What is going on with my alignment

[[Th...]]

I'm running in simulation so actual and nominal are the same. My alignment is a surface -A-, a cylinder -B- and another surface.

Simulation gave me Z nominal and actual to be same from surrface -A-. but when I call out the position on the same intersection, the Z is way off. why?

Fill other bases with Plane A

Post a screen shot of your base alignment.

I always fill all Datums in GT&T characteristics. Calypso has done weird calculations, or none, when Datums are blank.

Or try a secondary alignment using -A-.

Yeah, I'm pretty sure Calypso uses the base alignment features as implicit datum features when those fields are left blank. I think you can fill in the secondary and tertiary datum features with the intersection that's being evaluated.

Filling up the slots with datums didn't change anything. What I did was change to a different base alignment and then changing back to the original alignment fixed the problem...
