编了一个提取标注的尺寸,并替换文本的程序,适用于线性、对齐、半径、直径、角度和弧长标注。
注:弧长标注老版本的cad,比如04版之类的,没这个功能。- (defun C:DimReplace( / dim bl jd len diment dimss dimty )
- (princ "\n选择标注: ")
- (setq dim (ssget '((0 . "DIMENSION"))))
- (setq bl (getreal "\n标注比例: <1>"))
- (if (not bl) (setq bl 1))
- (setq jd (getint "\n标注精度: <0>"))
- (if (not jd) (setq jd 0))
- (if dim
- (progn
- (repeat
- (setq len (sslength dim))
- (setq diment (entget (ssname dim (setq len (1- len)))))
- (setq dimss (cdr (assoc 1 diment)))
- (if (or (= dimss "") (= dimss "<>"))
- (progn
- (setq dimty (cdr (assoc 70 diment)))
- (setq dimss (cdr (assoc 42 diment)))
- (cond
- ( (or (= dimty 32) (= dimty 160);线性
- (= dimty 33) (= dimty 161);对齐
- (= dimty 37) (= dimty 165);弧长
- )
- (setq dimss (rtos (* dimss bl) 2 jd))
- )
- ((or (= dimty 34) (= dimty 162));角度
- (setq dimss (strcat (rtos (WYB-rtod dimss) 2 jd) "%%D"))
- )
- ((or (= dimty 35) (= dimty 163));直径
- (setq dimss (strcat "%%C" (rtos (* dimss bl) 2 jd)))
- )
- ((or (= dimty 36) (= dimty 164));半径
- (setq dimss (strcat "R" (rtos (* dimss bl) 2 jd)))
- )
- )
- (entmod (subst (cons 1 dimss) (assoc 1 diment) diment))
- )
- )
- )
- )
- )
- (princ "\n完成标注的文本替换")
- (princ)
- )
- (defun WYB-rtod(r)
- (/ (* r 180) pi)
- )
