转换适普ext格式等值线到cad 转换适普旧版dem格式 基于aotucad-vba开发

根据导入得dem（固定路径），生成等值线图（2维），是地形图绘制，DTM三维可视化较好的例子，但要转三维还要继续努力！-According to import must dem (a fixed path), generate the contours (2-D) is the topographic mapping, DTM three-dimensional visualization of a better example, but to change to 3D must continu

可实现规则化DEM文件选择读取与现实、设置等高线间距、实时位置查询、高程亮度显示、等高线自动绘制。包含一个实例文件-DEM file read and display, select contour interval, real-time location query, height display brightness, automatic contour drawing height. Contains a sample files
