Circularity/sphericity tolerance (circles, spheres)
Use circularity/sphericity as form tolerance for circles and spheres. This toler-
ance defaults to circularity when the selected feature is a circle and sphericity
when the selected feature is a sphere. A minimum of four points is required for
a circularity tolerance and five points for a sphericity tolerance. The more
points used in the tolerance the more accurate the fianl result.
To perform a circularity tolerance
