What is "every" command you tried? We need more information. Your post basically says, "My drawing is broken. What will fix it?"&nbsp; We can't just guess with no other information.&nbsp;</P> Mon, 22 Oct 2018 13:17:55 GMT https://forums.autodesk.com/t5/autocad-forum/drawing-file-is-not-valid/m-p/8350176#M161929 gotphish001 2018-10-22T13:17:55Z https://forums.autodesk.com/t5/autocad-forum/drawing-file-is-not-valid/m-p/8350208#M161930 <P>I've tried RECOVER, RECOVERALL, insert as a block, recover from bak, and recover from an autosave file.

Sorry for the assumption but we get many people that say they tried for hours to fix something and really they didn't try much of anything. I did have one more trick up my sleeve of trying to recover it in Archicad. I thought for a second it was going to get it opened, but it failed right at the end. I tried a couple more times to be sure, but I was unable to open it either.&nbsp;</P> Mon, 22 Oct 2018 13:54:39 GMT https://forums.autodesk.com/t5/autocad-forum/drawing-file-is-not-valid/m-p/8350285#M161933 gotphish001 2018-10-22T13:54:39Z https://forums.autodesk.com/t5/autocad-forum/drawing-file-is-not-valid/m-p/8350324#M161934 <P>I can't find any backups that'll work, but thank you anyway.</P> Mon, 22 Oct 2018 14:03:10 GMT https://forums.autodesk.com/t5/autocad-forum/drawing-file-is-not-valid/m-p/8350324#M161934 Anonymous 2018-10-22T14:03:10Z https://forums.autodesk.com/t5/autocad-forum/drawing-file-is-not-valid/m-p/8350329#M161935 <P>thank you for your help anyway.</P> Mon, 22 Oct 2018 14:05:03 GMT https://forums.autodesk.com/t5/autocad-forum/drawing-file-is-not-valid/m-p/8350329#M161935 Anonymous 2018-10-22T14:05:03Z
