选择线附近文字
目前有一串代码，选择线附近文字，有几个缺点，麻烦论坛改善，谢谢！缺点：1.只能选择多段线附近文字；2.文字与线的距离不可调速；3.只能选择一条线附近的文字，不能选择多条线；4.只能选择视图内的文字，超出视图的文字不能选择。(defun c:xw()
(setq cmd (getvar "cmdecho"))
(setvar"cmdecho" 0)
(if (progn
(princ "\n请选取多段线:")
(setq ssa (ssget ":S" '((0 . "lwpolyline,pline"))))
)
(progn
(setq ent (ssname ssa 0))
(setq dxf (entget ent))
(setq pts (mapcar 'cdr (vl-remove-if '(lambda(x)(/= (car x) 10)) dxf)))
(setq ptmin (mapcar '+ (apply 'mapcar (cons 'min pts)) '(-1 -1)))
