CXPTS匯出與匯入(CSV)版本 1.0.0已在 AutoCAD 中測試
按 CSV 檔案繪製帶名稱的點
從電子表格檔案繪製測量風格的點:名稱、X、Y 和可選的 Z 變成一個點,名稱寫在它旁邊。
如何使用
- 準備一個 CSV,列為名稱、x、y,可選 z。
- 輸入 CXPTS,選擇該檔案。
- 點和名稱出現在當前圖層上。
請注意
- 執行期間點樣式臨時設為清晰的十字,結束後恢復。
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:CXPTS。
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 cxpts.lsp 的檔案,或直接下載。
