I've got this parametric model that I need to recreate as a poly model, since I want to add a lot of surface detail to make this look like it was constructed from stone and mortar, so I'm thinking I probably need to achieve clean geometry/UVs to be able to paint in those details and add a displacement map to give it more of a textured profile.
In my "parametric prototype" the central tower is a truncated cone, and the spiral ramp was made with a sweep over a tapered helix.
Is there any way I can project the helix onto the surface of the cone to get even cuts in my vertical edges that follow the spiral? I've tried making a Line cut using a copy of the helix that I made editable, but it does a projection all the way through the cone and I'm getting the opposite side of the helix as a cut on the visible side, even when I check the "visible" box.
So far, the closest I've gotten to the result I want was just to use a straight line cut with "Visible" checked so that it only cuts from the side of the view I'm in, then switching to another side and making another straight Line cut. But this does not result in a smooth helical line around the surface, so I would have to slide all the new points by hand into their proper vertical positions on the surface, and as far as I can see the Slide tool only works on one point at a time.
I'm hoping there's a way to project the helix toward the center of the tower and make that smooth spiral cut all the way down on all sides.
Am I missing something or is there just no way to do what I'm attempting in Cinema?
