add a slider to the layer to edit rotation.
name your rectangle “End 2” and paste this in rotation of the sign.
Now you can use a dummy system so that you can parent objects, always auto orient to the layer being called to.
follow2 = “End 2”
diff = sub(position,this_comp.layer(follow2).position);
(Math.atan2(diff[1],diff[0]) * 180/Math.PI) + 180+effect(“Slider Control”)(“Slider”)
