I'm looking to create a baroque-esque spiral to be cut with a ShopBot. I've tried creating a spiral and sweeping a half-ellipse around it, and using a loft, but haven't been able to get what I'm looking for. Attached is a general idea of what I want. How should I go about this? Thanks much!
I would Sweep a line as a surface body on a helix and then Extrude to that surface.
