Runout of Constructed Circles

ArkansasBeeper

Hello Great Gurus (or I guess people with many points, so lame!) 

I am trying to measure the runout of a constructed circle, seemingly the Demon things I should not be doing that as its not an option on the list of features.

I am currently creating a circle at the intersection between a constructed cone and a constructed plane.

 

Should be right there at the bottom of the list. All of the other constructed circles are.
But to be fair, I think the last time I did this was with 2016, which would let you measure almost anything. 

Any ideas?

    A lot of CMM software will not allow form or eccentricity error doing this directly.  Do this:  measured line (autofeature) on cone, measured line (autofeature) on plane, intersect point.  Paste that with a pattern around axis.  Now with all those intersect points, you can get everything you want, at least in the less stupid versions of PC-DMIS

    Thanks! That's a great method too! 

    If I hadn't already committed to points for data acquisition I would have that a shot. Sadly in order to future proof our programs for the engineering department that likes to play God and say "what would it look like if we did this" 3 months after we have measured the parts... A lot of our data is captured as points so they can easily be manipulated after the fact. "What would it look like if you just removed the 2 worst hits?" and things like that are the norm here.
