MDP Posted June 4, 2009 Share Posted June 4, 2009 I lost a portion of a dwg. and downloaded a file from our backup service. When I try and open the file in Autocad, the messenger says "drawing file is not valid". any suggestions would be greatly appreciated.

chelsea1307 Posted June 4, 2009 Share Posted June 4, 2009 did you change the extension type of the file? is it still a bak or is a dwg? Quote Link to comment Share on other sites More sharing options...
MDP Posted June 4, 2009 Author Share Posted June 4, 2009 no i did not change the file type, It says it is a autocad drawing file and is represented by the typical dwg icon Quote Link to comment Share on other sites More sharing options...
chelsea1307 Posted June 4, 2009 Share Posted June 4, 2009 have you tried typing recover in the command line and selecting that dwg? Quote Link to comment Share on other sites More sharing options...

chelsea1307 Posted June 4, 2009 Share Posted June 4, 2009 could you post it here and see if someone can open it Quote Link to comment Share on other sites More sharing options...
JerryG Posted June 4, 2009 Share Posted June 4, 2009 I think it is a simple matter of the file is from a newer version of autocad. Download the new Design Review 2010 and use that to convert the file to your version. Quote Link to comment Share on other sites More sharing options...
MDP Posted June 4, 2009 Author Share Posted June 4, 2009 Thank you all for the responses I am new to this site and will post the file soon. I had to just jump back at it and reproduce the detail. Our real concern is that the file was supposed to be an exact copy of what we had on our server last night. We use Ibackup as a remote backup service and they assured me the file should not have be modified or corrupted by them. I will continue trying and post any progress made. thanks again.mdp Quote Link to comment Share on other sites More sharing options...
chelsea1307 Posted June 4, 2009 Share Posted June 4, 2009 I thought you were using an autocad *.bak file, that explains alot Quote Link to comment Share on other sites More sharing options...
stevenlyons Posted January 7, 2010 Share Posted January 7, 2010 Hello This is a temporary solution to the issue i had when opening a drawing in CAD2010 that was created in an older version. I would get the AutoCAD Message - Drawing file is not valid. Well, for some reason, don't ask me why, when i email the drawing to my hotmail account (haven't tried it on outlook, it may work) and open it from hotmail it works!? As i said, this is a temporary solution as it is a pain having to do this every time so please please post the perminent solution to this problem Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 7, 2010 Share Posted January 7, 2010 We heard you the first time. Try using Design Review 2010 as previously suggested. Quote Link to comment Share on other sites More sharing options...

one25IT Posted November 23, 2011 Share Posted November 23, 2011 I know this an old thread, but I just had the same problem. Here's the file 15_Prodex_ConcealedFixingWithHangingProfiles_Mounting_2009.11.04-1.dwg which I just downloaded from this source http://www.prodema.com/en/autocad-downloads/. That's what I tried so far: I am using the latest version of Autocad I tried recovering from within Autocad I tried opening with Design Review I tried opening with True View Any further ideas?

ReMark Posted November 23, 2011 Share Posted November 23, 2011 What program was the file created with? Quote Link to comment Share on other sites More sharing options...
memphis710 Posted November 24, 2011 Share Posted November 24, 2011 Looking at the file it shows as AC1018 which is 04, 05 and 06 autocad (if it was autocad at all). I downloaded the file and had the same issue as the OP. I did notice however, that when in recovery, windows could show a preview of the file so it is in there somewhere.....

one25IT Posted November 24, 2011 Share Posted November 24, 2011 Yes, I noticed that too, that I could see a drawing preview. Quote Link to comment Share on other sites More sharing options...
