Wall-based IfcOpeningElements from doors and windows behaving differently

Open andydandy74 opened this issue 1 year ago • 2 comments

Looks like IfcOpeningElement objects generated from doors or windows do not behave the same way as those generated from wall-hosted Generic Model void cut families (exported as IfcBuildingElementProxy):

  • Property set Pset_OpeningElementCommon is not exported.
  • Base quantities are not exported
  • IfcRectangleProfileDef.ProfileName not exported (Yes, I know that's an optional attribute, but it exports for the Generic Model openings so why not here, too? Solibri seems to use either this property or the opening's Reference attribute - also not exported - for structuring its model browser, see screenshot below)

Would be great if the export behaviour could be consistent for all wall based openings.

  • Exporter: 23.2.5
  • Tried IFC2x3CV2.0 & IFC4RVArch.
  • Tried old and new shared parameters

BaseQuantities issue fixed in 24.2, but still no Pset
