This paper describes a rectified synthesis method where a rigid body of a six-bar linkage with well-defined transmission angles is guided to pass through four precision positions. The procedure includes the elimination of circuit, branch, and order defects. This is achieved by decomposing the six-bar mechanism into groups of vector pairs called dyads and groups of three vectors called triads. The algebraic method of synthesis can be applied to rectify those chains. Although these defects can be eliminated, it has been a challenging task in the past. The procedure has been implemented for a Watt I crank-driven six-bar linkage in the interactive synthesis package RECSYN.
