When exporting a Revit file as a CAD format file, you are limited to a number of file types (DWG, DXF, DGN, or SAT). I have experimented with all of them and the obvious choice is to use DWG/DXF and import the file into SW, as SW can handle these more efficiently. This can take a large amount of time, and is not really an option. As I have very limited use of Revit, can anybody offer some advice on this?

thanks,

Phil.
