System Approach of CAD Experimental Courses for Mastering 3-Dimensional Design

Owing to the ubiquitous application of contemporary design and manufacturing technology,the contents of mechanical discipline have changed greatly.Moreover,in machine design and drafting,traditional teaching means and modes no longer meet the current demands.Ideas to reform the undergraduate courses of mechanical engineering majors are discussed,and a system containing three training courses for mastering three dimensional design technology is presented,namely "Engineering design tools","CAD and 3D design" and "Modeling with 3D CAD software".Following the curricula,students can have the concepts of design and get good training for making innovative engineering design.
