Thanks for your reply! I want to draw a curved surface dynamic, like the function Mesure area in skyline. now i have the profile line of the curved surface,but just lines,not a polygon or a surface. my issue is: how to display the profile line to be a enclosed area, not lines. use OverlayNode??
Thank you!
