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

  • I'll look back at it again in the morning but I tried doing an iterative alignment with 7 points for the sake of simplicity since it is my first time using them but when I run it I get "Iterative Alignment Error".

    Here's a copy of my code. It's super basic right now because I didn't want to bother with formatting if I couldn't even get it to work.
