AutoCAD 图库联动在城市地下管线入库中的应用

城市地下管线随着城市规划、建设的发展而日益增多并处于不断的更新之中，对城市地下管线数据库的建设及更新是一项极大的挑战。深圳市自2005年来，每年对全市地下管线情况按片区进行调查及更新，多年的调查成果的累积使得数据入库处理工作量大而繁琐。通过AutoCAD图库联动功能的开发并将其应用在深圳市地下管线入库数据检查、数据接边及图形编绘中，实现了图库同步，简化了作业步骤，提高了作业效率，取得了较好的效果。

Application of Dynamic Relation Technology Between Graphics and Database Based on AutoCAD in Urban Underground Pipeline Data Inputting Database

Urban underground pipeline is constantly increasing and updated with the speeding up of urbanization .It is a great challenge for the construction and update of urban underground pipeline database .Since 2005 ,Bureau of Plan-ning,Land and Resources of Shenzhen Municipality has been surveying current situation of underground pipeline and up -dating the results database according to the divided area .Because of the long accumulation of pipeline data ,workload of data processing is large and complicated when inputting pipeline data to database .This paper discussed the common problems on the inputting database procedure in Shenzhen and gives the corresponding solutions which are realized by de -veloping AutoCAD function based on dynamic relation technology between graphics and database ..By applying of this technology from the aspects of data checking ,data edge processing and graphical compilation can realize the synchroniza-tion between drawing and database .It simplify the operation steps ,improve our working efficiency ,achieve good results .
