There is a new free online community for AutoCAD users named AutoCAD Exchange http://autocad.autodesk.com
This new site by Autodesk will feature many videos, Ask the Expert sessions, featured customers like Hollywood's Eddie Paul. There will also be some fun content like The TeknoChronicles of Z series, and even Roger Penwill CAD related cartoons. There is also the ability for members to share content and AutoCAD tips.
It should be another great resource for all AutoCAD users to bookmark and join.
There is also a CAD Management series I filmed in February with CAD Management guru Robert Green. It is amazing how they say the camera adds ten pounds to you, but I see it can also make me look hair challenged especially when appearing with Robert Green's healthy full head of hair. ;-)
Quite a bit in the AutoCAD Exchange community, and more as it begins to grow.
Cheers,
Shaan
