Conference paper


With the advent of CADD, especially 3-D CADD, in industry and in educational institutions it has become imperative that educators take a close look at the subject of descriptive geometry, the method of orthographic projection, and their accompanying instructional methodology. This paper investigates the history and uses of descriptive geometry and orthographic projection in industry and in traditional engineering school curriculum. How these topics are being influenced and altered by the addition of CADD systems to engineering graphics classes is the main theme of this paper.
