Using full scale templates for drawing saddle shape curves is a traditional method. This method is very troublesome and complicated. But under the aid of computer program for calculating coordinates on saddle shape curves, the tedious work of drawing lofting becomes labour-saving owing to more simple, accurate and timesaving than the traditional method. This paper depicts the geometric model establishment of coordinate lofting of saddle shape curves and its contents and characteristics, as well as the application method of the program system. Engineering practice shows that this program system is of better utility and economic value.
