Hi, while transforming our application to be schema-independent by using the EntityCreator following Objects are missing: - IfcMaterialProperties - IfcIndexedPolyCurve - IfcLightFixture - IfcTriangulatedFaceSet - IndexedPolygonalFace - PolygonalFaceSet - IfcCartesianPointList2D...

Thank you for the examples! I experimented with the "Compile Time Approach" and could cover my use-cases. To avoid down casts from the more general _IIfcFlowTerminal_ for later IFC-schemes, we...
