NBC Posted December 2, 2009 Posted December 2, 2009 Perhaps a newer version of CAD created the file than the version that you are trying to open it with ? Quote

AlinOz Posted December 3, 2009 Posted December 3, 2009 I am having trouble opening a drawing. I can see it in the preview but when i click on open it reads drawing not vaild? Something may have gone awry with the drawing - try using the RECOVER command to have AutoCAD run through the drawing Database to find any issues and open it. Hopefully that may solve it for you Quote
Cad64 Posted December 3, 2009 Posted December 3, 2009 Where did this drawing come from? How do you know it was saved in 2004 format? That error generally means the drawing was saved in a later format that your version cannot open. Either that or the drawing file is corrupt. You could download the free DWG TrueView software and then try converting the drawing yourself, to make sure it is actually 2004 format. Quote
CJJ Posted December 3, 2009 Posted December 3, 2009 I agree with Cad64, go download Trueview. When I run into drawings that don't open properly with AutoCAD, I just convert it back to a previous file format (typically I start with DWG 2000 format, but try them all until you find one that works).

Coosbaylumber Posted December 3, 2009 Posted December 3, 2009 I am having trouble opening a drawing. I can see it in the preview but when i click on open it reads drawing not vaild? Have run into this a number of times over past decade or two. If you received the drawing via the internet, I used to find some devious one would change the file extension on some picture to some DWG format just so that it did not then get altered. Change back and it opened up (as a picture). Alternately, open up the drawing in Wordpad (NOT Autocad) or something simple, and see what is printed on very first page, as the header. If wrong data is noted, like wrong version actually got saved, then it will not open up. Do not save anything when exiting. If the genious saved the drawing as a 2004 format, but continued on working, it then got altered and saved as a later version then. Not what you think, based upon their conversation. The little opening up image is just that. It is only a preview, saved in some secret file, and not the actual file which can be edited then. Wm. Quote
