Pole Axis: This parameter becomes available when the X, Y, and Z axes are enabled in
the Include parameter. Because all points are at a fixed distance from the target or attractor
object (the Pole Axis), the object can be visualized on a sphere of all possible orbits, with
the target object at the center of the sphere. The Pole Axis defines the two points on the
sphere that the orbit must pass through.
• X: The following image illustrates Pole Axis set to X. The light gray box represents the
boundary of the group.
• Y: The following image illustrates Pole Axis set to Y.
• Z: The following image illustrates Pole Axis set to Z.
