Trying to report a runout of a surface to a surface and a face using xact measure seems to give me the right deviation but if I turn or graphics it seems like the error/vector is flipped. If I report it as a parallelism which is what it seems to be reporting at anyways it matches what I see on the machine using indicators. looks like axial runout is just like the hole concentricity being report as position. any more insight would be helpful.
Thinking this may be a glich

Runout requires a primary datum that's a centerline/centerpoint, a surface cannot be datum for runout.
So my datum -A- is a surface
datum -B- is a bore
and its runout of a back surface which is parallel to -A-
runout to -A-B-

It seems your #1 problem is a graphics arrow and your #2 problem is that unless you are spinning the part clamped to the A plane but rotating around B bore center you're not going to see the same deviation. Just running the indicator over a motionless part is parallelism - although the results should not be too much different if you're sweeping over the whole surface and the part is not mangled. How much different are your results?

Yeah definitely something you do not see everyday, I have not had the time to see if putting the bore -B-(circle) so no axis as primary too see if it would fix my graphics issues or not hope to try it out later today. I know its not "right" but I'm thinking it will give me the same deviation and may fix my graphics which would be nice! thanks for the help.
