AutoCAD环境下地形图面状充填符号的产生

Making of area filling symbol of topographic map in AutoCAD

本文利用AutoCAD软件丰富的二次开发功能,通过对CAD阴影充填基本方法的讨论,实现了在大比例尺地形图中按图示制图符号自动绘制面状地物充填符号。这一方法对于利用AutoCAD编辑、绘制、管理地形图,提高地形图的绘制精度,具有较大的价值。

By discussing of the basic mothod of CAD shadow filling, it is realized that drawing area filling symbol of object automatically by topographic map symbols in large scale topographic map with the rich second exploiting functions of AutoCAD. This method has higher value for the editting,drawing and management of topographic map,and for improving drawing precision of topographic map.
