Hi guys, i need help. what are z1 and z2? I set the normal orientation and correct me if I'm wrong but positive mean top and negative mean bottom. When i go to hypermesh,
, but now how can i know if z1 indicate top ,and z2 bottom? Because by default i see top layer z2 and bottom z1. And so i wanted to know what z1 and z2 stand for? if they indicate top or bottom
