# DrawRoadProfile

通过读取路面桩号的Excel表自动绘制纵剖面图程序(含相应AotuCad图及Excel数据）

这个程序是用于一个乡村道路绘制竣工图时使用的，主要作用是用来画该公路工程道路的纵剖面图。

由于道路剖面图在竣工图绘制中由于是绘制测绘值，数据量极大，公路工程纵剖面图节点非常多，如果照着数据一个一个手工输入绘制，速度慢而且极易出错，可能要用三天时间，如果遇到数据修改，工作量更大。现采用AutoLisp设计程序对原测绘数据形成的Excel表进行自动读取并根据要求绘制，这个程序并调试用了一天，完成后仅用了10分钟即完成图纸绘制。后来的数据调整也用的这个程序，方便快捷。
