relate to opening and saving files.
List of Options
following options are displayed.
Controls settings related
to saving a file.
Displays the valid file formats used when saving
a file with SAVE, SAVEAS, QSAVE, SHAREWITHSEEK and WBLOCK. The file format
selected for this option becomes the default format for saving drawings.
2004 is the drawing file format used by the AutoCAD 2004, AutoCAD
2005, and AutoCAD 2006 releases. AutoCAD 2007 is the file format
used by AutoCAD 2007, AutoCAD 2008, and AutoCAD 2009 releases.
- Maintain Visual Fidelity for Annotative Objects
Controls whether the
drawing is saved with visual fidelity.
Annotative objects may
have multiple scale
representations. Annotative objects
are decomposed and scale representations are saved to separate layers,
which are named based on their original layer and appended with
Visual Fidelity for Annotative Objects only impacts drawings saved
to a legacy drawing file format (AutoCAD 2007 and earlier).
- Maintain Drawing Size Compatibility
Controls large object
size limit support when you open and save drawings.
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.
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.
save is disabled when the Block Editor
Minutes Between Saves: When
Automatic Save is on, specifies how often the drawing is saved.
(SAVETIME system variable)
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
whether a cyclic redundancy check (CRC) should be performed each
time an object is read into the drawing. CRC is an error-checking
mechanism. If your drawings are being corrupted and you suspect
a hardware problem or a software error, turn this option on.
- Maintain a Log File
Extension for Temporary Files
Specifies a unique extension for temporary save
files. The default extension is .ac$.
Provides options for a digital signature and
password that are invoked when you save a file.
Digital Signature Information
Presents digital signature information when
a file with a valid digital signature is opened. (SIGWARN system
Controls settings that
relate to recently used files and open files.
of Recently Used Files
Controls the number of recently used files that
are listed in the File menu for quick access. Valid values are 0
Full Path In Title
Displays the full path of the active drawing
in the drawing's title bar, or in the application window title bar
if the drawing is maximized.
- Number of Recently Used Files
Controls the number of
recently used files listed in the application menu’s Recent Documents
quick menu. Valid values are 0 to 50.
External References (Xrefs)
Controls the settings
that relate to editing and loading external references.
Turns xref demand-loading
on and off, and controls whether it opens the referenced drawing
or a copy.
(XLOADCTL system variable)
- Disabled: Turns off demand loading.
- Enabled: Turns on demand loading
and improves performance. Select the Enabled setting to enhance the
loading process when working with clipped xrefs that contain a spatial
or layer index. When this option is selected, other users cannot
edit the file while it is being referenced.
- Enabled with Copy: Turns on demand
loading but uses a copy of the referenced drawing. Other users can
edit the original drawing.
Changes to Xref Layers
Controls the properties
of xref-dependent layers.
(VISRETAIN system variable)
Other Users to Refedit Current Drawing
Controls whether the
current drawing can be edited in-place when being referenced by
(XEDIT system variable)
settings that relate to AutoCAD Runtime Extension applications and
Load ObjectARX Apps
Specifies if and when
to demand-load certain applications.
(DEMANDLOAD system variable)
- Disable Load on Demand: Turns
- Custom Object Detect: Demand-loads
the source application when you open a drawing that contains custom
objects. This setting does not demand-load the application when
you invoke one of the application's commands.
- Command Invoke: Demand-loads
the source application when you invoke one of the application's commands.
This setting does not demand-load the application when you open
a drawing that contains custom objects.
- Object Detect and Command
Invoke: Demand-loads the source application when you
open a drawing that contains custom objects or when you invoke one
of the application's commands.
Images for Custom Objects
Controls the display
of proxy objects in a drawing.
(PROXYSHOW system variable)
Proxy Information Dialog Box
Displays a notice when
a proxy is created.
(PROXYNOTICE system variable)
