We have a client dealing with a very demanding BIM convention, and I would be more than happy if anyone could help me with this.   Q1 When exporting a project as an IFC Project, whatever are the units settings in the Vectorworks files, the units in the IFC file seem to be always millimeters. Is there a way to change this or it is a default setting? If yes: Where and how? If no: How are your clients dealing with this when merging with files coming from Revit?
