Hello
I appreciate your effort, of course, dont doubt it. Looking for some time here in the forum (i think i found it here), i tested a very interesting tool. It's a dll file, so write "netload" inside autocad, select the file and then write myxrefmanager. Test it
pd: the error also could be the language (i dont have english autocad, so i have had to recode some lisps to fit my language)
Thanks.
