The development of brake three-dimensional parts library based on CATIA

In the past, when need to draw one model of brake parts, users have to use the CAD software and make it one step by step, which wastes a lot of time and energy because of the repetitive artificially drawing. In order to improve the efficiency of drawing the models of brake parts, the paper builds one brake parts library by using the Visual C++6.0 and doing secondary development on the CATIA. Through one example, the paper proves the feasibility of building brake parts library.
