当前测绘行业很多都是基于DWG地形图数据的数据库建设，生产中一个关键的环节就是DWG到SHP格式的无损转换，尤其是属性的转换。目前，没有现成的软件能一步到位地实现转换，通过对DWG和SHP格式数据结构的研究，采用VC＋＋2005和ObjectARX SDK开发环境，在AutoCAD平台上二次开发，图形数据按点、线、面转换，属性数据分扩展数据、扩展记录、对象数据、对象特性转换，完成了DWG到SHP的格式转换，同时满足图形和属性的要求，操作简单快捷，在实际生产中取得较好的应用效果。

The current surveying and mapping industry is based on topographic map database establishment with the key step of DWG to SHP format lossless conversion , especially property conversion .There is no readily available software which can realize one step conversion.Through the DWG and SHP format data structure , using VC++2005 and ObjectARX SDK development environment , secondary development on AutoCAD platform , graphics data conversion in terms of the point , line and polygon, attribute data, XData XRecord, OData, OProperty conversion , DWG to SHP format conversion is achieved , and requirements of graphics and attributes are satisfied with simple and quick operation and good application in the actual production .
