update I got it to work. But it is unsatisfactory for my purpose here. It would be really great if you could select which point on the geometry that you are dropping hits the surface of the curved substrate. As you can see from this screenshot (maybe), here, it is the left side of the squares that defined the drop point. this results on half of the object being nested into the geometry, and half of them just touching a corner.
@ntx dave Hmm, I'll give it a shot.
