Ever since R5, driven angular dimensions get screwed up after some other
dimension is edited and it causes the driven angular dim to change. It used
to be that they would flip and display 360° minus the angle. Now in R6,
they display either the 360° - angle, or 180° - angle, or even angle - 180°
See the screen shot I put in the CF files.
For this reason, I can't reference a driven angular dimension to define a
new dimension. I'll add this to my christmas wish list. Can it be fixed.
