基于VisualLISP语言快速提取CAD管线信息SWMM建模方法探索

摘要

通过AUTOCAD自带的VisualLISP语言对DWG格式的排水管网模型进行快速SWMM模型构建,并在某公园进行建模测试分析.结果表明:该方法易用且准确,可快速准确提取DWG管网数据中的管网数据(管径、标高、坐标等),对SWMM模型在中国的进一步推广应用有重要意义.%VisualLISP of AutoCAD was used to build a SWMM model rapidly for the drainage network model of DWG format,and this method was tested and analyzed by building a model for a park.The results showed that this method could rapidly and accurately extract the pipe network data (diameter,elevation,coordinates,etc.) in DWG,which was of great significance for the further application of SWMM model in China.
