Remarks

The IRotateTracker interface controls the rotation user interface. After cocreating a RotateTracker object, use the members in the following order: Display, Origin, ClearGeometry, and then one or more calls to either AddGeometry or AddPoint. If you were rotating a single polygon element, you would need just one call to AddGeometry for the element geometry; however, a rotation tracker can handle a group of elements. Use AddPoint for features with marker symbology.
