Reverse drive constraints action AAAARGHHH!!

[tmox]

I have an angular constraint on a pivoting plate.
I am trying to string together some avi files for a demonstration of the unit.
If i change the constraint from 0 to 15 degrees the plate rotates counter-clockwise. If i drive the constrait from 0 to 15 the plate rotates clockwise. OK, so use -15 degrees............it still rotates clockwise.
If anyone can help, I have a presentation in a few hours and would like to get this resolved.
Thanx in advance for your assistance.

P.S. Can anyone tell me an easy way to string these avi files together. There are a dozen moves altogether.

Here are a couple suggestions that have helped me (but are not really logical).

Make sure the angle is constrained to an origin plane.

change the # of steps (or angle increment)

Change the type of constraint to "directed" angular....but this often times doesn't help.

I've run into similar problems. In the dimension box, try multiplying times -1, i.e. 15 * -1. Sometimes works, sometimes doesn't.
