About model and data exchange with 3rd party solutions: Revit, Solibri, dRofus, Bluebeam, structural analysis solutions, and IFC, BCF and DXF/DWG-based exchange, etc.
I've installed ArchiCAD 10, haven't updated to key from 9 yet, but I noticed that all the Extras that were in 9 are not in 10. I use the Roof surfacer quite a bit. Is this something that I'd have to purchase separately? If so, where would I get it?
