地形图点状符号遮挡地物自动删除的程序开发

摘要

Point in the topographic map of AutoCAD exists in the form of block of graph. According to the features of thematic topographic maps used in different fields and part of the point symbols can be deleted, develop this program by using VBA, the second time developing tool of AutoCAD. Program will delete those point symbols covering culture. realized topographic map automation dressed, thus make the topographic map focused to highlight, distinct level, and improved the aesthetics of the drawings and the efficiency of operational greatly.%在基于AutoCAD的地形图中,点状符号多以图块的形式存在于图形空间中,依据专题地形图使用的领域各不相同及部分点状符号可以删除的特点,使用AutoCAD集成的二次开发工具VBA编写程序可将遮挡地物的点状符号进行自动删除,实现地形图自动化整饰,从而使地形图突出重点,层次清晰,提高了图面的美观性和作业效率。
