现要知道转换参数才行的。我用lisp弄了一个很简单的 (defun c:zh();将54系转换为苏州独立坐标系 ;(startapp "e:/zbzh.exe") ;(command "delay" 10000);延迟时间 ;(setq cswj "e:/cswj.txt") ;(setq fp3 (open cswj "r")) ;(setq jd (atof (read-line fp3))) ;(setq x0 (atof (read-line fp3))) ;(setq y0 (atof (read-line fp3))) ;(close fp3) (setq jd 旋转角度) (setq jd (* jd 0.017453292)) (setq y0 Y方向平移) (setq x0 X方向平移) (setq cs (cos jd )) (setq si (sin jd )) (setq kkk 0.999973920009) (setq a1 (ssget "X")) (setq shumu (sslength a1)) (setq j 0) (setq tj 0) (repeat shumu (setq a2 (ssname a1 j)) (setq a (entget a2)) (setq n (length a )) (setq kk 0) (repeat n (setq m (nth kk a)) (if (= (car m) 10) (progn (setq tj (+ tj 1)) (setq p1 (cdr m)) (setq y11 (car p1)) (setq x11 (cadr p1)) ;(setq x1 (- (+ x0 (* k ( * x11 cs))) (* y11 si))) ;(setq y1 (+ (+ y0 ( * x11 si)) (* y11 cs))) (setq x1 (- (+ x0 (* kkk (* x11 cs))) (* kkk (* y11 si)))) (setq y1 (+ (+ y0 (* kkk (* x11 si))) (* kkk (* y11 cs)))) (setq p1 (list y1 x1)) (setq b1 (nth kk a)) (setq b2 (cons 10 p1)) (setq a (subst b2 b1 a)) (entmod a) ) ) (if (= (car m) 11) (progn (setq tj (+ tj 1)) (setq p1 (cdr m)) (setq y11 (car p1)) (setq x11 (cadr p1)) (setq x1 (- (+ x0 (* kkk( * x11 cs))) (* kkk (* y11 si)))) (setq y1 (+ (+ y0 (* kkk( * x11 si))) (* kkk (* y11 cs)))) (setq p1 (list y1 x1)) (setq b1 (nth kk a)) (setq b2 (cons 11 p1)) (setq a (subst b2 b1 a)) (entmod a) ) ) (setq kk (+ kk 1)) ) ;一个实体计算完毕,开始下一个循环。 (setq j (+ j 1)) ) (princ) ) |
