Spatial Configuration Ability Training in Engineering Graphics Course Using CAD Software

Abstract

A new engineering graphics course teaching mode which aims for training spatial configuration ability using 3-D CAD software is presented in this paper. Through this teaching mode, the student’s spatial orientation and spatial visualization are enhanced and extended, and the ability for innovative design can be cultivated. The training for spatial configuration ability consists of three main methods: basic solid body design, extension model design and special topic design. The basic solid body design can help the students to understand various basic geometric elements and their positions directly on a virtual solid body. The extension model design is useful for divergent thinking training. The special topic design is helpful for creative and innovative thinking. After training for a semester in engineering graphics course, the spatial configuration ability for mechanical engineering student is enhanced obviously, and this ability make them more creative for subsequent professional curriculum and actual production manufacture.
