I used to work for an MSP that primarily serviced architecture firms. Can anyone with real-world CAD experience comment on how this stacks up against AutoCAD and the like? I can't even remember the other one or two major platforms some of our clients used and two quick web searches didn't reveal their names, so maybe they were more fringe than I'd realized.

Autodesk products (AutoCAD, Revit, etc) were an incredible pain to support. Beyond doing its primary job as CAD software, I'm also interested if anyone can comment on how this compares when troubleshooting, upgrading, sharing files from disparate versions, etc?
