摘　　要：在基于CAD的地下综合管线图中,管线点应进行统一编号并应保持其同一测区内的唯一性,通过对规程、规范中管线点编号规则及Visual Studio.NET 2022中VB语言二次开发AutoCAD的相关技术研究,编程实现了测区内管线点编号以标准图幅为单位分类重新排号的过程方法,提高了管线信息系统建设的效率和规范性,所研究开发的代码和函数,为广大城市管线信息系统从业者开辟了一条新的工作思路。In a CAD-based integrated underground utility network diagram,pipeline points should be uniformly numbered and their uniqueness within the same measurement area should be maintained.This is achieved through the numbering rules of pipeline points in regulations and specifications,as well as Visual Studio.NET 2022,the related technical research on the secondary development of AutoCAD using VB language in which has been carried out,and the programming method has been implemented to classify and rearrange the pipeline point numbers in the survey area based on standard map units,improving the efficiency and standardization of pipeline information system construction.The code and function developed in this study have opened up a new working idea for urban pipeline information system practitioners.
