84 | Chapter 7 Start and Save a Drawing
Use Backup Files
If you turn on automatic backups, AutoCAD saves the previous version of
your drawing files to a file with the same name and a .bak file extension. To
recover the previous version of your drawing from a backup file, rename the
file using a .dwg extension.
Save Part of a Drawing File
If you want to create a new drawing file from part of an existing drawing, you
can use
BLOCK or WBLOCK. With either command, you can select objects or
specify a block definition in your current drawing and save them in a new
drawing file. You can also save a description along with the new drawing.
Save to a Different Type of Drawing File
You can save a drawing to an earlier version of the DWG or DXF format or
save a drawing as a template file. Choose the format from Files of Type in the
Save Drawing As dialog box.
Reduce the Time Required to Save a Drawing File
You can reduce the time required to save a drawing file if you specify incre-
mental saves rather than full saves. An incremental save updates only those
portions of the saved drawing file that you changed.
When you use incremental saves, drawing files will contain a percentage of
potentially wasted space. This percentage increases after each incremental
save until it reaches a specified maximum, at which time a full save is per-
formed instead. You can set the incremental save percentage in the Open and
Save tab of the Options dialog box or by setting the value of the system vari-
able
ISAVEPERCENT. If you set the value of ISAVEPERCENT to 0, all saves are full
saves.
To reduce the size of drawing files, it is recommended that you perform a full
save (with
IPERCENTSAVE set to 0) before transmitting or archiving a drawing.

To save a drawing
1 On the File menu, click Save.
If you previously saved and named the drawing, AutoCAD saves any sub-
sequent changes and redisplays the Command prompt. If you have never
saved the drawing, the Save Drawing As dialog box is displayed.
