CXDIMRESET清理版本 1.0.0已在 AutoCAD 中测试
把手改过的标注文字恢复成测量值
找出被手动改过文字的标注，把真实的测量值放回去，数字重新值得信赖。
怎么用
- 先选择标注，或输入 CXDIMRESET 再选择。
- 文字被覆盖的标注会被重置。
- 报告告诉你改了多少个。
需要知道
- 已经显示测量值的标注不会被改动。
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：CXDIMRESET。
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。
