During my weekend punt around YouTube found these on the shared Co-ordinate theme - I have no idea what Revit Addict's name is but thank you for sharing these videos with the outside world ;0)
These videos are for in-house training at my firm, Forell/Elsesser Engineers, located in San Francisco CA. Check out our website at http://www.forell.com/. Note, with some videos I have more preparation than others. Still I hope this was helpful. All third party images and programs used are copyrighted. Comment or thumbs up if you want more. Thanks!
Steve Stafford has written about shared coordinates and related issues in the past. This is a re-post of Steves and serves as an additial place I can search for them when I need them again....
