【摘要】 本文提出了一个CAD枝术中的剖面线绘图软件的设计方法。说明了用直线多边形逼近复杂机械图形的工程可行性,以及在计算机处理速度上的优点。本文还提出了用模式识别方法代替传统的图形切割法来处理绘图跳步和空心复杂形体的剖面线作图,以解决绘图速度问题。更多还原

【Abstract】 This paper proposes a method of desiging the software for the section-line drafting in computer aided design and illustrates the engineering feasibility of drawing complicated mechanical figures with the shortest straight lines as well as the advantage of drafting speed.This paper also presents a method model distinction in place of the conventional method of cutting figures to solve problems of the leap of the drafng-pen in the process of drafting and the section-line drafting of complicated objects with an open space in the center.更多还原
