I'm not following this at all. The path of "orby" doesn't sound like it's smooth, it sounds like it is like there's a jump in position from the bottom of B to the top of A. Logically I'd expect the path of "orby" to be more like a figure eight. If that's the case maybe I can help. A screen shot or a sample movie would also help. I'm not real sure what you're trying to do.

Yeah sorry for the poor description, thats what I want, orby does a continuous smooth figure 8 around A and B, where ever they are

Is there a way to attach an image to the post? Or do you have to have it some place that you setup and then link it?

You need to place it somewhere and link. I think I've got the idea. This is is a challenge. If I get some time this evening I'll try and put something together. It may make a great tutorial on advanced expressions.

Ha haa, a challenge it is then sir! A digital glove to the cheek of sorts. :-)

I know I would love to see such a tutorial, and I'm sure many others would find it helpful as well. (and certainly your loved ones will gladly sacrifice their time with you to enable your philanthropic acts...)

As for the lack of attachments, 'boo' to adobe forums. Why dont they use the same good forum gear as everyone else? like cgtalk.com and www.newtek.com/forums/ Good thing theres so many fine folks here to make up for it.

Not scared off, just on a huge project with a hard deadline.

I hope I didn't scare you off with my boisterous response.

I really would appreciate any help I can get on the subject.
even just a description of how you would go about it...

My preferred method would be to hand animate the 6 keyframes at the top, bottom, and sides of the two circles, and then use an expression to cycle through those positions relative to the circles.

But I imagine it could be done more elegantly with high school trig that I don't remember.

ohms for the poor, sir
