At AU2011, I Took a class led by Aaron Maller with The Beck Group.
The class: AB4532- Autodesk Revit Links, Groups, and Documentation: How to make it Really Work!
The class was quite informative and I was certainly glad to be a part of it. I thought I would share his blog and you'll see the most recent post is regarding the class mentioned above. The Handouts and sample datasets are available for download there as well....enjoy!
