XREF dxf code

[cadconcepts]

Hi All-

I took a quick look at the developers help file in an effort to find out how I could determine if an inserted block was an xref and whether it was clipped with no luck at all. If anyone knows how I can go about obtaining this information via LISP please let me know. Thanks.

Try this...


(defun isXref (blkname)
(and (setq r (tblsearch "BLOCK" blkname))
(eq 4 (logand 4 (cdr (assoc 70 r))))
)
)


To tell if the xref is clipped, see this:
