摘　　要：设计点、线、面综合作图题是画法几何教学中经常遇到的问题。提出了应用对偶性原理设计定位问题的方法,并通过实例证明了其可行性。Designing the comprehensive graphing exercises of the points,lines and planes is the problem that is oftenencountered in the teaching of the descriptive geometry., This paper puts forward the method for designing the problem ofthe positioning by using the principle of duality., and demonstrates its feasibility through some actual examples.

关 键 词：定位问题 对偶性 画法几何
