CXLAYSEL圖層版本 1.0.0已在 AutoCAD 中測試
選擇你點選物件所在圖層上的全部物件
選取你所點物件所在圖層上的所有物件（當前選項卡內），便於一起移動、複製或修改。
如何使用
- 輸入 CXLAYSEL，在每個需要的圖層上各選一個物件。
- 這些圖層上的所有物件都被選取。
- 接著執行任何命令，比如 MOVE 或 PROPERTIES。
請注意
- 在當前模型空間或佈局選項卡中尋找。
在 AutoCAD 中載入
- 把檔案存在任意位置。
- 輸入 APPLOAD，選擇檔案，按「載入」。
- 輸入指令名稱：CXLAYSEL。
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。
程式碼
純文字，沒有任何隱藏內容。複製後存成名為 cxlaysel.lsp 的檔案，或直接下載。
