Millions of people have some experience with polygon modeler, nurbs modeler and whatever else exists... Trust me, there is nothing like Revit modeling tools and the strange mental ray renderer inside revit.... it doesn't belong to any category...For example... There is no history...no subobject handling (at least a decent one) no UVs, no alpha channel or clipmaps no background image...
The other biggest problem is the lack of import/export options in Revit... I've said it before... They don't have a .obj import/export but they can read and write DGN !!!...(I think it's a Bentley format)... Also Revit to Max is not yet 100% error free...

****Btw, I can't import a SAT file from Moi, it sais I have to pass the file through AutoCAD !!! Then I understood I have to check the solid and no 2d geometry and it was ok but there is NOTHING I can do with it... How can I make it a Revit mass?
Some help here please...
