Is there any way to disable the "would you like to open the file read only?" alert window when I open a read only file?
Popping up a modal alert which requires of a user to confirm if he or she would indeed like to open a drawing is just plain bad UI. In fact it's dumb. The user may have just double-clicked on the drawing file in Windows Explorer or have just initiated opening via the File|Open dialog...either way signalling his/her intent to open the file (regardless of whether or not it's read-only). And in a networked corporate enviornment, most users will almost always already know that a target file on a restricted network share will be opened read-only. They already know because they do it so frequently. So why needlessly pester them again with a blocking modal reminder. After all the file isn't loading until the alert is manually dismissed. I at least find this behavior extremely annoying!
Microsoft Office applications by contrast handle this situation much better by simpling opening the file and reporting in the title-bar that it's opened in read-only mode. Later, when the user attempts to save it (that is--and this is an important point--if the user attempts to save it), he or she will be reminded then that the file is read-only and that an elevation to read-write mode or a save-as operation is required.
The tacit assumption in AutoCAD's behavior here is that the primary reason for opening a document is to edit it. But of course this assumption is totally incorrect: documents are far more frequently consumed (read/browsed/viewed) than they are edited (and even so in expensive editors like AutoCAD). At any rate, if they are opened to be edited when on a protected network share, they must be saved off to an unprotected share.
But if it's any consolation to the good folks at AutoDesk, Pro/E's behaviors are infinitely worse than AutoCAD's. Constantly and everywhere in the UI, Pro/E pesters the user to confirm if he/she intended to do the very thing that he/she just told Pro/E to do. If AutoCAD's bothersome behavior is annoying (and for me it is), Pro/E's is utterly infuriating.
But alas, I rant.
I will strongly advise to open the file, READ ONLY, and to save it, SAVE AS, with a new name. The last person who did this new what he was doing: doesn’t wand like some one to change it if is not protected.
I don't really understand you. Have you even read my starter post? Calvindale gathered everything I could add. I just like a MS Office behavior, too.
They are not, indeed. MS Office costs about 180€+, AutoCAD itself costs 1800€+, so there should be an option to turn off that stupid warning. Opening a lot of read-only files and pressing YES to every single one isn't that fun. Same, if I save a drawing in DXF format, a warning pops up into my face on closing "Do you really that stupid? Do you really need that DXF? There's the brand new DWG format instead! Save it in DWG, OK?" NOOOOOOO, NOT OK!
Since you have no need to edit or save edits, test the free viewer from Autodesk and see if that solves your issue.
Remember, AutoCAD defaults to DWG and not DXF: it's not a DXF editor. You'll need to find a software that only does DXF editing (nothing from Autodesk I believe).
I have to make DXFs from DWGs, and these DWGs are exported Inventor files, because our machines can only process DXFs, so we store flat patterns in DXF format. Yes, sometimes I have to save (as) a read-only file, so the viewer isn't an option (and I don't like that). I'd rather keep pressing Y or N
