Sorry for my english. I have a geometrical problem. I need to dessing a label for a packaging, and i need to create the planar siluete of a label for a container. The top of packaging is a ellipse and the botton is a circle. If i know two diameters of the ellipse of top, the diameter of the base, and the alture of the packaging, how i can calculate the siluete of the labal in planar view.
