What both of you have suggested works great for the first part: creating a larger circle using the segment length of the smaller one. But now that that is done, I need to create the arc. When I first posted this I was at work and did not have access to my drawing, but now that I am home I can show you exactly what I am trying to do. I am creating tank tracks but with only two hubs. The issue is that one hub is smaller than the other, hence the 24 and 36 sided circles. Each track has to be the same width, but now I need to copy the rest of the tracks between the tops of the two hubs. Typically the tracks have a small amount of slack that hangs down on the top part of the track, hence the 11 segment arc. I know I am being a perfectionist about it but I want it to look right. Also I would like to maybe convert it into SketchyPhysics later, so I would like it to be precise. Here is the pic of what I have so you can see exactly what I need:

So again, I am trying to make the arc with 11 segments that are all the same size as the line that the arrow is pointing to on the left hand side of the last picture (it is showing ~ 1 31/32"). The variables that I need are either the bulge length or the angles that each segment need to be from one another in order for all 11 segments to fit within the larger chord and be the same.
