Specifies the pitch angle for the object. The Pitch angle measures between the x-axis of the object and the X-axis of the global coordinate system in the XZ-plane. This option sets the reference in the model to a line that is the intersection of the vertical plane through the X-axis of the local coordinate system and the active coordinate system horizontal plane. The angle is measured in the positive direction from the horizontal plane in the active coordinate system up direction regardless of the current bearing. Another way to describe pitch is the rotation of the object about its y-axis. Pitch angles are limited to between -90 degrees and +90 degrees, with 0 indicating horizontal.
