Abstract

In a method for designing geometric shapes of products to be manufactured in a die molding process, which geometric shapes are described by means of multiangular basic figures, in particular triangles, in STL (structural triangulation language), by determining the draft angles of separate sides of these basic figures and determining the displacement vectors of the ends of the sides whose draft angles have been determined, a shape is given to the products allowing them, during their manufacture, to be readily removed from the relevant dies.
