A Computer Aided Method on Descriptive Geometry

Along with the spreading of computer graphics in teaching and engineering,there are two opinions about dealing with descriptive geometry.One thing is the principle kernel of descriptive geometry should be inherited,to adapt for the request that 2D and 3D may be existing together for a longtime.Another thing is,computer technology should be used at first time in training of engineering drawing,to enhance visibility,precision,efficiency and to fit into courses following.The Computer Aided Method on Descriptive Geometry can integrate the advantages of the two above,provides new technology in teaching descriptive geometry and drawing training.
