I dont do iteratives often, but when i do, i ask you guys for help.
ill post a drawing and i would like some guidelines how to align this.
3 points on A, 2 points on B, 1 point on C?
not really sure how to go about the C one
To report out dimensions sure, but to just measure the part you can use anything you want as long as it’s stable. God save us from engineers who have never measured a part in their lives assigning datum features on prints.

I disagree. It's OK to use points that have easy access for manual alignment to find the part, then do an Iterative alignment in DCC using the Datum Targets. You MUST be aligned to the datum scheme before you start measuring. If not, your results are bogus.
I personally use external alignments for the initial manual alignment. Then an iterative DCC alignment. In the case of this part with small datum features, I would want to make sure it is dialed in pretty close before I did an alignment using them. Hence using the holes and slots first. But I wouldn’t report any dimensions out of that alignment, just using to find the datum features more precisely.
