I have been trying to follow their instructions on this, as well without any luck. I have a handrail bracket I would like to have as a user part. Not too much more than a bent bar with a round plate, but I cannot make it a user part. Should it be a 3D model? Mesh? Block? It just says to select objects... and nothing seems to work. When I try "define new" using the block method, nothing happens. It's like I didn't even click the button.
Basically, I think it's this GUI that is confusing and the lack of instruction on how to doesn't help. Anyone figure this out yet?
