多线段标注
本帖最后由 o宠虫飞/;!★ 于 2014-5-13 12:22 编辑多线段标注 要求字头统一朝上或朝左，而且在线内侧如图，怎么用程序实现？标注是好实现就是字头的方向和在线内的情况我搞不定，求高人指点，谢谢！!
这个不算很难啊。。。自己找找 关于多线段 关键是 字头的方向和在线内，而且线的方向是不固定的！ (defun c:pdim(/ plSet pLlst vLst oldOsn cAng cDis cPt)
(princ "\n<<< Select LwPolyline for dimensioning >>> ")
(if(setq plSet(ssget '((0 . "LWPOLYLINE"))))
(progn
(setq pLlst(vl-remove-if 'listp
(mapcar 'cadr(ssnamex plSet)))
oldOsn(getvar "OSMODE")
); end if
(setvar "OSMODE" 0)(setvar "CMDECHO" 0)
(command "_.undo" "_be")
(foreach pl pLlst
(setq vLst(mapcar '(lambda(x)
(trans x 0 1))(mapcar 'cdr
(vl-remove-if-not
'(lambda(x)(= 10(car x)))(entget pl))))
); end setq
(if(equal '(70 . 1)(assoc 70(entget pl)))
(setq vLst(append vLst(list(car vLst))))
); end if
(while(< 1(length vLst))
(setq cAng(angle(car vLst)(cadr vLst))
cDis(/(distance(car vLst)(cadr vLst))2))
(if(>=(caar vLst)(caadr vLst))

动手修该一下吧 标注倒是好上就是调整位置，感谢提供方法可是没达到效果。 稍微改了一下
