| 摘 要： | 针对当前市场上很多地形图成图软件在分幅时裁剪不干净,容易丢对象和分幅速度慢等情况,笔者使用Vi?sual Lisp编程语言,基于Autocad中的“Break”命令开发了一个相对完善的裁剪工具以代之.

| Abstract: | Currently, many topographic map-generation soRwares cannot produce a clean subset image, easily lose objects and are slow in formation of a subset image. Instead, this paper, based on the command ＂break＂ of Autocad, developed a relatively perfect subset image tool using programming language VisualLisp. |
