Runout of Constructed Circles

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.
