Auto Probe Compensation

Auto Probe Compensation

Has anyone dealt with this before? I am currently checking 2 similar parts, using .igs models. One part went smoothly, while running the second I get this message on any slot that I try to measure. If I select OK, it will continue measuring the other features and then report a slot width 2.5 inches narrower than it actually is. Running 3.10. I have tried starting from scratch and creating a new program, with the same results. I am going to try restarting everything, and hopefully someone has some advise on how to work through this.
