Just wrapped up some consulting work with 4D Technologies and Matt Murphy's group - I helped them with the AutoCAD MEP 2012 tutorial series. A lot of after hours and weekend work, but I think you guys will really like it. The lesson includes about 12 hours of material, from fundamentals to advanced topics, including project navigator for MEP, schematics, modeling MEP systems, creating custom content and more.
Keep an eye on the CADLearning website - the sessions will be posted soon. For more details, go to http://www.cadlearning.com/.
