How to convert PDF to DWG files? I just tried do in different ways: 1. PDF -> Acrobat -> Copy and Paste to AutoCAD: It works well, but not quickly enough. 2. Aide PDF to DXF Converter ([URL]http://www.aidecad.com[/URL]): Convert pdf to dxf and save them as DWG. It works well, quickly. BUT you need to pay $ to get it after the free trial period. Is there a conversion free software to convert PDF to DWG directly? Thanks!
