A Better Autosave
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 has 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.
Stick this coding in a module, save it as "SaveTime.dvb," and add it to your startup suitcase.
