How can I merge two lofts together and thicken it?

This looks like a big departure from the work we did last Wednesday?

I don’t think you can get 17 twists with only 12 frames around the circle. This is 17 twists using @magicteddy’s mob.gh code from that post, with a few tweaks to modify the range of sliders It has 50 “frames” or section lines as opposed to your 12.

Your code doesn’t resemble that at all.
