Measured Sphere button
Use the Sphere button to measure the diameter, sphericity, and position of the center of a sphere.
To create a measured sphere, you must take a minimum of four hits.
The points to be picked must be uniformly distributed over the surface.
The first four points that are picked must not lie on the same circumference.
The first point should be taken on the pole of the sphere's cup.
The other three points are taken on a circumference.
