How to convert .vwx to .dwg format.
To reliably export/convert VectorWorks Design Files directly to AutoCAD Drawing format (.vwx to .dwg conversion), you will need to use the VectorWorks software itself. This seems to be the only program capable of converting .vwx to .dwg, since AutoCAD, and other similar CAD/3D modeling tools, do not support VectorWorks graphics by Nemetschek (.vwx).
