Abstract:

Models are indispensable teaching aids in mechanical drawing courses. Virtual models can be easily created, and object ones have stronger sense of reality, so they are both used very widely. Unfortunately, students are passive to use these readily-made models. It is better to lead students to make object models. Therefore, it is very important to set up a platform that can create various object models easily. Such a platform based on rapid prototyping theory is produced in this paper. Various models can be made with a computer and a printer. The process of making models not only effectively stimulates students to learn, but also helps students to understand such difficult content as truncation, auxiliary plane method and cutting.

Key words: engineering graphics, mechanical drawing, rapid prototyping, model
