制作水工模型时人工读取地形断面数据费时费力，提出了用Visual basic6.0开发绘制地形断面的自动化系统的方法，介绍了程序的原理、功能以及实现方法与特点，并用工程实例说明了程序的使用过程和结果。实例应用结果表明本系统能提高制作效率、避免读数错误，且满足精度要求。

Troublesome problems in getting the data of topographic sections were indicated before a hydraulic model was made. Based on Visual basic6.0, an automatic system for drawing topographic section in hydraulic model was proposed. The principle, function, method, and characteristics of this system were introduced. The process and its result were illustrated with an example.The results showed that the system can enhance manufacturing efficiency, avoid
man － made reading errors and meet precision requirements. 
