Hi,

We have setup our Revit model using assemblies. When I use 'IfcExportAs' I can override the AssemblyElement to show as a wall in the ifc output when I fill in 'IfcWall' as the export value. However when I use 'IfcSlab' the AssemblyElement wil not export as a slab but remains a IfcAssemblyElement.

When I dissassemble the assembly and fill in 'IfcSlab' for the slab ifself (it is a structural framing) then the structural framing will be exported as a slab.

Does IfcSlab not work for assemblies or I am missing something?

regards,
Raymond
