Drawing file is not valid

859 Views, 6 Replies

Having a problem with a .dwg file that I have used in the past, when I try to open, I get the dreaded "Drawing file is not valid".

I have opened in WordPad, and there are many characters, but won't open in ACAD.  Drawing is a ACAD 2009 file, but is slightly too large to post here.

Anybody out there with suggestions?  I can zip the file to about 1.58mB.

Thanks in advance.

Start an empty drawing, type in RECOVER, find this bad drawing.

or

type in WBLOCK, and find this bad drawing.

Thanks again, but

Recover states "unable to recover drawing file",

 

Unsure on settings for WBLOCK, do I select block, drawing, objects? Source drop down is grayed out, but I can select destination to that original file.  When I do that, file is overwritten...I made copies for protection

Drag the drawing icon to a minimized drawing area and drop it (It works same as insert)

 

Do you have .bak of that drawing?

No bak, when I create a new-block.dwg with Wblock, and drag the old drawing onto the model tab, on command line it states: _-INSERT Enter block name or [?]: "F:\backup9-4-10\DENNIS\DMG\rivercrest deck old\12980RIVERCRESTDeck.dwg" ** File F:\backup 9-4-10\DENNIS\DMG\rivercrest deck old\12980RIVERCRESTDeck.dwg was created by an incompatible version of AutoCAD *Invalid* I have used the drawing previously (2011) but now it seems corrupted.

I apologize for the extraneous information on previous reply.

 

Is there some way to modify the header of the drawing in "word" or similar to correct the reading of the file?

I have not seen any program that can edit .dwg in wordpad to make it alive again.

There was a program that can convert .plt back to .dwg but not many people use .plt anymore (but me)

 

Backup your PC often still a good practice for any offices.
