Let's say I have two gears, one (Sheet.1) rotates and the other (Sheet.2) rotates at a 50% rate of the first gear. If I set the second gear's angle to be Sheet.2!Angle*0.5, what happens is, as the first first gear approaches 180 (from 360), everything is fine, at 180.1 degrees, the second gear is at 270.05, but as soon as I cross 180, the second gear jumps to 90 degrees. How do I stop this from happening, so that as long as I rotate the first gear, the second gear continues to rotate as it should?
