This morning I tried to upload an AutoCAD2011 drawing to Shapeways for the first time. It didn't work.
Following the instructions on http://www.shapeways.com/tutorials/converting-with-accutrans -3d, I saved my drawing in a DXF-file and I downloaded the Accutrans programme. It still doesn't work.
Accutrans doesn't recognise 3D Solids.
"3DSOLID, BODY and REGIONS are ACIS entries that are NOT converted" Than it says "Export the drawing from AutoCAD as a 3DS file"
Unfortunatly that is not an option in my Export-menu. Or I can't find it.
