[quote="highpockets"]Nope, still confused.
I'm not understanding the 3D model and what it has to do with a single vector.
A picture/sketch, something would help. Sorry to be so dense.
Don't worry John your not the only one
I am not sure if the OP just wants to project a vector cut onto a 3D model or if they want to try & generate a vector from the 3D surface
