The forums are full of people discussing various challenges and successes around their use of Bentley BIM technologies, and other building tools as well.
I know this is late, but if you weren't aware, the Mid Continent MicroStation Community is hosting their annual conference in the Kansas City suburbs, and there is a dedicated BIM track.
The track includes sessions around AECOSim Building Designer, Workspace setup, AECOSim Energy Simulation, Visualization, and other topics.
Other tracks include MicroStation, Civil, ProjectWise, Plotting, Management, Potpourri, and the US Army Corps of Engineers.
Please use the attached PDF as a guide to see the great sessions we'll have, and hopefully you can register and be there.
