| Abstract: | By means of front projections, after analysing the projective features of the section ellipses in cylinders and cones,this article puts forward a method of seeking answers with the aid of section ellipses, which solves some intersection seeking problems in some non -revolutionary surfaces in a easier way and provides a new drawing method for measuring and locating problems in plate technology. |
