Interested in more MEP content? Probably! You can check out the extension HERE!
This is the text from the Autodesk page:
The Revit MEP® Content Extension provides new content for Revit MEP users. Both Imperial and Metric versions of the content are available for download below, in ZIP format. After download, users can then uncompress the file to the desired content location.
Before You Download
The content files are compressed with their path information included back to the root directory of the folder structure installed with Revit® MEP 2008 Web Update #2. For example, in a default installation of Imperial content, the ZIP file would be uncompressed at:
C:\Documents and Settings\All Users\Application Data\Autodesk\RME 2008\Imperial Library
In this situation, all files will be uncompressed to the correct folders.
