ObjectARX自定义实体的地下管线前端数据采集系统开发

Design of underground pipeline front-facing data acquisition system on the basis of custom entity of ObjectARX

采用ObjectARX的自定义实体开发技术,可以创建在AutoCAD中没有的自定义管线实体,该实体集成管线的属性数据和几何模型,随管线属性数据不同而自动改变符号、注记和其他图形表现,完成管线属性数据与几何图形的深度结合,再利用AutoCAD风格的MFC界面开发技术和数据库技术,实现管线数据采集系统在Auto-CAD的高级开发。

The paper studied on creating pipeline entity via ObjectARX in AutoCAD.Custom pipeline entity,combining both property data and geometry models,can alter automatically signs,labels and other graphic display when property data change.It integrates property data with geometry display on profound level.The advanced development of pipeline data acquisition system can be implemented by using MFC of AutoCAD style and technology of database.
