IFCExport not follow the object IFC clasification and hierarchy

[kamil_konecny]

Hello,
I have two questions:
1. Object not follow the IFC clasification
I have wall element as the result of our application all plates and timbers are converted to masselements and they get the Object clasification by the IFC standard so plates are marked as IfcPlate, horizontal timbers as IfcBeam and vertical timbers as IfcColumns. But after I export it to IFC the output file recognise the PLATE object but the beams and columns are exported as BUILDINGELEMENTPROXY.
If I insert to the drawing column or beam as AEC object it export it to IFC correctly.

Is there any way how to set the classification of the masselement object to be exported as beam or column? There is no was how to convert solid or masselement to beam or column.

2. Is there any way how to define hierarchy of the objects for IFC output. I have element with frame, timbering and several plate layers. Is there any way how to define it and export correctly to IFC?

     Thanks a lot Kamil
