| 摘 要： | 以 AutoCAD 2000 为绘图支撑软件,采用其最新开发工具 ObjectARX 2000和 Visual C 6.0 编译环境,在分析分幅地形图 DWG 文件之间关系的基础上,对其图形数据库进行操作,实现了图形拼接。根据公路、铁路选线设计中裁图、折图的要求,以线路中心线为依据确定裁图边界并获取其相应数据,实现快速裁图、擦图及折图。用本技术开发的选线设计系统可用于公路、铁路选线设计,并已在青藏铁路选线设计中得到应用。

| Abstract: | Taking AutoCAD 2000 as a Supporting Software of drawing and by employing newly-developed tool ObjectARX 2000 of AutoCAD2000 and language surroundings of visual C 6.0, baseing on the analysis of the relationship among the DWG files of the separate topographic maps, and working on their database, the uniting of the maps can be realized. By setting trimming edge according to route center line based on requirement of the high way and railway route-choosing design, the quick trimming, rubbing and folding can be realized. The system of the route-choosing design developed through the technique has been applied in the Qing-Zang railway route-choosing design. |
