Polar Points, Vectors and Variables

Hey gurus,

I must measure impeller blades (9) and have been given a chart of X, Y, Z locations for points. The chart is only for the points on one blade. In my code below I have an example of how I am maintaining the nominals and expanding the points to the other blades.

What I am having a problem with is having the I, J, K vectors adjust along the same lines as X, Y, Z. Can anyone help me figure this out?
Or let me know of another way?

Thank you all who have weighed in so far. I am currently working offline and the model I am using is the original. The part has had about 10 revs and engineering deemed it was easier to have charts for inspection points (orangeish points in pic) and update these than changing the model. There about 60 points on the green surface and 40 on the brown, about 100 points per blade which makes about 900 total. The greenish pt A_1 is X, Y, Z from the chart, and its not on the surface anymore, so I'm not sure if the vectors are actually right (so good data is an issue at this point).

Currently this is proto code, as such the naming is temporary, I believe this is the first time hearing not to start names with numbers. My goal it to make sure all the points on the the blades correspond to each other before expanding it. The point in using the variables the way I am is so that because I'm not sure what the proper vectors are or in the future when/if engineering changes the noms on the chart again, all it will take is a few keystrokes to change the variable and 9 points will be updated at a time.

I wish I could Loop, but the powers that be don't like it because it creates "virtual data and features". They want if they need to, to be able to open a program and to scroll thru the edit window to the features in question. So that means in this case they want to be able to see all 900 points for all the blades. But since they sign my checks which allow me to have a roof over my head, food on my plate, and alcohol in my glass to deal with decisions like that, I'm going with it . . . for now. Hopefully in the future I can convince them otherwise.

And that's why it sucks that I wont be able to use JEFMAN's code for the final program. But I did try it, the yellow points in the pic where created by it. The issue I am having with it is that the I, J, K vectors are 0, 0, 1 so the probe is not approaching nominally to the surface.

How do I get the image to a viewable size?
