基于AutoCAD的地下管网图形属性一体化方案

摘要

描述了AutoCAD的数据库模型，在详细阐述DWG／DXF制图规范（ MSD）和AutoCAD属性数据存储方式的基础上，提出了通过严格按照MSD所定义的数据结构，对地下管网数据进行有效地存储与组织，来实现图形与属性的一体化。在此基础上开发了基于AutoCAD的地下管网系统，实现了数据编辑、数据查询、数据统计、辅助分析和数据质量检查等基本功能，同时，该系统所生产的地下管线数据可以轻松地实现面向ArcGIS的数据转换。%This paper describes the AutoCAD database model ,based on elaborate Mapping Specification for DWG/DXF ( MSD) and AutoCAD attribute data stored on the proposed MSD through strict accordance with the defined data structures ,underground pipe network data effective storage and organization ,to achieve the integration of graphics and at-tributes.On this basis,the development of the underground pipe network system based on AutoCAD ,to achieve a data editing,data query,statistics,assisted analysis and data quality checks and other basic functions ,while the system is pro-duced by underground pipeline data can be easily achieved for ArcGIS data conversion .
