Hi all - I'm wondering how CMM manager handles datum simulation.  Coming from a PC-DMIS background, datums (and considered features) are handled in the geometric tolerance window where you can choose between "default," which uses the actual mating envelope of the feature so that it's considered similarly to a hard gage, and "LSQ" (and we all know what that is).  

I know that in the features themselves we can choose the math type (max insc, min circ, lsq, etc), so is that where we should apply the datum math?  Or is there an algorithm behind the scenes already happening when applying GDT commands?

Any insight is appreciated!
