How to create sector in ArcObject 10.1? Now I draw one point, two lines, two arks. But I think it is not good. It is differents objects. I need one object.

Well. Now I drawing:

IElementCollection coll = new ElementCollection();
....
CreateSector(mapSector, ref first, ref second, ref third, ref firstInner, ref secondInner, ref thirdInner); // find 3 points on external arc and 3 points on internal arc
....
IElement elementPolygon = CreateSector_Polygon(mapSector, first, second, third, firstInner, secondInner, thirdInner, polygonSectorColor);// create polygon
coll.Add(elementPolygon, -1);
....
// draw sector on the map
Map1.ActiveView.GraphicsContainer.AddElements(coll, 0);
Map1.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, coll, Map1.ActiveView.Extent);
