Phiro:
Thank you very much for your efforts. I really appreciate it. It looks like a very smart way.
I probably need to get it spelled out though sorry :-/. I'm still pretty new in Moi.

In step two - what did you do? Did you join those connected edges and copy them so you have the next step? Did you choose those because together they seemed to be the best approximation for at surface going through the center line?





In the step after you just make a loft it seems when I replicate. In the step after that do you do an offset to make that midpoint line? And the final step why didnt you just make a sweep? But maybe you did?

Again thank you very much.
