When trying to open a drawing file in AutoCAD, the following message appears: 
Drawing file is not valid.

  

Anyone else having this issue?

It looks like you might be trying to open a drawing saved to a different .dwg version than what you are running.  For example, the drawing was created and saved in AutoCAD 2015 file format.

Further information regarding this error message can be found here...

If it is a matter of a corrupt drawing you should read this article...

I get that when trying to open a drawing in a newer version [not just a different version] than what I have.  If that's the issue, Download AutoDesk's free DWG TrueView program, which can convert .DWG files to earlier formats -- download the drawing rather than trying to open it directly, convert it with DWG TrueView, and then you can open it.

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  http://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/AutoCAD-drawing-file-format.html" rel="nofollow -  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.
Also i can suggest to use online service   http://onlinefilerepair.com/en/autocad-repair-online.html" rel="nofollow - https://onlinefilerepair.com/en/autocad-repair-online.html
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 and then you should have

I would not recommend using an online service to repair a corrupted AutoCAD file.  Otherwise, all the information stanley offered was already covered in previous posts one way or the other.
