Each group of the arbitrary figure attending operation has been expandded into a number of elements. Each element has been expanded into inside ring, outside ring, and virtual ring. The relative positions of elements between each group of figures are devoloped into the combinations of 4 cases, such as intersection, seperation, containment and coincidence 5 operations of union, intersection, difference, extension and containment can be made, then, 8 results can be obtained. Former modele adopting the broken line to approximate arc (curve) is fully changed, arc in here is used as a basic element to directly operate, and a series of problems of special attitudes which are given rise by arc have been solved. The problems of "queer coincide point"and"second queer coincide point", and "virtual ring" are put forward and solved. All work has Successfully realized to join with AutoCAD, therefore, it has the ability of interactive modification. The ready of practice has been gotten.

本文讨论由多个零件组成的两组任意平面图形进行并、交、差、外延和内含等5类运算的算法:各零件之间的相对位置关系,归结为相交、分离、内含和重合等4种状态的任意组合;而零件则由内环、外环和虚环等构成;将圆弧作为基本元素直接参加运算。提出并解决了“奇异重点”、“第二类奇异重点”和“虚环”等问题;整个工作成功地与Auto CAD进行了联接。

In this paper, we design a graphic data structure, which is suitable for describing common 2-D figure, detail drawings and assembly drawings. The concept of loop is used in this data structure. The algorithm of two loops (single loop) Boolean operation and the algorithm of the one-way bridge edge are presented. On the basis of the above algorithm, we achieve the algorithm of two graphs (many loops) Boolean operation. Also the special cases of Boolean operation are discussed.The graph algorithm provides a novel...

On the basis of the above algorithm, we achieve the algorithm of two graphs (many loops) Boolean operation. Also the special cases of Boolean operation are discussed.The graph algorithm provides a novel method for creating detail and assembly drawings, which must be expressed by many loops. The algorithm makes the processing easy, such as digging hole, merging in views , assembling among detail drawings.

本文设计了以环为基础的统一的图形数据结构,该数据结构覆盖了一般二维图形、零件图和装配图。在两个单环并、交、差图形运算的基础上,提出通过搭接单向桥边的方法,将单环算法直接向多外环、多内环拓展。文中详述了多环并、交、差算法,同时深入研究了图形运算中的奇异情况,取得了满意效果。 多环算法为零件图、装配图的生成提供了一种崭新的方法。因为零件图、装配图不可能用一般二维图形来表达,必然存在多外环、多内环,多环算法使我们可以直接在视图上进行打孔、拚接等操作,零件图拚装成为装配图的操作也极易实现。
