Im working on a school project of mine, where I want to create a Boardgame using a 3D landscape.

I was able to create the 3D Landscape, but now I want to cut holes for leds to go into, along a curve on the surface.

I got that working, sort of, I am able to cut the holes through the part, along the curve, but I also want the holes to be tangent to the 3D surface, they lie on.

If I try to select the Face normal in the curve driven pattern feauture (which is used for that exact puropse, as far as I understand), I cannot select the knitted surface, I used to draw the 3D spline on.

I really hope someone is able to help me with this problem.

Thanks allerady!

totally forgot to add the part file...
