摘要
提出一种借用ＡｕｔｏＣＡＤ的三维功能解决二维图形消隐问题的方法，并对其中的几个关键技术问题进行了详细的讨论，解决了任意复杂装配图的生成问题。该方法通过直接调用ＡｕｔｏＣＡＤ内部命令ｂｏｕｎｄａｒｙ 和ｓｕｂｔｒａｃｔ完成平面图形内外轮廓的搜索，然后将互相覆盖的图形设为不同的深度值，直接调用Ｈｉｄｅ 命令对二维图形进行覆盖消隐。实例运行表明该方法效率高。
A new approach of removing hidden edges for 2 D drawing by using the 3 D function of AutoCAD is proposed, and several key problems of designing assembly drawing are discussed. According to this approach, contour recognition is completed by using AutoCAD's BOUNDARY command and SUBTRACT command, different 2 D drawing is set different Z coordinate value, and then the problem of removing the hidden edges is completed by using the AutoCAD's function of 3 D.
