Thanks for your suggestions
I'll have to check with the printer.. I believe that they printed from Acrobat and not just reader... Though I never thought to ask that -I will also find out what driver they are using (Thanks for that suggestion as well, islandmon).
The other suggestion the Printer had was to export a .DWG file to them, however, that just seems to give all the 3D information (which then prints out), even though I've saved a file with hidden lines rendered...
Is this also common?
Thanks again
