基于ObjectARX的线划图文件批量处理研究

数字线划图(DLG)是我国基础地理信息数字成果之一,外业测绘的成果一般就是DLG。DLG使用较为广泛的格式为AutoCAD的DWG格式,阐述了DWG格式的线划图文件批量处理。图形文件批量处理就是根据用户的需求对多个图形文件进行相同的操作,这些操作可由计算机自动化完成。ObjectARX是AutoCAD常用的开发工具,研究了基于ObjectARX与C#.NET对AutoCAD进行二次开发,实现线划图文件批量处理的技术,具有较好的现实意义与广泛的应用前景。

Study on Batch Processing for Digital Line Graph Files Based on ObjectARX

Digital line graph （DLG） is one of the digital products of fundamental geographical information in China, in general, surveying and mapping achievement is digital line graph. The more wideused format of DLG is DWG format in AutoCAD. This paper described batch processing for line topographic map files on the DWG format. Batch processing for graphics files refers to same operation on a plurality of graphics files on the user＇s behalf, which can be done automatically by computer. The common development tool of AutoCAD is ObjectARX. The secondary development of AutoCAD based on ObjectARX and C#. NET has been investigated in this paper. The technology of batch processing for line topographic map files has been realized. It has practical significance and extensive application prospects.
