(PC-DMIS - Feature)

I could see where this is beneficial for measuring the position of arcs that are less than 180 degrees or circles with poor form. You could use a radius gage, gage pin or another more accurate method to determine size, then enter that size as a variable in CMM-MANAGER to force a best-fit to determine the position.FIXED_RAD Fixed Radius – This calculation type creates a circle of a given diameter, positioned so that the maximal radial distance from the data points to the circle is minimized. It is similar to the Max/Min math used in the MIN_SEP calculation except that,since the diameter is known in advance, the radius cannot vary. Only the circle's position is allowed to vary.

Thanks,
