Lutz,
Thanks for the suggestion. After experimenting for some time, I realized
that the "orbit" function won't work for this particular application.
However, I discovered that I could make a cylinder, click "local
coordinates", and translate it away from the z-axis, then in the "duplicate"
dialog box, click rotation 0, 0, 6, and translation 0, 0, .5. This makes a
helix with each segment having its origin on the z-axis. That way when I
rotate the first cylinder, all the rest of them rotate in relation to the
axis of the helix. It took tweeking the rotation in x, y and z to get the
desired results, but it works!
I posted the new file (snakeything2) in moray.
Another Question: Is it possible to incorporate I.K. into this?
Thank you,
Steve Shelby
