观察Autocad内部数据组织的最佳工具,这个对应Autocad2(observation Autocad internal data organization the best tools, and corresponding Autocad2)

可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

说明：  计算机图形学实验，完成立方体的三视图和等轴侧投影(Computer graphics experiments, the completion of three cube view and isometric projection)

off 转stl ，很好的转换软件源码。实现了off三维格式向stl三维格式转换，可用于CAD、ProE等软件对接。( Turn off to stl, good conversion software source code. Off to achieve a three-dimensional format stl three-dimensional format conversion, it can be used in CAD, ProE and other software docking.)

关于三轴雕刻机用C语言实现，此为C方式下实现绘画CAD图。(About three-axis engraving machine with C language, this is C mode drawing CAD drawings.)

PSCAD仿真,可以设置各种故障,故障类型可以自由设置,并且得到故障仿真图形,本程序中附有单相故障(PSCAD simulation, you can set a variety of failures, fault types can be set free, and get fault simulation graphics, the program with a single-phase failur)

用MFC实现画图板，包括绘线，几何图形，上色等等，简单易懂。(To realize drawing board with MFC)

简单的图形学SRGP教学包运用实现。 A．实现一个下拉菜单软件包，其高层设计见2.2.6节、2.3.1节、2.3.3节中的代码段。软件包通过从输入文件读入字符串来初始化菜单条和菜单体。程序可以通过关闭菜单条使标题消失，也可以激活一个菜单（以各菜单标题在菜单条上的水平位置作为参数）来使菜单出现。 (Simple graphics SRGP realize the use of teaching packages. A. The realization of a drop-down menu package, and its high-level design, see section 2.2.6, section 2.3.1, section 2.3.3 of the code segment. Package from the input file is read into the string to initialize the menu and menu body. Procedures can be closed so that the title menu disappear, but also can activate a menu (in the menu heading in the menu bar on the horizontal position as a parameter) to make the menu appear.)

VC下的屏幕画图：VC下的屏幕画图程序，有六种方法实现(VC under the screen drawing program, there are six ways to achieve)

该程序实现圆拟合，对学习圆拟合有一定帮助。(circle fit based on VC++)
