Abstract: In combination with reform of mechanical curriculum provision in our college, the role of SolidWorks in machine design foundation curriculum system teaching was discussed, and the application mode of modular teaching case method, which is based on SolidWorks system, in theoretical teaching of mechanical principles and mechanical design, was proposed. And the teaching reform measures to integrate curriculum design of mechanical principle with curriculum design of mechanical design, based on SolidWorks system, were discussed. With the application of the engineering software SolidWorks system that was integrated with modern design idea and modern project concept, the theoretical teaching and practical teaching of machine design foundation curriculum system were organically combined, with the purpose of consolidating basic knowledge, developing the students' awareness and ability to use modern means to solve practical engineering problems, and improving modern teaching level and efficiency of our college.
