Question

请高手用AutoLISP编写小程序

求高手编一个扫孔坐标的程序 （要选孔的时候可以根据大小孔进行筛选不用一个一个选的）最后用ABCD等字母分别表示 就像有一个CD程序差不多的那种！

Answer 1

（一）
(defun c:tuxing1 ()
(setq Rd (getdist "\n R=:"))
(setq Rx (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq p1 (list(car p0) (+ (+ (cadr p0) Rd) 5)))
(setq p2 (list(- (- (car p0) Rd) 5) (cadr p0)))
(setq p3 (list(car p0) (- (- (cadr p0) Rd) 5)))
(setq p4 (list(+ (+ (car p0) Rd) 5) (cadr p0)))
(Command "line" p1 p3"")
(Command "line" p2 p4"")
(Command "circle" p0 Rd)
(Command "circle" p0 RX)
)
（二）
(defun c:tuxing2 ()
(setq Rd (getdist "\n R=:"))
(setq Rx (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq a1 (list(+ (car p0) (* (cos (/ pi 4)) Rx)) (+ (cadr p0) (* (cos (/ pi 4)) Rx))))
(setq a2 (list(- (car p0) (* (cos (/ pi 4)) Rx)) (cadr a1)))
(setq a3 (list(car a2) (- (cadr p0) (* (cos (/ pi 4)) Rx))))
(setq a4 (list(car a1) (cadr a3)))
(setq b1 (list(+ (car p0) (* (cos (/ pi 4)) Rd)) (+ (cadr p0) (* (cos (/ pi 4)) Rd))))
(setq b2 (list(- (car p0) (* (cos (/ pi 4)) Rd)) (cadr b1)))
(setq b3 (list(car b2) (- (cadr p0) (* (cos (/ pi 4)) Rd))))
(setq b4 (list(car b1) (cadr b3)))
(Command "line" a1 a2 a3 a4 a1"")
(Command "line" b1 b2 b3 b4 b1"")
(Command "circle" p0 Rd)
(Command "circle" p0 RX)
)
（三）
(defun c:tuxing3 ()
(setq r (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq p1 (list(- (car p0) (* r 2)) (cadr p0)))
setq p2 (list(+ (car p0) (* r 2)) (cadr p0)))
((Command "circle" p0 r)
(Command "circle" p1 r)
(Command "circle" p2 r)
)
（四）
(defun c:tuxing4 ()
(setq r (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq a1 (list(+ (car p0) (* (cos (/ pi 4)) r)) (+ (cadr p0) (* (cos (/ pi 4)) r))))
(setq a2 (list(- (car p0) (* (cos (/ pi 4)) r)) (cadr a1)))
(setq a3 (list(car a2) (- (cadr p0) (* (cos (/ pi 4)) r))))
(setq a4 (list(car a1) (cadr a3)))
(Command "line" a1 a2 a3 a4 a1"")
(Command "circle" p0 r)
）
可以了，你试试吧！

(Defun C:T914 (/ lstCir i item strA)
(Defun GetCir (/ lstSS ss lstRet i en enData r pt)
(princ "\n请选择圆：")
(setq lstSS '((0 . "CIRCLE")))
(setq ss (vl-catch-all-apply 'ssget (list lstSS)))
(cond ((or (null ss) (vl-catch-all-error-p ss)) (vl-exit-with-value 0)))
(setq lstRet '())
(setq i 0)
(repeat (sslength ss)
(setq en (ssname ss i)
i (1+ i)
enData (entget en)
r (cdr (assoc 40 enData))

(if (assoc r lstRet)
(progn
