AutoLisp Vlisp 函数

说明：  cadvba，实现手动添加图元到选择集的代码(Manually adding elements to a selection set)

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))

很实用的vlisp开发小助手，代码自动生成(Very practical VLISP development assistant, automatic code generation)

说明：  范围内选数，这个在核板配筋、柱底轴力的时候特别好用。(This is especially useful in the reinforcement of core plate and the axial force at the bottom of column.)

CAD 文件的读取程序，读取你需要的信息(CAD file reading program, read the information you need)

几何造型库OpenCASCADE自带的例子,可以导入导出IGES/STEP格式的CAD文件,增加了用qtcreator打开工程文件的脚本文件(Geometric modeling library OpenCASCADE own example, you can import and export IGES/STEP format CAD files, increasing the use qtcreator script file to open the project file)

说明：  必備LISP 各類型放樣程式 計算程式 幻燈片選取(Selection of Slides for Calculating Programs of Various Types of Lofting Programs in LISP)

在测绘工作中，难免会遇到要连接边界点的情况，本代码简单易懂，适合初学者学习，连接边界点十分快速有效。

本人所做基于pscad的轻型高压输电模型，可以用来参考一下(I made based on the high-voltage transmission model pscad light, can be used to refer to)

自动创建CAD图层，基本代码仅供学习参考，谢谢(Automatically create the CAD layer)
