Orientation Constraints
Orientation constraints assign the target's orientation to the object. If the target is a moving part, the object will also be affected by changes to the target's orientation.
The object's orientation and the target's orientation are defined by their pivots, which set their local coordinates. The rotational transformation that is applied to the target's pivot will be applied to the object’s pivot.
Two methods exist for setting different orientations for the object and the target with an orientation constraint:
Modify the orientation of the local pivot for either the object, the target, or both.
Set an orientation offset below the list of constraints. The offset should be provided in X, Y, and Z angles. It will be applied to the object's pivot.
