Is this important?
I would imagine so, considering all the parts have datums, but what is the difference from, say, setting a point as Datum A and dimensioning a feature to Datum A, and setting a point and dimensioning a feature to said point?
If you are measuring a point to a point, you don't need to set the Datum Definitions in PC-DMIS. As Vinni said, you would need to set them if you are using Xact Measure and dimensioning a GD&T callout.
Make sure your alignment are rock solid as well. You could be dimensioning something incorrectly if it is not.
