I have information from my sources
Apparently there are some seconds missing in this video. In those missing sequences the user merges all IFCs in Archicad and then does an IFC Export.
This would make then sense in Solibri, why there is only one IfcProject and the structure develops.
I have tried many ways to see in Solibri just one structure. On the other hand, I believe that Solibri is not design to simulate a CDE where you would probably see this single structure of the project.
So, the case is half closed
