Hello,
Acad 2011 will not open a dwg file created by Illustrator CS5. It only flashes a quick message "namespace for closing document is not found".
Acad 2010 will open the same dwg file without problem.
Does anyone know how to get 2011 to open such a drawing file? Eventually I don't think I'll have the option to open these files in 2010.
Thank you.
