用section图切剖面方法辅绘工程地质剖面图

工程地质剖面图可以通过计算机与少量手工绘制能够清楚的反映地下地质体的地质信息,包括岩性、构造的空间分布状况。通过对地质体的剖面信息的绘出,可以使我们更加清晰的了解地质体的时空、空间分布的三维立体情况。本文通借鉴前人图件计算机辅绘原理与方法。利用section新方法画出的剖面信息,改变后应用于符合生产要求的工程地质剖面图,是工程顺利开展的先决条件。该方法简单高效,可以满足不同比例尺的要求。

Detecting Adjacent Relativity of Engineering Drawing Entities with Container Window

Automatic recognition and interpretation of engineering drawing plays an important role in computer aided engineering. Detecting the positional relation between entities is an important topic in this research field. In this paper the concepts of adjacent relativity and container window of drawing entities were proposed. By means of container window, the adjacent irrelative entities can be detected quickly and effectively, which speeds up the process of adjacent relativity detection. Meanwhile, the algorithm of adjacent relativity detection was discussed.
