幾個(gè)很有用的CAD的lisp程序
1、計(jì)算CAD圖形中所有線(xiàn)段總長(zhǎng)度(加載后只需框選所有線(xiàn)段便可得出這些線(xiàn)段的總長(zhǎng)度)
(defun c:LL ()
(setvar "cmdecho" 1)
(setq en (ssget (list '(0 . "spline,arc,line,ellipse,LWPOLYLINE"))))
(setq i 0)
(setq ll 0)
(repeat (sslength en)
(setq ss (ssname en i))
(setq endata (entget ss))
(command "lengthen" ss "")
(setq dd (getvar "perimeter"))
(setq ll (+ dd ll))
(setq i (1+ i))
)
(princ "所選線(xiàn)條總長(zhǎng)為:")(princ ll)(princ)
)
2、標(biāo)注CAD圖形中所有線(xiàn)段(加載后只需框選所有線(xiàn)段便可得標(biāo)注這些線(xiàn)段)
(defun c:LLL ()
(COMMAND "UCS" "")
(setvar "cmdecho" 1)
(SETVAR "OSMODE" 0)
(setq AcadObject (vlax-get-acad-object)
AcadDocument (vla-get-ActiveDocument Acadobject)
mSpace (vla-get-ModelSpace Acaddocument)
)
;;選取需要測(cè)量的樣條曲線(xiàn)、圓弧、直線(xiàn)、橢圓
(setq en (ssget (list '(0 . "spline,arc,line,ellipse,LWPOLYLINE"))))
(setq i 0)
;;獲取系統(tǒng)參數(shù)textsize
(setq shh (getvar "textsize"))
(setq str_hh (strcat "\n文字高度 <" (rtos shh 2) ">: "))
(setq hh (getdist str_hh))
(while hh
(setvar "textsize" hh)
(setq hh nil))
;;輸入標(biāo)注文字高度
;;循環(huán)開(kāi)始
(repeat (sslength en)
(setq ss (ssname en i))
(setq endata (entget ss))
(command "lengthen" ss "")
(setq dd (getvar "perimeter"))
(princ (strcat "\n長(zhǎng)度=" (rtos dd 2)))
;;尋找代表圖層的字符串
(setq aa (assoc 0 endata))
;;獲取圖層名稱(chēng)
(setq aa1 (cdr aa))
;;判斷線(xiàn)條種類(lèi)
(cond
((= aa1 "SPLINE")
;;如果是spline
(progn
(setq arcObj (VLAX-ENAME->VLA-OBJECT ss))
(setq startPnt1 (vla-get-ControlPoints arcObj))
(setq p1
(vlax-safearray->list (vlax-variant-value startPnt1))
)
(setq x1 (car p1))
(setq y1 (cadr p1))
(setq z1 (caddr p1))
(setq pp1 (list x1 y1 z1))
(repeat (- (/ (length p1) 3) 1)
;;循環(huán),尋找最后一個(gè)控制點(diǎn)
(setq p1 (cdddr p1))
(setq x2 (car p1))
(setq y2 (cadr p1))
(setq z2 (caddr p1))
)
(setq pp2 (list x2 y2 z2))
)
)
((= aa1 "LWPOLYLINE")
;;如果是LWPOLYLINE
(progn
(setq arcObj (VLAX-ENAME->VLA-OBJECT ss))
(setq startPnt1 (vla-get-Coordinates arcObj))
(setq p1
(vlax-safearray->list (vlax-variant-value startPnt1))
)
(setq x1 (car p1))
(setq y1 (cadr p1))
(setq z1 (caddr p1))
(setq pp1 (list x1 y1 z1))
(repeat (- (/ (length p1) 3) 1)
;;循環(huán),尋找最后一個(gè)控制點(diǎn)
(setq p1 (cdddr p1))
(setq x2 (car p1))
(setq y2 (cadr p1))
(setq z2 (caddr p1))
)
(setq pp2 (list x2 y2 z2))
)
)
(t
;;如果是其他種類(lèi)線(xiàn)條
