Can this tutorial help me?

I've found this great tutorial on iterative alignment which was posted on this forum, http://cmmquarterly.mbccmm.com/index.php/training/pc-dmis/30-alignments-how-to and I've read it 10 times, but I'm not sure how it can lend itself to my current sheet metal part.

This is a rough representation of the part in question. Iterative_example.pdf

I can't seem to wrap my head around how I can pick 3 vector points as per the tutorial vs the print showing 3 points on 2 planes, and that it is still Datum -A-. Is it really that simple? Does iterative do all the work?

I've got this working by either using 6 vector points, and just got it working with the 3 vector points as well as 2 circles, but my main question now is, how do I create Datum -A- using those 3 vector points? I have 6 features on this part print that are Position Dimension, 1.0, A|B|C.

I get the B and C datums, they're just holes and I know how to assign them using "Datum Definition" but how do I define A1, A2 and A3 as DATUM -A-?
