Hi Burr, well definitely the issue that you mentioned is something to look out for. It is easy to select a "curve" object instead of an "edge" object, especially since many construction techniques will put an edge of the resulting solid in the same spot as where your original generating curve was at.

It's probably one of the easiest areas to get tripped up on in MoI currently.

At some point I'm going to need to try and improve that situation... It's just a difficult thing to handle without popping up some kind of additional UI which I have tried to avoid as much as possible up to now.
