I'm working on the "Changing Structural Member Types" Tutorial for Revit '09. It asks me to select from the Type Selector the HSS-Round Hollow Structural Section-Column:HSS20X.0500. The only column options I have are W-Wide Flange-Column: W 10X49 and W 10X33. Can anyone please tell me why this is not in my Type Selector? I tried closing the document and reopening from the Training Files folder, and it did the same thing. I also tried the beams (which is the next step to change), and the same thing happened. The HSS-Hollow Structural Section:HSS8X4X.625 is missing from the Type Selector. Thanks!
If these families don't exist in your template, you will have to load them from your library on disk.
That changes depending on your OS and setup, but it is likely something like:
C:\ProgramData\Autodesk\RAC 2011\Imperial Library
Start the beam/column command, and on the ribbon, select "load family" to navigate.
