I've been working with my project in AutoCAD in some months. Past several days I was finishing my .dwg project. Yesterday I almost done, but when I wanted to make last check, AutoCAD messaged: "DWG file hangs or crashes AutoCAD". I was searching dwg recover utility for some hours, but I couldn't find something worth. Now I stop my search, I'm waiting for some suggestions pats. Thanks in advance.
One method for recovering corrupt drawings is to insert the drawing into a new blank drawing. However, when you use this method your layouts are not recovered.
There are some variable methods, it were collected over the Internet, probably it might be quite effective
You can use AutoCAD DesignCenter to copy layout information that otherwise would be lost.
After inserting the corrupt drawing in AutoCAD 2000, save the new drawing with the inserted objects.
Select Tools > AutoCAD DesignCenter, then select the Desktop icon.
In the DesignCenter tree view, navigate to the corrupt file and select it.
Click the plus sign (+) in the box to the left of the drawing icon and select Layout Below.
If the drawing is not overly corrupted, the existing layout(s) will display in the contents of the DesignCenter window.
Select the layout(s) and drag them into the current drawing.
To remove a layout right-click on it at the bottom of the AutoCAD editing window and selecting Delete.
You can also use this procedure to restore External References lost as a result of file corruption.
Important: Run the AUDIT command after adding each layout, in case the newly inserted layout was originally the cause of the corrupt drawing. Also, save your drawing after each AUDIT command so that if one layout does corrupt the drawing, your losses will be minimal.
