2d Curve - Best-Fit

[[Cl...]]

Using an O-inspect 543. I'm measuring a 2d curve with the camera and the recalling the curve points into 5 separate 2d lines to use for two 45 deg chamfers (reporting angle and length). The curve is in the YZ work-plane. I want to create a best-fit alignment from the curve. Under Evaluation, I created the alignment, then under "Parameters" I ticked translation along Y & Z, & rotation around X, the I use that alignment for each constructed line, in hopes that this will make them more stable. Is this the correct strategy?

I don't see how the best-fit alignment would have any impact on the calculation of lines that are from the Curve themselves. Now... if you want to use that best-fit alignment, and then measure the 2d-lines using the alignment from the Curve, that will make them more robust - I've done this before.

I'm trying to pass a Gage R&R. If this run doesn't work, then I'll try what you suggest. Now as far as what I did;

"then under "Parameters" I ticked translation along Y & Z, & rotation around X". Is that part correct?

I believe so, yes.

Like I said though the best-fit isn't doing anything for you in this case.
