请问公差里面,明明是输入了+号的,为什么不显示+号呢,-号就有显示
再改一下 - (defun C:G5 ()
- (if (and
- (if (setq t11 (getreal
- (strcat "\n请指定上限公差值+" (if t1 (strcat "<" (rtos t1 2) ">: ") ": "))))
- (setq t1 t11) t1
- )
- (if (setq t21 (getreal
- (strcat "\n请指定下限公差值-" (if t2 (strcat "<" (rtos t2 2) ">: ") ": "))))
- (setq t2 t21) t2
- )
- (princ "\n选择尺寸: ")
- (setq ss (ssget '((0 . "DIMENSION")))))
- (progn
- (setq t1f (if (> t1 0) "+" ""))
- (setq t2f (if (> t2 0) "+" ""))
- (if (equal t1 t2 1e-6)
- (setq txt (strcat "<>%%P" (rtos t1 2)))
- (setq txt (strcat "<>{\\H0.7x;\\S" t1f (rtos t1 2) "^" t2f (rtos t2 2) ";}"))
- )
- (repeat (setq i (sslength ss))
- (setq ent (entget(ssname ss (setq i (1- i)))))
- (entmod (subst (cons 1 txt) (assoc 1 ent) ent))
- )
- ))
- (princ)
- )
