I'm wanting to know if there is a function to measure between random points on a file. i saw an image on google images that showed this, but have found nothing else. i just want to know bc i want to measure points on my armour build and brace the correct shape. i'm also wondering if my back is to big. i followed someone idea of measure from my lowest rib to my adams apple and my iron man mk vi chest scale came to 30.something. i don't want to fiberglass if it's to big and my gf wasn't much help when i put it on. Thanks for any help and if my cast aluminum parts work i'll be more than happy to share info.
