A new scheme for constructing training resources of design graphics

A new scheme for training answers preparing and its teaching on design graphics is presented. In this method the answers are prepared firstly from 3D design, then these 3D models will be converted to 2D engineering graphics. 2D graphics will be further modified by 2D graphing software and the final answer will then be obtained. In which method the 2D answers and their 3D models could be obtained at the same time and will both be shown for help trainees understanding. The teaching efficiency is improved by proposed scheme.
