Here's the part that is baffling me. I have a datum plane in XZ plane. I offset it so it would be on the rear face of the body. To do so I had to add z offset, which I totally don't understand. I thought it would be y offset? Can someone explain this? Have enough problems in normal geometry, seemingly changing the axes to something else is baffling. If I change the angle it appears to be rotating around the y axis. I'd like the rotation point to be around the x axis at a certain z offset. Clearly, I'm confused about this. Can anyone point me in the right direction? I'd greatly appreciate it.
