基于二维和三维CAD平台的机械制图课程改革探索

摘要

随着计算机技术的日益普及，为了适应现代设计制造技术的要求，对机械制图课程进行改革势在必行，即在机械制图、AutoCAD课程的基础上再增加计算机三维绘图，形成新的机械制图教学体系。这种教学体系，促进了学生计算机绘图能力的提高，激发了学生的学习兴趣，培养了学生的空间思维能力和创新能力，使传统的机械制图课程显示出极大的活力。%With the growing popularity of computer technology, in order to meet the requirements of modern design and manufacturing technology, mechanical drawing course has been reformed: the three - dimensional computer graphics is added to courses of mechanical drawing and AutoCAD to form a new teaching system of mechanical drawing. This teaching system, improved students' computer graphics capabilities, stimulated students interest in learning, cultivated the students'spatial thinking and innovative ability, and showed great vitality of the traditional mechanical drawing course.
