4 . on original data arrangement of views , first , this paper discusses the instance of line overlap and gives the concept of hidden point , next , a method for breaking line is put forward by the means of handling two lines intersection , at the end , data check and correction is described through topological relationship between primitives and dimension set of drawing . to make a summary , from the viewpoint of practicality , the method of engineering drawing pre - processing proposed in this paper over comes traditional 4 .在视图原始数据整理方面,首先讨论了重叠边的分解与重构方法;然后给出了隐含点的概念,通过对二维线段相交情况的处理分析了求取隐含点的断线算法;最后描述了如何利用实体的拓扑关系检查输入视图中的错误以及利用工程图中的尺寸集来校正这些错误。
