I also tried the IFCPropertySetDefinitionCreator, but this doesn't produce any empty propety set either (nor do I know how to write values to it).
The properties for each set, along with ifc_property_set_name, ... The definition for Pset_SpaceCommon is not really required, ... AutoCAD to IFC Conversion Example
Hi @DaveAtSafe, it works well as soon as I use the appearanceSetter and set the attributes as traits really at the beginning of the definition of the object's geometry.
