I started using REVIT shortly after it was acquired by Autodesk which was April 2, 2002.
Hard to believe it's been ten years.
Where did the time go?
I open AutoCAD 2013 now and I hardly know what I am looking at.
I think I have forgotten more about AutoCAD than most people know.
I also assumed that everyone was on REVIT Subscription and running the latest release of REVIT or at worst one version back but after networking with my BIM / CAD manager buddies at the Calgary REVIT User Group I discovered that is no where true.
It seems that many consultants are still using REVIT all the way back to version 2009 !!
