frescoabeyta Posted October 24, 2015 Share Posted October 24, 2015 When trying to open a drawing file in AutoCAD, the following message appears: Drawing file is not valid. Anyone else having this issue? Link to comment Share on other sites More sharing options...
David Bethel Posted October 24, 2015 Share Posted October 24, 2015 It usually means that drawing was saved in a newer format. ie you have 2010. you cannot open a dwg file in 2014 format -David Link to comment Share on other sites More sharing options...
ReMark Posted October 24, 2015 Share Posted October 24, 2015 You can download DWG TrueView from the AutoDesk website, for free, and use it to open the file and then save it to the file format of the version of AutoCAD you are currently using.

NoeDePaz Posted October 26, 2015 Share Posted October 26, 2015 (edited) Start by verifying that the drawing file you are trying to open was not created in a newer version of AutoCAD, with a newer file format than the version you are currently using. For example, a drawing created in AutoCAD 2015 will not open in AutoCAD 2012. Refer to AutoCAD drawing file formats for specific details on the file formats supported by various AutoCAD releases. If this turns out to be the issue, request that the drawing be saved to a version that is compatible with the AutoCAD you are using. Otherwise, this message indicates that the drawing file has been damaged beyond use. However, there are a few things that may get it to open: Try to open the drawing file directly instead of using the Recent Documents menu. Check that the storage location that holds the drawing is working properly. Use the RECOVER and RECOVERALL commands on the drawing. Attempt to insert the damaged file into a clean drawing or template using the INSERT command. When none of the above work, try to locate a backup file (.bak) or the latest automatic save file (.sv$) for the drawing, or recover the file from another computer or from a file backup system that you may have in place to help manage your files. The AutoCAD backup file is usually found in the same folder as the DWG. The auto-save file is located in your user temp folder. Any easy way to open this up is to type %tmp% in the location bar of any folder window or in the search field within the Start menu. Rename the .bak or .sv$ extension to .dwg Edited October 30, 2015 by Cad64 Removed Link Link to comment Share on other sites More sharing options...
