Runout Experts needed...

I have 2 circles that I scanned. I drew a line between the 2 and that is being used as my Datum. Can runout be measured using a line drawn between to circles? I was told that using cones makes it nearly impossible to get good runout data.
Parents
  • Yes. I do this a lot. But not through just two circles.

    I have many turned parts where -A- is an outside diameter, -B- is a different sized outside diameter, and there is GD&T all over my print that says '"Runout of a certain diameter A-B".

    I will measure three individual autocircles on -A-. Three individual autocircles on -B-. Put a point at the center of each circle. Construct a 3D line through the six points. Then..Insert an alignment....Level to Line A-B..Translate X and Y to Line A-B, Translate Z to a plane/point where I want it.

    If you want to see some sample code LMK.
