Our factory guys want us to export our flat wooden panel worktop part models as dxf files back to R12 autoCAD settings so they can be cut automatically by machine. The problem we are having is that once we've saved the files as dxfs, autocad and the cutting software isn't recognising them as polylines. Is there an easy way to export a flat panel shaped part made by using cut extrudes, so that it will open in autocad as a polyline?
Also, these tops some times have routs in - for example a hole cut for heat venting, or rebated thinner to accomodate something underneath. Is it possible to represent this in a 2D dxf file? Or should we be looking at getting the factory some more sophisticated software that can automatically interpret a 3D part?
We have tried some of the other macros listed in different topics, but none of them do what we need.
