Hi Ekaterina, Thanks for the clue. I am at present doing the round trace in a brute force way: I am retaining the rendered base circle of cone in each of the position of the aircraft. Next when the aircraft moves to next position, i again draw the new base circle, while i translate the cone i drew to show the searchlight.
DO u have any better way of doing this? ... Thank you!
