摘　　要：组合体内容是制图课程学习的重点和难点。为提高学生对组合体知识的掌握能力,通过连续安排三次实物模型徒手绘制其三视图的练习,按照由易到难,由简单到复杂,力求使学生每一次的实践练习都有较强的针对性和收获。实践表明,该实物模型绘制的三步法实践,取得了很好的教学效果,得到了学生的广泛认可。The content on assembly is the key point and difficult point in the drawing course. In order to improve the master ability of assembly knowledge, through three entity model drawings are arranged to draw their three-dimensional picture after learning the theory method of drawing assembly. Following the demand from easy to difficult, from simple to complex,each exercise has exercise has strong pertinence and makes the students learn something. The practice shows that, the three-step practice of mapping entity drawing obtains good teaching results and get the wide approve from students.
