I am trying to open .DWG files dated 2001 in AutoCAD 2010, I received from an Architect and they will not open. I get an error message that says "drawing is invalid file type". I can't believe all the files are corupt so I am wondering if 2010 can go back to R14 or even R12. or do I need another program.
