I'm designing a series of ships which have a scanner receiver oscillate round the edge of a saucer. I can get the oscillation to go clockwise, but it won't go counter-clockwise. I can set the speed, and the angle of turn using the red oscillation arrow, which sets it going back and forth starting clockwise. I assume the green oscillation arrow SHOULD start it with the 1st move being counter-clockwise, but the green arrow actually has no effect at all. The scanner receiver is not sitting on the hard point which it is rotating around, but is some distance away. The hardpoint is the center of the saucer that the receiver is on.

Is there any way to start with the 1st oscillation going counter clockwise?

Cheers
