Hmmm - need more info - can you post the relevant code? SurfaceClosestPoint will return a parameter, not a point 3d, in case that helps.

Looks like you think you have a point3d object that you are passing into a function, but in reality it’s some kind of list (which looks bizarre…) Can you put a breakpoint just before the error and look what your variables are?
