中文摘要：

导入到AutoCAD中的三维或二维等高线,存在手工标注高程工作量大、效率低、容易出错、不能有效利用高程信息等问题,针对这些问题,开发出在AutoCAD环境下能够实现等高线等间距自动标注的LISP程序,该程序具有通用性强、运行可靠的特点,其标注基本上能够满足人们的读图习惯,有效地提高了绘图工作的效率,对于解决AutoCAD环境下进行等高线手工标注的问题,具有一定的参考价值。

英文摘要：

The 3D or 2Dcontours after being imported into AutoCAD need to manually annotate the elevations,which has the problems as large workload,low efficiency easy to make mistakes,and inefficient use of the elevation information,etc.The paper developed the automatic equidistant dimensioning LISP program in AutoCAD environment.The program has the characteristics of versatility and reliablity, and the dimension could satisfy people＇s reading habits,which would help to effectively improve the efficiency of the drawings as a useful reference.
