怎么判断图纸中是否存在外部参照
RT,关于外部参照的函数不熟,请各位前辈教一下 check here:http://discussion.autodesk.com/thread.jspa?messageID=1131046 Andyhon 发表于 2014-9-15 11:10 static/image/common/back.gif

这..英文水平不行,看百度翻译都看得倒懂不懂的,谢谢了 大概看懂点,
setq ss (ssget "x" (list (cons 0 "insert")(cons 2 "*"))))
If the selection set is nil, there are no xrefs, otherwise
(sslength ss) tells you how many objects are attached
xrefs.
这句命令为何和他描述的不一样...有参照和没参照SS都不是nil Reply From: Bethel, David
Re: Check if Xref's exist in drawing
Ron,
via Lisp;
(defun FindXref (/ td xrf)
(while (setq td (tblnext "BLOCK" (not td)))
(and (= (logand (cdr (assoc 70 td)) 4) 4)
(setq xrf (cons (strcase (cdr (assoc 2 td))) xrf))
)
)
xrf
)

(vlax-for a (vla-get-blocks (vla-get-ActiveDocument (vlax-get-acad-object)))
(if (= :vlax-true (vla-get-IsXRef a))
(princ "\n图形有外部参照...")
)

G版,请教下,如何判断一个块是块参照还是外部参照啊?
找到一个,不知道可以不
(setq *adoc* (vla-get-activedocument (vlax-get-acad-object)))
(setq blk (car (entsel)))
(= :vlax-true (vla-get-isxref (vla-item (vla-get-blocks *adoc*) (cdr (assoc 2 (entget blk))))))
