Hi Danny,

Yeah that should be feasible - I 've added it to my todo list for v3 tuneup stuff, I'll probably be working on some of that list for the 2nd v3 beta.

For now the easiest way to tune up curves like that is probably to go to a side elevation view and use the edit frame - when you grab a corner of the edit frame and move it downwards you'll get a "flat" snap. If you don't get a flat snap it means it was already flat.

Anyway when you use the edit frame you won't have 2 sets of curves to deal with, it edits the curves in place.
