Is it in VA possible when we export to IFC to choose the Level of Geometry and Information (LOG & LOI)? And is it also possible for the representation on the screen and for 2d drawings?
That’s not possible now. VisualARQ objects (and Rhino geometry) don’t have level of detail so they are exported as much detailed as they are. You can just decide whether they are exported or not:
or By Layer, in the IFC Export Options dialog:
In case of LOI, geometry is exported storing all data that has been given, and it is not possible to decide which data stays and which data is not exported.
