With research direction refinement and information globalization, knowledge economy puts forward higher requirements to high-level talents. University education is very important to cultivate high-level talents. For students of mechanical-related majors, the cultivation of college students’ comprehensive application ability has become an important problem to be solved urgently. In view of current CAD comprehensive training of college students, environment for engineering reality is provided difficultly. This paper sets the development of “Standard Parts Library of Rolling Bear Based on SolidWorks” as an example to illustrate that mechanical engineering students make teamwork and collaboration to complete the standard library research and development and cultivate their CAD comprehensive ability in research project. Through the application of practice, we find that the proposed training method can not only be applied to senior students, but also to lower grade college students, and it also creates a new educational model in cooperative environment.
