I am new to Archicad and I am having issues with the exported model. I have exported the model both in gbxml and IFC4 format to be used in TAS Engineering and Cype softwares. When I import the model, both softwares do not recognise internal partition and slabs of the building, making confusion between internal and external walls/floors. I am aware that both TAS and CYPE probably works better with REVIT at the moment, but I do not understand the issue here. Anyone with the same problem? Could it be zones selection error? I checked the model 100 times....
