浅谈在MicroStation中编制地形图符号

MicroStation是一套可执行于多种软硬体平台的通用电脑辅助绘图及设计（CAD）软件。在MicroStation中，其制作的符号被保存在一个后缀为CEL符号库文件里，使用时只需正确连接符号库即可。使用MicroStation绘图时，SHARECELL功能为图形符号的替换带来方便。地形图主要使用GRAPHIC、POINTS两种符号类型，其可以通过层、颜色等属性来定义。符号制作时可依据国家标准地形图图示，设置大小及符号原点。设置合适的比例，库中符号则可绘制不同比例尺地形图。MicroStation的符号制作功能虽然灵活，但没有提供对符号要素的编辑功能是软件的一大缺陷。

Topographic Map Symbols Compilation through MicroStation

The MicroStation is a set of all-purpose computer aided drawing and design （CAD） software and can be performed on multiple software and hardware platforms. In MicroStation, the symbols it made are saved in a file with an extension .eel, only if to connect symbol library correctly then they can be used. When drawing through the use of MicroStation, the function ＂SHARE CELL＂ can bring convenience to graphic symbol displacement. Two symbol types of ＂GRAPHIC＂ and ＂POINTS＂ are mainly used in topographic maps and may be defined through properties of layers and colors. The making of symbols can comply with topographic map diagrammatic representation national standard to set sizes and base points. Through appropriate proportion setting, symbols in the library also can be used in different scale topographic map drawing. Although the symbol making function is flexible, but without symbol constituent compiling function is a major shortcoming of the software.
