Secondary alignment vs single Datum's

[[Cl...]]

I've noticed that if I use a secondary alignment for a true position characteristic, I get one result. If I populate
that same characteristic with the same three datum's, I sometimes get a slightly different result. Why is this?

It is possibly that you have your Outer Tangential and ISO 5459 settings active when you select your datum features and your secondary alignment is defaulting to LSQ and not constrained to ISO 5459

Thanks, yes I do.

DRF follows the can-may-must rule. Alignments do not unless you are selecting the features off the model.
