CAD

基于PSCAD/EMTDC搭建的双向dcdc，可做参考(Bidirectional dcdc based on PSCAD/EMTDC，provide you a strategy to build DCDC)

cad中可以像cass一样划线,具有换向，隔点闭合等功能！(cad cass huaxian)

说明：  一个Visual Graph开发程序，具有类似MS viso的功能！带有C++,Delphi,VB,C#等的代码示例！(a Visual Graph development programs that have similar functions VISO MS! With C, Delphi, VB, C# code examples!)

可将.txt数据转化为grd数据，用于grads画站点图(.txt data can be converted to GRD data for grads drawing site map.)

自动绘制保护煤柱,CAD 二次开发的，输入参数后，自己就绘制出来了(Automatic drawing protection pillar, CAD secondary development)

说明：  点阵式液晶图形显示模块画图功能的实现 西北工业大学 赵伟杰 范蟠果 (dot-matrix liquid crystal display modules drawing Realization of the Northwest Industrial University Zhao Wei Fan Panguo)

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.)

用vc+mapobjects开发的源代码，实现鼠标多边形的移动(with vc MapObjects development of the source code, mouse polygon mobile)

说明：  实现中点画圆 在qt平台上实现 语言为c++ 是计算机图形课上的代码 可以编译通过的(realize draw the point in the middle)

几个经典用C#画图的例子，包括正弦和曲线图形，很实用的，在VS2008下运行过(Several classic examples of C# drawing, including sine and curve graphics, very practical, run under the VS2008)
