A Computer Aided Method of Descriptive Geometry

Along with the spreading of computer graphics in teaching and engineering, there are two opinions about how to deal with descriptive geometry. One is that the useful kernel of descriptive geometry should be inherited and adapted for the request that 2D and 3D may exist together for a long time. The other is that computer technology should be used at the first time in the training of engineering drawing to enhance visibility, precision efficiency and fit into follow-up courses. The Computer Aided Method on Descriptive Geometry can combine the two advantages mentioned above, provide new technology in teaching descriptive geometry and drawing training.
