Design and drawing is a core courses in mechanical engineering. Fourth grade student designs a two-stage gear reducer for 1 year. Performing design calculations using C language. It's modeled by 3D-CAD and the safety factor is confirmed using a CAE analysis. Then shaped it using three-dimensional printers. Finally the students have a presentation using the PowerPoint and video for each group. In this paper, based on the curriculum of courses that they are exercises, we will introduce our efforts in the lecture.
