How to restore a drawing from a backup file

Applicable Products : IJCAD 2013 or later

If you edit the IJCAD in DWG / DXF file you save, one before the state will remain as extension .bak files. Drawings restore from this .bak file, change the extension of BAK files in DWG in Windows Explorer.


  1. In Windows Explorer, the file extension will search the backup file .bak.
    (Usually located in the same folder as the drawing file.)
  2. Right-click the file and select Rename.
  3. Enter a new name. Use the .dwg as a file extension. (Since you can not change and there is a file with the same name in the folder, and a name that does not suffer.)
    Ex. A3 drawing.bak → A3 drawings.dwg
  4. In the same way as any other drawing file and open the file.
