五年时间没玩LISP了,年末快要放假了,腾出点时间狂狂论坛,看到不少朋友晒源码,俺也贴出俺以前的自己做的源码与大家分享!
这个最初也是在天河CAD那看到的,就自己做了一个,功能完全达到天河的功能,且还多了一个好玩的东东,不过这个多出的东东无实际用途
这个程序的核心函数为:grread
(defun c:ff ( / ka01 pt1 KENT KENTLIST karc knea ka1 ka2 ka3 ka4 klj pt11 )
(setq ka01 (entsel "请选择直线或圆弧:"))(if ka01
(progn(setq KENT (car ka01))(setq KENTLIST (entget KENT))
(if(not(or(eq "ARC" (cdr(assoc 0 KENTLIST)))(eq "LINE" (cdr(assoc 0 KENTLIST)))))
(princ "\n您选择的不是直线或圆弧!") (progn(princ "\n按右键显示路径.")
(setq pt1 (cadr ka01))(setq KENT (car ka01))(setq KENTLIST (entget KENT))
(if (eq "ARC" (cdr(assoc 0 KENTLIST)))(setq karc t)(setq karc nil))
(setq ka1 (vlax-ename->vla-object KENT))
(if (<(distance pt1 (vlax-curve-getStartPoint ka1))(distance pt1
(vlax-curve-getEndPoint ka1)))(setq knea t)(setq knea nil))
(while ka1
(setq ka2 (grread t 12 2) ka3 (car ka2) ka4 (cadr ka2))
(if (= ka3 25)(if klj(setq klj nil)(setq klj t)))
(cond ((= ka3 5)
(progn (setq pt11 (vlax-curve-getClosestPointTo ka1 ka4 t))
(if(not karc)(if knea
(if (> (distance pt11 (vlax-curve-getEndPoint ka1)) 0.1)
(vla-put-StartPoint ka1 (vlax-3d-point pt11)))
(if(> (distance pt11 (vlax-curve-getStartPoint ka1)) 0.1)
(vla-put-EndPoint ka1 (vlax-3d-point pt11)))
)
(if knea(vlax-put-property ka1 'StartAngle (angle (cdr(assoc 10 KENTLIST))pt11))
(vlax-put-property ka1 'EndAngle (angle (cdr(assoc 10 KENTLIST))pt11))))
(if klj (progn(redraw)(grdraw ka4 pt11 2 4)))
)
)
((= ka3 3)(setq ka1 nil))
;((= ka3 25)(princ ka3)(princ ka4))
;(t (princ ka2)(princ " "))
;(t (princ ka3)(princ ",")(princ ka4)(princ " "))
)) )) )) (redraw) (princ)
