AutoCAD二次开发在工程计算软件中的应用

摘要

Drawing with AutoCAD has become an integral part of engineering design. It is emphasis on the discussion of methods of secondary development of AutoCAD with ActiveX technology based on the detailed analysis of several methods of secondary development of AutoCAD. Some essential methods are introduced such as method of connection with AutoCAD using VC#, drawing basic figures and operating layers and so on. It is applied in calculation software development of pier by computer aided design, and implement the parameterization and rapid design of wharf design in VC# visual design environment, reducing manual intervention and the probability of error.%AutoCAD画图已经成为工程设计必不可少的一部分.在对几种AutoCAD二次开发工具进行了详细的分析基础上,重点探讨了如何使用ActiveX技术对AutoCAD进行二次开发的方法.介绍了用VC#连接AutoCAD的方法、绘制基本图形和操作图层等具体技术手段,并把这些技术应用到重力式码头CAD辅助设计计算软件开发中,利用VC#可视化编程设计实现码头工程的参数化和快速化设计、减少人工干预和降低出错概率.
