Hey ... that gives me an idea ... a jaw jig! We could design one! When you
get something right, it could sense the position your mouth was in and
remember it for next time you are doing that. We'll be rich!
I'm not that good at saving failures. I usually keep on chugg'n till I find
something that's close enough. I will start saving some of them and pass
them along though.
I haven't seen any problems with uneven numbers of control points either;
just don't like having more than I need (get confused easily I guess).
Another problem I run into with lofts is getting the rail geometry in the
right place on rotated profiles. I've been using three-point workplanes but
when you have several profiles sometimes it's a real pain to get the rails
in the right place.Sure would be nice if the 3D sketch command had a
three-point arc tool to make rails with though. Dream on, no?
