全部 LISP 指令

CXLAYOFF圖層版本 1.0.0已在 AutoCAD 中測試

關閉你點選物件所在的圖層

選取物件,一步關掉它們所在的圖層,不用開啟圖層管理器。

如何使用

  1. 先選擇物件,或輸入 CXLAYOFF 再選擇。
  2. 它們所在的圖層被關閉。
  3. 需要時用圖層管理器或 CXLAYRES 重新開啟。

請注意

  • 當前圖層永遠不會被關閉。

在 AutoCAD 中載入

  1. 把檔案存在任意位置。
  2. 輸入 APPLOAD,選擇檔案,按「載入」。
  3. 輸入指令名稱:CXLAYOFF。

想每次啟動都可用,在同一個對話方塊中加入「啟動套件」,或用選用的載入器一次載入整個資料夾。 關於選用的載入器

已在 AutoCAD(完整版)中測試。其他能執行 AutoLISP 的軟體也許可用,但未經測試。
