I have a Vwx file with a certain class structure containing various classes with unique attributes. I'm trying to export it into a dxf of dwg or 3dm where the class structure is converted to layers instead. When I export the drawing, I notice only the classes of objects drawn in the vwx are actually exported. Is there a way to export every single class in a vwx regardless of whether the classes are used in anything drawn? Thanks!
