• RelativeX1[cnum, point1, point2, dist] constrains the global X coordinate of point1 to be dist units greater than the global X coordinate of point2.
• RelativeX1 constrains one degree of freedom.
• If point2 is omitted, the offset distance is measured relative to the global origin.
• Note that a RelativeX1 constraint applied between two points on nonground bodies still introduces an implicit kinematic relationship with the ground body because the direction of measurement is in the global reference frame. This can introduce spurious reaction moments to the model. Use DirectedDistance1 to avoid this.
