用Csharp做的AutoCAD的二次开发，实现dwg文件的读取显示，保存(Csharp do secondary development of AutoCAD, the dwg file read, save)

这是国外的同行编写的画图板程序，感觉比陈建春的要好些，说实话研究了半天，发现国内的cad水平低不是因为国内的人笨，主要是国外的cad技术不能很快的传递到国人手中，总是参考陈建华等水平有限，工程水平差的书籍造成整体水平低，书中没有详细的流程图，和软件设计思路，而且代码错误连篇。(This is the foreign counterparts of the drawing board to prepare procedures, CHEN Jian-chun than feeling the need to better tell the truth for a long time study and found that low levels of domestic cad because people are not stupid, mainly abroad cad technology should not quickly delivered to the the hands of the people always refer to Chen Jianhua, such as the limited level, engineering level difference caused by the overall level of books low, the lack of a detailed flow chart of the book, and software design, and code errors pack.)

本包含两个程序，一个是实现二维数据（X,Y）实现画一个圆的功能。另一个是实现20万数据作为雷达强度反应到圆上。本案例是画雷达图的(This contains two procedures, one is a function achieve two-dimensional data (X, Y) to draw a circle. Another is the reaction to the data of 200,000 as radar intensity circle. This case is painted radar chart)
