I have two fairly simple shapes. The ‘pipe’ is my cutting tool - I am trying to cut a panel line into the larger piece. These are pretty simple shapes and as you can see I was able to cut part of the panel line out of the piece.
I have included three curves - the green curve represents the top of the piece I’m trying to cut, the black curve is the bottom and the magenta curve is the one used to make the pipe for cutting.
