Hi Norway. In my company, in Portugal, we are about to use a product named "Autodesk AutoCAD Revit Series - Systems Plus 2". It contains Revit Systems 2 (which contains some architectural and structural tools) and also Autodesk Building Systems, that runs on Architectural Desktop, that, in turn, runs on AutoCAD. So you can use each of these procuts individually: Revit Systems 2; ABS, Architectural Desktop, and AutoCAD.