(progn
(setq arcObj (VLAX-ENAME->VLA-OBJECT ss))
(setq startPnt1 (vla-get-StartPoint arcObj))
;;獲取起點(diǎn)
(setq endPnt1 (vla-get-EndPoint arcObj))
;;獲取終點(diǎn)
(setq pp1
(vlax-safearray->list (vlax-variant-value startPnt1))
)
(setq
pp2 (vlax-safearray->list (vlax-variant-value endPnt1))
)
)
)
)
(setq x1 (car pp1))
(setq y1 (cadr pp1))
(setq z1 (caddr pp1))
(setq x2 (car pp2))
(setq y2 (cadr pp2))
(setq z2 (caddr pp2))
(setq x (/ (+ x1 x2) 2))
(setq y (/ (+ y1 y2) 2))
(setq z (/ (+ z1 z2) 2))
(setq pt (list x y z))
;;取得線(xiàn)段兩端的中點(diǎn)
(setq ang (angle pp1 pp2))
;;獲取角度
(if (> (* (/ ang pi) 180) 180)
(setq ang (+ ang pi))
)
(command "text"
"j"
"bc"
pt
""
(* (/ ang pi) 180)
(strcat "" (rtos dd 2))
""
)
(setq i (1+ i))
)
(prin1)
)
(prompt "\n <>在圖中直接寫(xiě)出長(zhǎng)度")
(prin1)
3、連續(xù)打斷程序
(defun c:br1 ()
(command "break" pause "f" pause "@")
)
4、將CAD文字導(dǎo)入Excel表格
(defun c:Q2()
(setq ffn (getfiled "寫(xiě)出文件" "" "xls" 1))
(princ "\n選取文字...")
(setq ss (ssget))
(setq ff (open ffn "w"))
(setq i 0)
(repeat (sslength ss)
(setq ssn (ssname ss i))
(setq ssdata (entget ssn))
(setq sstyp (cdr (assoc 0 ssdata)))
(if (or (= sstyp "TEXT") (= sstyp "MTEXT"))
(progn
(setq txt (cdr (assoc 1 ssdata)))
(princ txt ff)
(princ "\n" ff)
)
)
(setq i (1+ i))
)
(close ff)
(princ (strcat "\n寫(xiě)出文件: " ffn))
(prin1)
)
5、刪除帶顏色圖元
以下程序在別人的貼子里貼過(guò).為了說(shuō)明問(wèn)題,今天再貼一次。
改顏色的LISP程序
(defun c:c1()(ssget)(command "chprop" "p" "" "c" "1" "") (princ))
(defun c:c2()(ssget)(command "chprop" "p" "" "c" "2" "") (princ))
(defun c:c3()(ssget)(command "chprop" "p" "" "c" "3" "") (princ))
(defun c:c4()(ssget)(command "chprop" "p" "" "c" "4" "") (princ))
(defun c:c5()(ssget)(command "chprop" "p" "" "c" "5" "") (princ))
(defun c:c6()(ssget)(command "chprop" "p" "" "c" "6" "") (princ))
(defun c:c7()(ssget)(command "chprop" "p" "" "c" "7" "") (princ))
(defun c:c8()(ssget)(command "chprop" "p" "" "c" "8" "") (princ))
你用C1 命令就可以將圖元改為紅色了.其余類(lèi)似。
刪除紅色圖元
(defun C:D1 (/ m A M)
(setq m:err *error* *error* *merr*)
(setvar "cmdecho" 0)
(command "UNDO" "G")
(prompt "選擇圖形")
(setq A (ssget '((62 . 1)) ))
(if (/= A nil)(progn
(setq M (sslength A))
(command "erase" A "")
(princ "\n共刪除紅色圖元<")(princ M)(princ ">個(gè)")
))
(command "UNDO" "E")
(princ) )
這樣,鍵入 D1 命令,就可以刪除紅色的圖元了。
