Imagine I have a 3D sketch of a potato chip. Imagine the perimeter is fixed in space. Now I want to snap a line to this "potato chip" spline. The only two relations are the two end points of the line having a coincident relation with the spline. Now if I had the ability to tell the line to find its minimum or maximum value, you can see how the line would orient itself accordingly.
Is there a way in which I could achieve this?
Thanks in advance.
