Annotative objects may have multiple . Annotative objects are decomposed
and scale representations are saved to separate layers, which are named based
on their original layer and appended with a number.
NOTE Enabling Maintain Visual Fidelity for Annotative Objects only impacts
drawings saved to a legacy drawing file format (AutoCAD LT 2007 and earlier).
Maintain Drawing Size Compatibility
Controls large object size limit support when you open and save drawings.
(LARGEOBJECTSUPPORT on page 1561 system variable)
Thumbnail Preview Settings
Displays the Thumbnail Preview Settings dialog box, which controls whether
thumbnail previews are updated when the drawing is saved.
Incremental Save Percentage
Sets the percentage of potentially wasted space in a drawing file. Full saves
eliminate wasted space. Incremental saves are faster, but they increase the size
of the drawing.
(ISAVEPERCENT system variable)
If you set Incremental Save Percentage to 0, every save is a full save. For
optimum performance, set the value to 50. If hard disk space becomes an
issue, set the value to 25. If you set the value to 20 or less, performance of the
SAVE and SAVEAS commands slows significantly.
File Safety Precautions
Assists in avoiding data loss and in detecting errors.
Automatic Save
Saves your drawing automatically at the intervals you specify. You can specify
the location of all Autosave files by using the SAVEFILEPATH system
variable.SAVEFILE (read-only) stores the name of the Autosave file.
Minutes Between Saves: When Automatic Save is on, specifies how often the
drawing is saved.
(SAVETIME system variable)
Create Backup Copy with Each Save
Improves the speed of incremental saves, especially for large drawings.
(ISAVEBAK system variable)
For information about using backup files, see Create and Restore Backup Files
in the User's Guide.
