Help aligning to a part (yes, another one of these posts)

Dsturgeon
Hey guys,

I've been trying to align to this part for the better part of today and I'm coming up with nothing.

Best fits using anywhere from 6 to 19 points end up with T values varying upwards of .100" across the side edges (the critical feature) when it's obviously not that far off.



There's pretty much nothing flat on the part that I can really use.

The drawing has pretty much nothing on it except hole diameter and a .010" Profile of the Surface call out.

Any help Dmis gurus?

Edit: Also I might not be using the Best Fit window totally correct. I've never really had any luck with it but I pretty much just open it, select all my points, make sure "3D" is selected, and hit okay.

Thanks
-Daniel

  • Enter fixture tolerance (i.e. 0.030" for manual alignment).

    When selecting vector points there are "rules".
    The vectors for the first 3 points must be approx. parallel. The 4th and 5th points must have vectors approx. perpend to the
    first 3 points. Can you use the side wall? Like front to back or left to right.

    Finally use 3 sample hits with the circle.
