I have a 3d curve, where all points lie in one plane (s. example below).
I would like to fill out the plane space under the curve as far as the x-y plane. Tryed mesh3d for this purpose, but cannot figure it out.
When I place the mesh3d in the x-y plane (horizontaly), it works fine. When I try to put it verticaly (as required in the example), it seems not to work.
