(1) Is there a reasonable way to create it with editable faces and (2) have it be a slightly thick, 3d object without collisions along the edges? I tried doing a Boolean modifier for the faces, however, I could not subdivide or loop cut any at all. I am not sure if it is because the vertices on either sides of each "wave" are in much different places.
(3) Finally, it would be nice not to have a zillion subdivisions on the faces or loop cuts along the wave, while maintaining the smoothness.
I created the curved plane using a Path and Bezier curve. I think I could just solidify the curve and then try to fit a seperate polygon along the walls, but this doesn't seem proper.
Any tips would be greatly appreciated. Thanks!
EDIT: clarified question
