Hi Martin
One option is to draw a polyline that consists of several small chords of the circle you desire. The chord wants to be small enough that the "flats" do not show at the largest scale required. Its a little inefficient on storage but works. Something like 30 chords will look smooth unless you need to zoom in a lot. I'd also suggest one data attribute to store the fact you regard it as an arc and another for its radius for report purposes. This is how Ordnance Survey store their arcs, and also how MapInfo and AutoCAD render their arcs for display purposes.
