Hi mdc, thanks for the tip. That works better than the spin, because you can set a true value--like I was talking about in Lightwave. The way I did it was to just rotate 90 degrees the first time, then set it to 179, then -90, then back to zero. I am talking about just keyframes here, I didnt see you suggestion on the rotate modifier until now. Once these keyframes are created its a matter of squashing or stretching them to decide how fast it should complete one rotation. Then once that is set, its a matter of marquee selecting the keyframes and Alt dragging copies of them. Not too rough, but could be easier with the implementation of greater than 180 degree rotation. Still possible, just an extra step. However, with your tip and using the spline curve editor, I can do the same thing in two easy steps. Thanks again. Donnie
