Hi, every one!

I want draw sectors in Network Optimization filed, each site commonly has three sectors, they are with different radius and angles, so how can I draw sectors using MapWinGIS, if I treate them as Point symbol, then how can I get different angle and radius? If I treate them as Polygon object, then when I sacle the map,I need the size of polygon not change with the map scale, how can I realize if?

Anyone who can help me, thanks!
