That would be great (sort of) if it actually worked !!
What happened to me was I was in a drawing that I had started at 10:30 AM and at 15:50 the computer shut down inexplicably before I had saved the drawing. I rebooted to see what caused the shut down and found nothing that could explain this in the event log. So I then went to the Autosave folder to recover my drawing that was set to autosave every 20 minutes. It was EMPTY. Surely when a computer shuts down inexplicably Rhino has NOT “successfully closed the parent file”and an Autosave file should be left in the folder?
I have also established that nothing is left in the Autosave folder if the system powers down with the drawing open either ?
Personally I feel that the autosave feature should be a user controlled Backup system (by preference) so that the file is regularly saved in the designated autosave folder. It would be even better if the autosave did not overwrite but added a sequence number or date/time number so these can be referred to during a drawing session. At the end of a drawing session users can then choose to delete the autosave files or keep them and only then are they put in the recycle bin.
