二维绘图中的自动消隐算法

Algorithm and Implementation for Automatic Hiding of 2D Drawing

该文以装配图为例，对二维绘图中的自动消隐问题提出并实现了一种有效算法。对该算法中的零件图边界构造、下层图素与零件图边界的交点计算、根据求得的交点对图素进行分割消隐等问题，文章进行了深入具体的讨论。

By using assemby drawing as an example, an effective algorithm is proposed and implemented for automatic hiding of an 2D drawing in this paper. According to the intersections,the paper discusses the construction of the boundary of a part-drawing (BPD) in detail, computation of the intersections of a drawing element to the BPD, and the problem to break up the element and to hide some sections of it properly.
