可以进行空间曲面的拟合 用于曲面拟合的代码：圆 球 直线 平面拟合都有(Surface fitting code: round ball linear plane fitting)

用VS2012和open cv2.47编写的一个简单画图板程序，可以像画图板一样用鼠标画任意图形(Using VS2012 and open cv2.47 drawing board to write a simple program, you can use the mouse as the drawing board, like any graphic painting)

在AutoCAD中添加一个自定义分页侧边栏。(In AutoCAD add a custom tab sidebar.)

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.)

极其简单的MFC画图小例子，但是可以学到很多的基本知识，不错的例子，微软出品！！！！(Extremely simple MFC drawing small example, but you can learn a lot of basic knowledge, a good example, Microsoft Publisher! ! ! !)
