The 'QuickReturn 2' motionlaw is Not available in the MotionLaw Selector. The 'QuickReturn2' motionlaw is a Rise & Return motionlaw that is continuous in Position, Velocity and Acceleration. Construct the 'QuickReturn 1' motion with two Flexible Polynomial Segments. The first segment is the 'Rise', and the second the 'Return'. Each segment is a 'mirror' of each other. Usually, the segments have an equal duration, but this is not necessary. Continuity at the MidPoint BlendPoint At the midpoint, the Position is maximum [in the image, max P=1], and the Velocity is zero. The Rise segment [below, in Blue] ends with a finite, negative acceleration. The Return segment [below, in Red] starts with the same finite, negative acceleration. Thus, there is acceleration continuity when the segments follow eachother. The Jerk is continuous and zero at the midpoint. [The Jerk is unspecified and not zero at its start an end]. The position graph makes a quickreturn at the midpoint because there is a large negative, but continuous, negative acceleration at the midpoint. See Also: Two Segment 'QuickReturn Motion 1'
