfortunately, this does not seem to be possible via the Schedules, as the room information is not transferred to the IFC. Is there perhaps another possibility via the UserDefinedPropertySet TXT files and the parameter expression?

Research direction

Start by reviewing the UserDefinedPropertySet TXT files and parameter-expression support involved in IFC export, using the reported Revit 2024 and IFC for Revit 24.x versions. Reproduce the export with element and room properties, then determine whether combined parameters are supported; done means the capability is implemented or its supported limitation is clearly documented.
