I am not too worried on the process as much on the bunch of curves and locators lying around. Just not too comfy with so many of these in the outliner. I plan to have a chain with over 100 links and that would have about 100 curves and locators all over the place. Very crowded!!!. Wondering if I can use only one curve and one locator to achive this. I wrote a mel script earlier for motion path for an escalator with about 40 steps, so could use a similar one to duplicate the links. One other problem with the above process is that after a couple of rotations of the locator (more than 360), the links start to drift apart ?? Not sure why this is happening. Rgds, GP
