摘　　要： 工程设计现在已发展到全数字阶段,能使设计、制造一体化过程得以实现的核心是三维实体模型,二维投影图已满足不了形势发展的需求。因此,基于三维CAD绘图技术,我院开展了机械制图课程“3D实体教学法”的教学改革,其思路一是直接从3D实体图形开始学习,而不是传统的从投影概念、2D投影视图开始学习,二是以3D实体造型而不是传统的以画法几何作为教学的基本核心。在此基础上,提出了一种以“使学生成为自主学习者”为目标,突出“三维”和“设计”新思想,在习题配置这一环节上所进行的配套措施,以此来深化教学改革。 Modern engineering design has entered the digital time. The kernel of realizing the integration of design and manufacture is the 3-demension geometric models of the products, which the 2-demension drawing cannot help. Therefore, the course reform of 3D solid teaching for mechanical drawing based on 3D CAD is brought about, claiming that the teaching sequence should proceed directly from 3D solid drawing instead of from the concept of projection and 2D projection drawing, and should emphasize 3D solid drawing instead of descriptive geometry. As a result, the reform of exercise arrangement for mechanical drawing course is proposed, which can make active learners out of students. By the use of this from out teaching innovaton can be deepened.
