I am trying to make a shank for this ring. I have tried using multiple sets of curves. Split, single span, etc. and none give me a great surface to work with. Network surface was able to generate something, but it was very heavy (even though I used the same type crvs for cross sections) and I had trouble making a transition surface that matched. Here is the file.
