： 针对目前工程实践中存在的 AutoCAD 制图数据到ArcGIS关系数据的交换和管理， 普遍存在着信息损失、 效率低下、

相对孤立、 数据无法双向流动、 难以更新等问题， 进行了深入分析和研究， 提出基于DwgDirect技术， 辅助ArcEngine实现Auto-

CAD数据到ArcGIS数据库的双向转换的方法， 很好的解决了上述疑难问题， 保证了CAD数据和GIS数据交换的高效性和严谨

性。在实际的空间数据相关工程实践中带来了巨大变化。对实现空间数据建库和管理的真正一体化， 本方法起着关键作用。-: Current engineering practice for AutoCAD drawing data exist in relation to the ArcGIS data exchange and management, the prevalence of information loss, low efficiency, relatively isolated, two-way flow of data is not difficult to update and other issues, in-depth analysis and research, presented Based DwgDirect technology, supporting implementation ArcEngine Auto-CAD data to ArcGIS database, two-way conversion method, a good solution to these difficult problems to ensure that the CAD data and GIS data exchange efficiency and rigor. In the actual practice of spatial data related projects has brought great changes. Building a database of spatial data integration and management of the real, this method plays a key role.
