CXLAYMRG图层版本 1.0.0已在 AutoCAD 中测试
合并图层并删除多余的图层
把所选对象所在各图层上的全部内容移到你再点击的那个对象所在的图层，然后删除已经空掉的图层。
怎么用
- 输入 CXLAYMRG，选择要合并掉的图层上的对象。
- 点击要并入的那个图层上的一个对象。
- 所有内容移过去，空图层被删除。
需要知道
- 图层 0、Defpoints、目标图层和当前图层永远不会被删除。
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：CXLAYMRG。
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。
