| Abstract: | In this paper, the authors have presented two calculational methods for the development of the three-dimensional surface-triangular mesh development and restrict weight development. The two methods are based on the rule of the geometrical mapping and the invariable area, applied to the multi-point forming. At last, the authors programmed the software. It has been applied to the saddle specimens the and high-speed train parts. |
