ObjectARX技术在三维地下管线建模的应用

三维地下管线通常在城市地下管线普查后,采用大型数据库支持建立地理信息系统,进行建模呈现。成果的一些管线交叉、管径异常等问题无法在普查过程中被及时发现处理。针对这些,本文介绍了一种基于ObjectARX技术的三维地下管线快速建模方法。应用本方法从管线数据库读取管点和管线数据,对地下管线普查数据进行三维建模,方便用户于AutoCAD环境中浏览、检查地下管线数据。

The Applications of 3D Underground Pipeline Modeling Based on ObjectARX

The 3 D underground pipelines usually after the census of the city underground pipelines, the use of large databases to support the establishment of geographic information systems, modeling presents. The outcome of the pipeline cross diameter abnormalities can not be identified in the census process handling. For these, this article describes the rapid modeling of an ObjectARX-based three-dimensional underground pipeline. Applying the method to read from the pipeline database management point and line data, three -dimensional modeling of the underground pipeline census data, and user-friendly browsing in the AutoCAD environment,check the under~round pipeline data.
