Hold on, doesn't that just prove maps are flat? If the shortest path curves on a globe, @jessel35, but looks straight on a flat map, maybe the map is right. That ruler test seems backwards to me.

Wait, you wrote whole scripts for it? That's wild... I could never be that patient. It makes sense though, like trying to explain a dream to someone who wasn't there. No wonder it got confused.

Nah, you're overthinking it. Just set the depth right and you get a clean finish every time, even on MDF.
