仿真，装配，干涉检验，仿真，装配，干涉检验，等(Simulation program, interference testing, assembly, installation)

提取横断面数据，直接横断面图数字化，获取高程偏距资料。(Extraction of cross-sectional data, direct digital cross-sectional view, access to information elevation offset.)

建立了一个0.4MW的光伏电站，能够并入10kV电网运行。并且在发生故障时，能够实现低电压穿越。(A 0.4MW PV power station was built and can be incorporated into the 10kV grid operation. And in the event of a fault, low voltage ride through can be achieved.)

VBA对cad的二次开发 vba基础理论 vba源代码集合 有兴趣可以多看看(VBA for the secondary development of cad vba vba source code-based theory who are interested can see more of the collection)

说明：  破解版，CAD快速命令，完美绝对新手操作问题。(draw designs, maps, etc ; picture)

CAD的基础教程，十分适合新手学习，希望可以帮助到大家(CAD-based tutorial, very suitable for beginners to learn, I hope you can help to)

利用pyautocad函数包，实现在AutoCAD中批量生成1：2000图廓。

说明：  低版本打开高版本CAD文件 不想装高版本的CAD可以使用(Low Version Opens High Version)

说明：  netDxf是一个用C＃编程的.net库，用于读写AutoCAD dxf文件。 它支持文本和二进制格式的AutoCad2000，AutoCad2004，AutoCad2007，AutoCad2010，AutoCad2013和AutoCad2018 dxf数据库版本。 该库易于使用，我试图使程序尽可能简单，例如，您不需要使用图层，样式或线型定义填充表格部分。 每次添加新项目时，DxfDocument都会处理这个问题。(netDxf is a .net library programmed in C# to read and write AutoCAD dxf files. It supports AutoCad2000, AutoCad2004, AutoCad2007, AutoCad2010, AutoCad2013, and AutoCad2018 dxf database versions, in both text and binary format. The library is easy to use and I tried to keep the procedures as straightforward as possible, for example you will not need to fill up the table section with layers, styles or line type definitions. The DxfDocument will take care of that every time a new item is added.)

自动归整cad线条，快捷键可以自己修改（在源码顶部）(Cad to surrender the whole line, shortcut keys can modify their own (in the source at the top))
