Position Constraints
Position constraints assign the target's position to the object. If the target is a moving part, the object will also be affected by the changes to the target's position.
To avoid having two objects that occupy the same position in the 3D world, assign an offset to the constrained object. An offset is defined below the list of constraints using the XYZ coordinates to express the difference between the target's position and the object's position. When the target is repositioned, the object will also be repositioned and the offset distance will be maintained.
