Hello,
I see this is older, but check out www.cadzation.com.
It is very simple to use, and make great pdf's from AutoCAD, and they have a free trail.
Best of luck,
Hello.
This software at www.cadzation.com has a free trail software to go from DWG to PDF, and you do NOT need the distiller from Abode, (it is all included).
Good luck, Paul
