经常会遇到不同图纸粘贴块参照的现象,如果两个图纸中相同块名其结构不同,粘贴会出问题,这里给出来一种方法,可以降低重复几率
- (defun $make-block-name$ (/ $msec/52$ f m n r s str wm y zz)
- ;制作块名
- (defun $msec/52$ (n zz / d ds loop n1 str)
- ;52进制转换为字母
- (or n
- (setq n (atoi (menucmd "M=$(edtime,$(getvar,date),MSEC)")))
- )
- (setq ds nil)
- (setq loop T)
- (while loop
- (if (= (setq n1 (/ n 52)) 0)
- (setq loop nil)
- )
- (setq d (rem n 52))
- (setq ds (cons d ds))
- (setq n n1)
- )
- (setq
- str (apply 'strcat
- (mapcar (function (lambda (a) (nth a zz))) ds)
- )
- )
- str
- )
- (SETQ ZZ (list "A" "B" "C" "D" "E" "F" "G" "H" "I"
- "J" "K" "L" "M" "N" "O" "P" "Q" "R"
- "S" "T" "U" "V" "W" "X" "Y" "Z" "A"
- "a" "b" "c" "d" "e" "f" "g" "h" "i"
- "j" "k" "l" "m" "n" "o" "p" "q" "r"
- "s" "t" "u" "v" "w" "x" "y" "z" "a"
- )
- )
- (setq
- n ($msec/52$
- (atoi (menucmd "M=$(edtime,$(getvar,date),YYYY)"))
- zz
- )
- ) ;年
- (setq y (nth (atoi (menucmd "M=$(edtime,$(getvar,date),M)")) zz))
- ;月
- (setq R (nth (atoi (menucmd "M=$(edtime,$(getvar,date),D)")) zz))
- ;日
- (setq s (nth (atoi (menucmd "M=$(edtime,$(getvar,date),HH)")) zz))
- ;时
- (setq F ($msec/52$ (atoi (menucmd "M=$(edtime,$(getvar,date),MM)"))
- zz
- )
- )
- ;分
- (setq M ($msec/52$ (atoi (menucmd "M=$(edtime,$(getvar,date),SS)"))
- zz
- )
- ) ;秒
- (SETQ WM ($msec/52$ NIL zz)) ;微妙
- (setq str (strcat n y r S F M WM))
- str
- )
