When opening DWG file with TrueView 2011 Fr, messages appear (see attachments) and then TrueView closes whatever option selected.
Is anybody knows something about that, if there is a patch or something missing ?
Your file(s) contains custom AEC content (first message), and your file also contains external reference files that appear to be missing (second message) that you must find and reassociate in order to see the file content correctly.
Both of these questions can be answered best by the person youo got the files from.
