Cone layout tool
I guess I should have explained better.
Imagine rolling up the cone with the rod as the central axis. Notice that the position of the pens on the rod are equal to the total height of the cone and the cut off part. Usually known. The distance of the pen from the rod is the cone radius. Also usually known. The wheel goes where ever it needs to touch and rotate. One full revolution of the wheel is a full 360 degrees for the cone. If it is still unclear, I can do a video.
