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.

SECTION 9-2
Runout is the tol. used to control the function relationship of 1 or more features to a datum axis established from a datum feature.
Shlag, the question posed is worded rather oddly. "Can runout be measured using a line drawn between to circles?"
The answer is No. Runout cannot be MEASURED using a line. Never ever. Runout must be measured as we've both clarified.
DATUM ALIGNMENT can be established with a line drawn between two circles, then runout can be measured circumferentially, relative to that line...
--you can't MEASURE (aka quantify variation numerically) runout with an axis line.
