What you're seeing is correct.  The boundary of a true circle only has two points, the point where it begins and the point where it ends.  Because it is a curve there are no points in between.  Because it is a circle, the start point and end point have the same coordinates.

I moved this thread here, to ArcObjects SDK, because it appeared to be the most appropriate location. If you feel that's incorrect, please let me know.

I believe you'll have to call IPolycurve's Densify or one of the similar methods that convert the circular arc into a densified line.
