I have a small circle in SDE which I'm trying to extract through ArcObjects into well-known-binary (for later import into other systems).
Using the IWkb interface I can obtain the WKB, but it comes out as a PolyLine with 2 points - both exactly the same. I've hand parsed the WKB to confirm this is what ArcObjects is returning.
Are there any ways to get ArcObjects to export circles as WKB and maintain the circle? e.g. as a CircularString or similar.
I'm using ArcObjects 9.3.
