What was the application that found a path around a closed polygon that didn’t cross the same place twice?
I’m sure you wrote something like this that essentially created the toolpath for machining pockets. I can’t find the post but it could be useful here if applied to a tessellating pattern like the one here.
Is there a travelling salesman type solution too?
