【摘要】 铁塔ＣＡＤ系统是已经研制成功的一种用于自立式输电铁塔设计分析的工程ＣＡＤ系统。它主要包括前处理、分析优化和后处理三个子系统。它的研制充分采用了当前先进的面向对象技术、可视化技术、数据库技术和合齿法优化技术，具有技术先进、使用方便、易于推广等优点。文章简要介绍了铁塔ＣＡＤ系统的构成、实现思想以及实现技术，从而为其它工程ＣＡＤ系统的开发提供有益的参考。更多还原

【Abstract】 Steel power-tower CAD-TowCAD is a highly integrated engineering CAD system for analyzing and designing steel towers. It is composed of 3 subsystems:the pre-processing one,the analysis and optimization one and the post-processing one. It is developed adopting the current advanced development technologies such as object-oriented technology, visualization, database technology and optimization method. Some outstanding advantages have been achieved in the system. In this paper,the ways and the technologies for realizing TowCAD have been discussed in brief,which may provide good ideas for developing other engineering CAD systems.更多还原
