基于Civil 3D的排水管网辅助建模二次开发

Secondary Development of Aided Modeling for Drainage Network Based on Civil 3D

针对Civil 3D软件管网模块中缺失或者不完善的功能,进行二次开发,增加若干参数化建模功能,使其能够高效地进行市政道路排水管网BIM设计。基于Civil 3D.NET API,采用C#编程语言,开发了排水管网模型的参数化创建、批量修改、快速查找以及数据转换等功能;并在此基础上,探讨了Civil 3D管网模块二次开发的主要流程和若干技术细节。最后,通过实际工程案例,验证了二次开发功能对软件管网建模效率有显著提升。

Aiming at the missing or imperfect functions in Civil 3D software′s pipe network module,the secondary development was carried out and several parametric modeling functions was added,so that the design of the drainage pipe network of municipal road by Civil 3D could be more efficient.Based on Civil 3D.NET API,a series of functions were developed by using C#programming language,such as parametric creation,batch modification,fast search and data conversion of drainage pipe network model in Civil 3D.On this basis,the main process and some technical details of the secondary development of Civil 3D pipe network module are discussed.Finally,through actual engineering cases,it was verified that the efficiency of pipe network modeling by Civil 3D was obviously improved by the secondary development.
