You can use the Cylinder icon to measure the diameter, cylindricity, and orientation of the axis of a cylinder oriented in space. The position of the baricenter of the points picked is also calculated.

To create a measured cylinder you must take a minimum of six hits on the cylinder. The points to be picked must be uniformly distributed over the surface. The first three points picked must lie on a plane perpendicular to the main axis.

Example Cylinder with eight points
