微机重力坝CAD系统运行方式和数据、图形处理技术

Operation, Data and Graph Processing of CAD System for Gravity Dams

对微机重力坝ＣＡＤ系统进入或脱离下拉式菜单的两种运行方式作了介绍，指出运行时的注意事项。并就系统的数据、图形处理技术作了说明，介绍了库文件及地形、地质数据的生成过程，以及进入ＡｕｔｏＣＡＤ绘图的两种方式。

The CAD system for gravity dams can be operated under pull down menu and non-pull down menu operations. This paper points out matters needing attention, explains data and graph processing techniques,briefs database files and the creation processes of topographic and geological data, and introduces two methods of entering Auto CAD.
