The problem is even when I am rendering my model.. using 'hypershot' for example.. the curved plane comes out still decent.. i can still see the faceted edges.. I have tried using the polygon tool and making a 60 sided polygon which looks a lot better than the circle itself.. but that isnt the point..

Whenever i Make any curve or a circle in sketchup it does not give me a clean curve. In case of a circle it actually draws a 25 sided polygon. This is a great pain which is actually pulling me away from such a beautiful software.. please help...
