Iterative Alignment Error

Hey, friends. Hoping someone can help me. I keep getting an 'Iterative Alignment Error' on my programs and I'm not sure why... I've attached my code and a picture of the CAD I'm working with.

I'm aligning on 3 sample hits on top of 3 bushings pointing in the x
I'm rotating in two bushings into the Z
I'm using one bushing for the origin.

I don't know why it isn't working Disappointed

Save meeeeeeeeeee

  • I just get the prompt "Iterative Alignment Error". If I dimension my pickup features out after my alignment they have a weird "iq#####" something code in their values.

    Sometimes when I try to redo the alignment I'll select the 3-2-1 and when that's done and I go to hit ok to exit the iterative alignment, I get a "3 features must be select to plane on" error.... even though I clearly have 3 features selected.

    The fixture tolerance is just a default I never changed. Should I make it something different? Will it change my results at all?

    I even tried adding surface points off the base as my level and still get the same thing...
  • I don't think I've ever come across a situation like you're describing. I think what that's saying is that the values are extremely large.

    There's nothing in your code that looks wrong. The iterative is set up on the proper axes. The circles seems to be generated appropriately.

    What version of PC-DMIS? My only suggestion at this point is to try starting from scratch in a brand new program. Disappointed
