<p>Procedure for obtaining series of conjugate ellipses, suitable for producing orthogonal axonometric representations, characterized by the fact that it meets the adoption of new criteria for the production of ellipse templates. It consists of the assignment of a serial number, preferably between 4 and 36, that distinguishes the ellipses intended for Axonometric Perspectives of those in Axonometric Drawings, and a code number, preferably between 1 and 36, that identifies them by types, since it is proportional to the square of the sine of the angle of projection corresponding to the circle that gives rise to them. This configuration facilitates the choice of the serial ellipses forming part of the axonometric representations, by means of the formation of short lists of codes, with or without repeating them, on condition that their sum is equal to the serial number, and enables, based only on this data, the determination of: The angles of projection, the relation between the axes of the ellipses, the axonographic angles and the reductions applicable to the axonographic directions.</p> |
