Bruno, from Support, helped me out with a procedure for animating a simple Pantograph by grouping the linkages but, for the Rotations needed, I would like to be able to assign a Pivot for the links without having to also assign an Angle. If you could assign a Translation to one part of the linkage and Pivots to the links they should follow the Translation and it would/should be a lot easier to animate. Call it a "Trailing Rotation" and add it to the list of anim types.
