I am just wondering WHY is autodesk not willing to make Revit export (and import) ALL of the AutoCAD format? (DWG2000,2004,2002,R14,R13..etc)
I mean, A LOT (that's more than autodesk would admit I am sure) are still using R14, not many upgraded past 2002 and it's obvious Revit should have supported older version of format since Revit is now an autoDesk family of product. What amazed me is that the rival product ArchiCAD can export a lot MORE format (including older DWG formats) than Revit can.....
