摘　　要：本文利用参数化设计思想和约束的基本理论,结合参数化绘图为平面图形提出了一种新的尺寸标注方法,该方法能够自行消除尺寸的冗余和不足,保证了尺寸标注的完整性和标注过程的确定性,为设计者标注尺寸提供了理论依据。This paper put forward a new method of dimension label in plane graphics by using the design idea based on parameter and the basic theory of restraint and combining with the drawing based on parameter. The method can eliminate the redundancy and shortage of dimension by itself. So it ensures the integrality of dimension and the definition of labeling process, and provides with theoretic reference for designers in dimension
