Abstract
In a mechanical CAD/CAM system the 3D geometric structure of parts have to be specified. There are two classes of methods for specifying the geometry of the parts, i.e., 2D-oriented and 3D-oriented. In the first class we examine the methods of representing the mechanical part by an engineering drawing with the top, front, and side views in orthographic projection. We shall propose a system which automatically interprets the engineering drawing by employing image processing techniques and derives the 3D geometry of the part from the 2D views.
Next, the class of 3D-oriented methods for part geometric modeling if reviewed. In this class we shall provide a system to facilitate the user to creat and edit a 3D part, with the aid of both wire frame and shaded displays.
