AutoCAD VB(VBA)二次开发在燃气管网水力计算中的应用

The application of AutoCAD redevelopment based on visual basic in gas pipe network hydraulic computation

本文利用VB(VBA)语言对AutoCAD进行二次开发,实现了对燃气管网节点、管段的捕捉及相关信息的读取,并利用VC++6.0对数据进行处理,实现管线节点的自动编号,自动生成管网的拓扑结构,然后调用燃气管网水力计算程序对管网进行水力计算,减小了燃气管网水力计算的工作量,提高了工作效率。

This paper uses Visual Basic （VBA） in AutoCAD nodes, getting the relevant information and using VC ＋ ＋ 6.0 redevelopment, realizing the Capture of gas pipeline network on the data procession to achieve the automation of numbering pipeline nodes and to generate Extended Network, then does gas network hydraulic calculation procedures for hydraulic pipe network. As a result, it reduces the calculation of gas pipe network and improves work efficiency.
