The REVIT video tutorials listed below have been posted here before but I thought some people may want the M4V Podcast version so you can learn REVIT pretty much anywhere using your iPod.
This is a tutorial series on creating a custom architectural Beam as shown above. The lessons learned here can be carried forward to help solve some of your own custom family challenges.
Here are the 'zipped up' iPod formatted files.
Expect more M4V files for REVIT Training to be posted here !
