110KV变电站设计中所有的CAD图，里面有相关的进线保护、出线保护、短路电流电路图等(110KV substation design CAD drawings into line protection, outlet protection, short-circuit current circuit diagram)

一个离散的点坐标数据，通过CAD离散的数据处理技术，生成了合理点坐标数据。(A discrete point coordinate data, using CAD discrete data processing techniques, generates a reasonable coordinate data points.)

用于AUTO CAD里画的船体二维型线图上展开外板的插件(Expand the plug of the outer plate on the hull painting used for AUTO CAD 2D chart)

Entities manipulation in autolisp

AUTOLISP CAD批量将圆变成以圆心为坐标的点(Circular change point)

从多层树中取得偶数生成列，取得动态目标值的个数，从两个不同的树中，提取第二个树中独有的元素（和第一个树的元素不同的元素），并计算其和。(Generated columns to obtain an even number, the target value obtained from the dynamic multi-tree, from two different tree, extracts a second element that is unique in the tree (a tree of elements and different elements), and and calculate its.)

该程序实现了简单的画点，直线，圆，圆弧，水平或垂直线，长方形，多边形，表格，标注等，还有对画布的放大缩小等功能。菜单栏工具栏，功能齐全，是很好的vc开发cad的参考资料。

直接将坐标展在cad中和南方cass中的一功能相似，只是直接在cad中就直接能实现该功能。(Directly coordinate the event in cad and in the South cass of a function similar to, but directly in the cad on directly to achieve this feature.)

AutoCAD二次开发，visuallisp,用于矿业工程方向开发，地质建模，矿体建模，煤层建模！
