As an aside, if you have set BricsCAD to do autosaves, it will save the file as a .SV$ in what ever directory it is set to do this. (set by SAVEFILEPATH) Whenever you close a drawing, or exit BricsCAD gracefully (i.e. no crash) it will delete any SV$ files it created for the drawing. Like a BAK file, you just need to find the SV$ file, and rename the extension to DWG to use it.
