Hi, I've made a sketch on a plane that moves along the path of the curved surface, and on this sketch, I've made an arc whose top part is constrained by the path above the curved surface. The goal is to extrude the arc and have it fade out toward the edge. If I move the plane along the path, the sketch does exactly what I want it to, but I can't find a way to extrude it so that it follows the sketch along the path. Can anyone help?
