Aubin Academy Revit MEP Dataset
It appears that there is a techincal issue with getting the dataset for the Aubin Academy Master Series: Revit MEP 2011 up on the CengageBrain website. I was informed that they were re-posting the files but it seems it is taking a bit longer than anticipated. In the meantime, I have posted them to my site.
You can get the entire dataset as a single Winzip executable file here.
