That was it exactly, regenerated this morning and it's all working perfectly. Thanks for your help.

I'm having an issue programming with X7, I'm doing some 5-axis work and I'm trying to set reference points so I don't swipe the part. My retract works as expected, it goes to a safe location for the tool to swing to position. However, my approach is totally ignored. It shows nothing in backplot or verify or the posted code. Basically the tool starts from my clearance plane, which means taking out the steel casting I'm cutting as the B axis swings around. Any ideas on how I can get a safe start position out of this? Also, home position does nothing.
