【Abstract】 With the development of computer technology and the popularity of the 3\|dimension(3D) design software, engineering design has developed from 2\|dimension(2D) design towards 3D. It would be a tendency in the reform of the system of engineering graphics teaching to introduce the method and idea of 3Ddesigning and cultivate the ability of students to design and express via 3D design technique in the need of engineering design.更多还原
