摘要： 通过分析三维管网可视化模型的实现方式，构建三维管网空间数据模型，选用Flt三维数据图形格式，提出了基于工程测绘数据、纸质蓝图和DXF格式CAD文件三种形式的三维管网模型自动构建技术；基于Vega Prime的场景漫游开发，可将地上建筑、地下岩层、管网等其它Flt模型引入到系统中，共同驱动，实现大场景城市地下管网的快速建模与三维可视化漫游。

Abstract: Through analysing the way to realize the 3D pipe visualization model, constructing its digital model, and adopting Flt document, the paper proposes the automatic construction technology of 3D pipe model based on the survey data, blueprint and CAD document format DXF. On the basis of Vega Prime, such Flt models as buildings, underground rock layers and pipes can be introduced to the system and can be driven jointly. Through the above-mentioned technologies, fast modeling of urban underground pipes and 3D visualizational browzing are realized.
