I guess you have skipped one or both of those definitions. When you open the DWG in another program you should define again how many inches or millimeters one DWG unit presents. When you export as DWG 2004 in Illustrator you should define how many inches or millimeters one DWG unit is going to present. Illustrator's layer structure can vanish as well as all effects. It was the native format for AutoCAD versions which appeared in 2004.2006.ĭo not expect right colors nor stroke widths when you open the exported DWG. As far as I know, Illustrator CS5.1 doesn't know newer DWG versions than 2004.



Your Illustrator knows only few of existing DWG versions. DWG isn't a solid thing, it has been changed when new AutoCAD versions have appeared.
