The idea was to make a "motion path" figure consisting of two (or more) 3D Bier curves. The motion path figure defines the knots and control points of the curve, and calculates the coordinates of a point moving along the curve. The moving point is body part (actor) "dummy" of the path figure. To move an object on the path, the object is parented to actor "dummy" and then the "Plot" dial is animated.
