But on the User side, it's what Revit made use of prior to it's buy-out by AutoDesk. It worked flawlessly, and never gave us trouble with import/export issues. So I don't know how easy the OpenDWG alliance is to work with, or how easy their libraries are to work with from a programming side of things, but I can tell you that the end product, at least in Revit's case, was *perfect* using those tools.
