Hey All.

So I'm trying to create a recessed design in the shank of a ring. I'd like it to run from the top shoulder of the shank all the way to the base. I tried drawing the objects to the approximate length of half the shank but that didn't work so I scaled it down considerably but am still not getting the desired result.






Could someone please weigh in on what I'm doing wrong?
Many thanks in advance.
Gunter
