#### Creating a Measured Cylinder

| Use the Cylinder icon to measure the diameter, cylindricity, and orientation of the axis of a cylinder oriented in space. The position of the barycenter 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

Note: Be aware that certain patterns of points (such as two rows of three equally spaced points or two rows of four equally spaced points) result in multiple ways to construct or measure a cylinder, and PC-DMIS's Best Fit algorithm may construct or measure the cylinder using an unexpected solution. For best results, measured or constructed cylinders should use a pattern of points that will eliminate unwanted solutions.
