Driven Constraint - folding sequence

[Anonymous]

I'm attempting to simulate (animate) a folding sequence for a plastic cover
of sorts which I've designed. The cover is in 5 sections with a scored
relief (grooves) dividing each. I've set up a trial assembly starting with
2 extruded sections mated on edge, with an angle constraint. Neither part
is grounded. When driving the angle constraint, the program determines which
part to move, which remains staintionary; how so? I need to eventually have
all sections fold in a certain order, at set angles.

Any thoughts?
