Autodeskers Chris Yanchar and Julian Gonzalez of the Autodesk Architectural Desktop "ADT" team showed me some really nice examples of the power of their product. Of course I have to mention ADT is built on AutoCAD as a platform for the architectural specific industry.
You can find many awesome examples posted by ADT users in the discussion groups:
Autodesk Architectural Desktop Customer Gallery
Other discussion groups both web based and news reader and hopefully soon by RSS syndicated feeds.
ADT Discssion group list where many ADT Team members also participate in the active discussions with cusomters.
