How to recover from a crash


In case of a crash, all unsaved changes in a drawing are lost.

That is why it is important to:

  • Save your work regularly. The easiest way to do this is using the shortcut Ctrl+S (QSAVE command). If SAVEBAK is ON, BricsCAD automatically creates a .bak file of the previous version of a drawing when saving.

  • Set the SAVETIME system variable, which specifies the interval in minutes for automatic saves of all open drawings. By default, SAVETIME is 60.

    Automatically saved drawing files have the .SV$ extension and they are saved in the folder set by the SAVEFILEPATH system variable.


You can use the .bak and .SV$ files to recover your work in case of a crash. To recover a drawing, select the .bak or .SV$ file and change its extension to .dwg.


When crashes occur repeatedly, it might help to restart BricsCAD using a fresh profile with hard-coded default settings.

Double click profilemanager_app.exe in the BricsCAD installation folder.

The User profile manager dialog box displays.

Click the Create button.

The Create profile dialog box displays.

  1. Type a name in the name field, then click the OK button.
  2. Select the new profile and click the Set Current button.
  3. Click the OK button.
  4. Restart BricsCAD.
