I'm looking for a way to export the 3D model & custom information of a building on different levels (zone, floor and whole building). The client (Surveyor) asking for cityGML as an end format to share data with the government. FME by Safe is the app that they look for information.
Which setting do I need to modify in IFC manager? Also, how can I include data written in Project Info (AC) to the IFC?
