传统的二维投影图已经不能满足时代发展的需求,随着CAD/CAM技术的日益普及,三维CAD技术已经贯穿于整个机械工程设计及制造的过程当中,本文根据工程图学与三维CAD技术之间的关系,以三维设计为核心,结合手工绘图与计算机绘图,对工程制图课程的教学内容和教学形式的改革进行了阐述。
Traditional two-dimensional projection images can not meet the needs of the development of the times. With the increasing popularity of CAD / CAM technology, three-dimensional CAD technology has been throughout the mechanical engineering design and manufacturing process, according to engineering drawings and 3D CAD technology The relationship between the three-dimensional design as the core, combined with manual drawing and computer graphics, engineering drawing course teaching content and teaching reform are described.
