Geometrical substantiation of the graphical technique of building surface contours in perspective view

Abstract

The article presents the original method of geometric construction of axonometric essays of spatial forms. The imposition of the horizontal projections of these forms with the horizontal projections of their axonometric outline. is used, which makes it possible to find reference points by orthogonal drawing. The relationship between the axonometric outline of the object’s surface and the corresponding contour of the same surface on the projection drawing is established.
