Not just for architectural. It is suitable for all manufacture related designs. As well as exporting something into Revit for 6000$ to put dimensions ? No way :O ??? Not to mention that Revit is a useless product I hate, hate, hate. The company where I used to worked they modelled the Apple Centre some weeks ago by Revit. They couldnt rotate the model at all ! I love Moi ! Dimesions are important even If it is basic. So useful for every documentations when we provide plans to manufacturer. Particularly I mean product design. But. Hatches would be useful too.
