  • Scan - Feature Set........

    Can someone explain what I am doing wrong?

    Off-line I created a scan, it is at 0,9,0 with a Ø of 2.8444
    To eliminate outliers I constructed a feature set, now the 'X' is off -.0002 and the diameter is saying it is 1.8898. Am I entering wrong parameters, polar - linear?

    If i report out just the scan, it shows my Ø as measuring .4724.

    Please help!

    I also constructed cyl from the scan-F-, It reports out great, the only thing is that the outliers will cause this to show bad when ran on-line. So I created one from the feature set -F- and, well as you can see, it is no where close to nominal.
