在CAD电子地图中根据路径多段线剖 纵断面图。-In CAD of electronic map in accordance with the path of multi-segment line Sectional Drawing of the autopsy.

利用VB进行cad二次开发得到线路勘测设计系统，可进行线路的平纵横断面数据管理。-VB to cad secondary development line survey and design systems, and line level vertical and horizontal cross-section data management.

VBA开发了CAD宏，可以批量提取CAD文件中多段线长度到文本文档，稍作修改可以用于河道断面、中心线等提取。-get cad lwpolylines lenth

在CAD平台下运行，能根据原始测量数据，自动绘制原始横断面图。适用于工程测量及设计人员。(Running on the CAD platform, the original cross section can be automatically drawn according to the original measurement data. It is suitable for engineering survey and design personnel.)
