RPC trees not rendering in revit 2009

[jwilhelm]

I placed a couple rpc trees in my model, the stick figure shows up but when I render there is nothing there, any ideas?

I'm having a similar problem - I downloaded an RPC tree from archvision, and can't get it to show up in the model.

I placed it in the RPCs folder on my C drive, had to change the name to get it to show up on the list of trees, and can't seem to get more than a cube showing up in hidden lines. When I render, nothing shows up at all. Anybody know what I'm doing wrong here?
