Very cool construction there Jesse, I'm glad you're finding good uses for these new options! The end result looks great!

I was messing around with a couple of your steps, and it looks like in some stages the rails have been doubled. I mean if you run separate on one rail you can pull apart 2 different overlapped pieces, they kind of fold back on themselves.

I should see if I can detect this type of thing in Join to avoid making that.
