The Autosave feature in AutoCAD does not save the drawing you are
working on, but saves a copy of your drawing to a directory stored in the
Savefilepath system variable. This drawing does not have the same name as
your drawing file and can be overwritten with subsequent Autosaves. Here's
a little VBA application which I wrote that will save your drawings at a
user determined interval. (or very close.) It basically takes the time
from the system clock and stores it in one of the User system variables.
Every time you select "Line," "Pline," or
"Zoom," the application checks to see if 15 minutes have passed.
If it hasn't, it does nothing. If it has, it saves the drawing and then
resets the stored time to the system time. (Phew!)
Stick this coding in a module, save it as "SaveMan.dvb," and
add it to your startup suitcase.

'If the time has not been set
If OldTime = 0 Then
'set the time
ThisDrawing.SetVariable ("Useri2"), NewTime
'then end
End
End If
'if the difference is greater that 15 minutes
If (NewTime - OldTime) > 15 Then
'save the drawing
ThisDrawing.Save
'and then reset Useri2
ThisDrawing.SetVariable ("Useri2"), NewTime
End If
' end of the Select
End Select
