Hello,
i am trying same thing with a stl. But i try to build a offset surface wuch will be the tiilpath for end ballmill.
Slicing through the model is very easy. If you slice along the z- axis take any z coo you want. Then sub fro, every triangle this z value. If you get for a corners of the triangle the same sign (+ or -) this will nit cit the plan. If the a different you must calculate the crossingpoints from the triangle edge and the plan. This point will give a line on the plan. U can look fir the source if you want. Written in C.
