I'm a jewelry designer and fairly new to Blender... This is my first time asking a question on the stack exchange.
I was trained in Rhino a few years ago and I remember the function "sweep on a rail" which is where you could take a shape / multiple shapes and apply them to your curve (for us jewelry designers, it was a cuff, wire collar, etc.)
I'm having trouble finding the equivalent to that function now. I feel like what I'm trying to do is pretty simple. I want to make an open metal collar (that opens on the front side of neck) that is a half circle tube where the flat side of circle touches your neck at one end then naturally twist 90 degrees to touch your collar bone on other end of necklace (see pic).
So far I've tried the bevel tool in the geometry section as well as a combo of array and curve but I can't seem to get it right.
Any help would be appreciated. I'm happy to share the file as well.
I tried Craig's advice, but this is what's happening now. For some reason the circle the wrong way so it's flat instead of a tube around the curve (collar). Here are some pics.
