CXLAYSEL图层版本 1.0.0已在 AutoCAD 中测试
选择你点选对象所在图层上的全部对象
选中你所点对象所在图层上的所有对象（当前选项卡内），便于一起移动、复制或修改。
怎么用
- 输入 CXLAYSEL，在每个需要的图层上各选一个对象。
- 这些图层上的所有对象都被选中。
- 接着执行任何命令，比如 MOVE 或 PROPERTIES。
需要知道
- 在当前模型空间或布局选项卡中查找。
在 AutoCAD 中加载
- 把文件保存在任意位置。
- 输入 APPLOAD，选择文件，点“加载”。
- 输入命令名：CXLAYSEL。
想每次启动都可用，在同一个对话框里加入“启动组”，或用可选的加载器一次加载整个文件夹。 关于可选的加载器
已在 AutoCAD（完整版）中测试。其他能运行 AutoLISP 的软件也许可用，但未经测试。
