@spikeyxxx Thanks a bunch ! I’m still gonna have to think a little more about how to do the math but i get it overall. Feeling a little silly too now lol. I felt like there was something there i was missing with the edges but couldnt put my finger on it . My math is rusty but pretty solid but I’m just beginning to learn to think about this stuff – edges , vertices & such & combine that with the math. Again thanks to you & silentheart00.
