Determining the Coordinates of the Points on the Contours of the Development of Quadratic Surfaces and Their Intersections

The article presents a method for determining the coordinates of points on the contour of the development of quadratic surfaces and intersections on quadratic surfaces based on the method of analysis, graphic geometry combined with computational programming. The calculation results are programmed in the Autolisp language to determine the coordinates of points on the intersection, thereby constructing the development of quadratic surfaces and their intersections, applied in mechanic and teaching.
