複製下面的指令碼到命令列回車即可載入,輸入pldd,程式會提示選擇pline,選擇pline後會列印所有的三維座標
(defun c:pldd (/ wb cc ss1 aa pts bhbz ent)
(setq ent (car (entsel "\n請選擇pline")))
(setq wb (entget ent) cc nil bhbz (cdr (assoc 70 wb)) )
(cond
((= (cdr (assoc 0 wb)) "polyline")
(setq ss1 (entnext ent))
(while (/= ss1 nil)
(setq aa (entget ss1))
(if (= (cdr (assoc 0 aa)) "vertex") (progn
(setq aa (cdr (assoc 10 aa)))
(if (/= aa nil) (progn
(if (= (length aa) 2)
(setq aa (list (car aa) (cadr aa) 0.0) )
)(if (= cc nil)
(setq pts aa)
)(setq cc (cons aa cc))
))(setq ss1 (entnext ss1))
)(setq ss1 nil)))
(if (= bhbz 1)
(setq cc (cons pts cc))))

(setq wb (member (assoc 10 wb) wb))

貼上這個**就可以實現獲取圓心座標

求一個lisp程式,關於提取cad影象座標
4樓:設計人生
方案一:直接讀取dwg格式檔案有點難度,估計高手會做方案二:若是檔案有很多要做的話,可以用c#,c++,vb通過com去開發,用com方式依次開啟dwg圖檔,然後遍歷圖元來進行你的要求來運算
方案三:若是檔案有很多要做的話,也可以用autolisp來做,自動開啟你的檔案列表,然後遍歷圖元來進行你的要求來運算
方案四:若是檔案不是很多的話,也可以手動開啟dwg檔案,然後編寫lisp函式遍歷圖元來進行你的要求來運算
或者你發一些cad參考圖檔給我,我來幫你看看到底怎麼做合適若是覺得滿意的話還請採納
求助:如何用lisp讀取cad中許多散點的座標
5樓:
請檢視附件,寫的lisp程式,輸入tt執行程式,批量選擇cad中的點,然後將座標寫入txt檔案。
指定儲存檔案的位置及名稱,然後選擇點就歐克了。
