Polar Points, Vectors and Variables

ELaFever2
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?

  • If your using assignments then I don't think pasting with pattern would work because its going to keep those nominal locked. You could copy the code, go into edit pattern, tell it to copy one time at 0 degrees, paste with pattern, then stick an alignment rotating 40° and tell it "NO". That should move everything over to the next blade and retain your nominals. If you don't use the assignments and just key in the nominals you could pattern it all the way around and it would work just fine but your noms at all the other blades would be whacky looking.
