3d best fit, iterative or ?

[jaca_232]

Hello.
I am having some problem with the alignment of this part im gonna post a sketch and and my routine to see if I can get some help.

what I have done so far I have locate the part using a rough 6 vector point 3d best fit. then I used my datum target location per the sketch and took new hits and align to these new vector points and create a plane on datum b since there is no target point there and did another 3d best to 3 vector points for datum A, 1 vector point for datum c and a plane for datum b select all of these.. best fit method is vector least square... but problem is I don't know if this is correct.

[vpt.se]

Datum A as plane with three hits, take the hits where the local datum targets are located.
Datum B as a "regular" plane.
Datum C as vector point, make sure to take the hit where the local datum target is located.

Align with A as primary and zero in whatever axis you selected as primary.
B as secondary and zero in the second axis.
C as zero in the third axis.
