PSCAD电力系统高压直流输电的仿真与建模(PSCAD power system simulation and modeling of HVDC)

说明：  此程序使用LISP 变形语言scheme写的，分属于scheme的PLAI。 包括了parse方法，interp方法，有助于理解compiler的最基本思想。(This scheme uses the language written in LISP deformation, belonging scheme of the PLAI. Including the parse method, interp method to help understand the compiler' s basic ideas.)

在你选择的矩形中建立一个坐标网格，网格中含有坐标轴和面积

CAD常用命令集，希望对大家有帮助，这里包含了常用的所有命令，不用再去网上一个个搜索了。(CAD commonly used set of commands to want to help everyone, contains all commands used here, do not go online to a search)

Entities manipulation in autolisp

c#在不启动CAD情况下创建dwg文件,大家可以看下。

基于手绘线条的三维模型雕刻，一篇很不错的关于手绘建模的文章，c++代码实现效果(Based on the three-dimensional model of hand-painted line carving, an article very good about hand-painted modeling, based on the c++ code)

lisp学习应用 这个挺好的 建议大家学习一下 反编译也不错 就是没工具 那就下一个吧 还挺麻烦 随便上传一个小程序 呼伦一下吧(lisp CAD vba would did like a little piggie ?I like the fat pig,so I will buy a big fat pig and a little doggie .)
