DIMASO DDIM
Type: Switch
Saved in: Drawing
Initial value: On
Controls the associativity of dimension objects.
Off Creates no association between the various elements of the dimension. The lines, arcs, arrowheads, and text of a dimension are drawn as separate objects.

DIMASO is not stored in a dimension style.
DIMASSOC DDIM
Type: Integer
Saved in: Drawing
Initial value: 2
Controls the associativity of dimension objects.
0 Creates exploded dimensions. There is no association between the various elements of the dimension. The lines, arcs, arrowheads, and text of a dimension are drawn as separate objects.
1 Creates non-associative dimension objects. The elements of the dimension are formed into a single object. If the definition point on the object moves, the dimension value is updated.
2 Creates associative dimension objects. The elements of the dimension are formed into a single object, and one or more definition points of the dimension are coupled with association points on geometric objects. If the association point on the geometric object moves, the dimension location, orientation, and value is updated.
DIMASSOC is not stored in a dimension style.
Drawings saved in a format previous to AutoCAD 2002 retain the setting of the DIMASSOC system variable. When the drawing is reopened in AutoCAD 2002 or later, the dimension associativity setting is restored. If a legacy drawing is opened in AutoCAD 2002, the DIMASSOC system variable takes on the value of the legacy drawing's DIMASO system variable.
DIMASZ DDIM

Type: Single character
Saved in: Drawing
Initial value: Decimal point (“.”)
Specifies a single-character decimal separator to use when creating dimensions whose unit format is decimal.
When prompted, enter a single character at the command line. If dimension units is set to Decimal, the DIMDSEP character is used instead of the default decimal point. If DIMDSEP is set to NULL (default value, reset by entering a period), AutoCAD uses the decimal point as the dimension separator.

DIMFIT DDIM
Type: Integer
Saved in: Drawing
Initial value: 3
Obsolete. Has no effect in AutoCAD 2000 except to preserve the integrity of pre-AutoCAD 2000 scripts and AutoLISP routines. In AutoCAD 2000, DIMFIT is replaced by DIMATFIT and DIMTMOVE. Displays at the command prompt.
0 Both text and arrowheads are placed on the outside extension lines
1 Text is placed between the extension lines and arrowheads are placed on the outside
2 Arrowheads are placed between the extension lines and text is on the outside
3 Text is placed between the extension lines and places the arrowheads on the outside

DIMFRAC DDIM
Type: Integer
Saved in: Drawing
Initial value: 0
Sets the fraction format when DIMLUNIT is set to 4 (Architectural) or 5 (Fractional).
0 Horizontal
1 Diagonal
2 Not stacked (for example, 1/2)
DIMGAP DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0900
Sets the distance around the dimension text when the dimension line breaks to accommodate dimension text. Also sets the gap between annotation and a hook line created with the LEADER command. If you enter a negative DIMGAP value, AutoCAD places a box around the dimension text.
AutoCAD also uses DIMGAP as the minimum length for pieces of the dimension line. When calculating the default position for the dimension text, it positions the text inside the extension lines only if doing so breaks the dimension lines into two segments at least as long as DIMGAP. Text placed above or below the dimension line is moved inside only if there is room for the arrowheads, dimension text, and a margin between them at least as large as DIMGAP: 2 * (DIMASZ + DIMGAP).
DIMGAP also sets the gap between a tolerance symbol and its feature control frame.
DIMJUST DDIM
Type: Integer
Saved in: Drawing
Initial value: 0
Controls the horizontal positioning of dimension text.
0 Centered along the dimension line between the extension lines
1 Next to the first extension line
2 Next to the second extension line
3 Above and aligned with the first extension line
4 Above and aligned with the second extension line
DIMLDRBLK DDIM
Type: String
Saved in: Drawing
Initial value: “”
Specifies the arrow type for leaders. To turn off arrowhead display, enter a single period (.). For a list of arrowhead entries, see DIMBLK.
DIMLFAC DDIM
Type: Real
Saved in: Drawing
Initial value: 1.0000
Sets a scale factor for linear dimension measurements. All linear dimension distances, including radii, diameters, and coordinates, are multiplied by DIMLFAC before being converted to dimension text.
DIMLFAC has no effect on angular dimensions, and is not applied to the values held in DIMRND, DIMTM, or DIMTP.
If you create a dimension in paper space and DIMLFAC is not set to zero, AutoCAD multiplies the distance measured by the absolute value of DIMLFAC. In model space, negative values for DIMLFAC are ignored, and the value 1.0 is used instead.
AutoCAD computes a value for DIMLFAC if you try to change DIMLFAC from the Dim prompt while in paper space and you select the Viewport option.
Dim: dimlfac
Current value <1.0000> New value (Viewport): v
Select viewport to set scale:
AutoCAD calculates the scaling of model space to paper space and assigns the negative of this value to DIMLFAC.
DIMLIM DDIM
Type: Switch
Saved in: Drawing

DIMPOST DDIM
Type: String
Saved in: Drawing
Initial value: “”
Specifies a text prefix or suffix (or both) to the dimension measurement. For example, to establish a suffix for millimeters, set DIMPOST to mm; a distance of 19.2 units would be displayed as 19.2 mm.
If tolerances are turned on, the suffix is applied to the tolerances as well as to the main dimension.
Use <> to indicate placement of the text in relation to the dimension value. For example, enter <>mm to display a 5.0 millimeter radial dimension as “5.0mm.” If you entered mm <>, the dimension would be displayed as “mm 5.0.” Use the <> mechanism for angular dimensions.
DIMRND DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0000
Rounds all dimensioning distances to the specified value. For instance, if DIMRND is set to 0.25, all distances round to the nearest 0.25 unit. If you set DIMRND to 1.0, all distances round to the nearest integer. Note that the number of digits edited after the decimal point depends on the precision set by DIMDEC. DIMRND does not apply to angular dimensions.
DIMSAH DDIM
Type: Switch
Saved in: Drawing
Initial value: Off
Controls the display of dimension line arrowhead blocks.
Off Use arrowhead blocks set by DIMBLK
On Use arrowhead blocks set by DIMBLK1 and DIMBLK2
DIMSCALE DDIM
Type: Real
Saved in: Drawing
Initial value: 1.0000
Sets the overall scale factor applied to dimensioning variables that specify sizes, distances, or offsets. Also affects the scale of leader objects created with the LEADER command.
0.0 AutoCAD computes a reasonable default value based on the scaling between the current model space viewport and paper space. If you are in paper space or model space and not using the paper space feature, the scale factor is 1.0.
>0 AutoCAD computes a scale factor that leads text sizes, arrowhead sizes, and other scaled distances to plot at their face values.
DIMSCALE does not affect tolerances or measured lengths, coordinates, or angles.

DIMSHO DDIM
Type: Switch
Saved in: Drawing
Initial value: On
Controls redefinition of dimension objects while dragging. Associative dimensions recompute dynamically as they are dragged. On some computers, dynamic dragging can be very slow, so, set DIMSHO to off to drag the original image instead. DIMSHO is not stored in a dimension style.
Off Update off
On Update on
DIMSOXD DDIM
Type: Switch
Saved in: Drawing
Initial value: Off
Suppresses drawing of dimension lines outside the extension lines.
Off Dimension lines are not suppressed

DIMSTYLE DDIM
(Read-only)
Type: String
Saved in: Drawing
Initial value: “STANDARD”
DIMSTYLE is both a command and a system variable. The DIMSTYLE system variable shows the current dimension style. To display the DIMSTYLE system variable, use the SETVAR command. The DIMSTYLE system variable is read-only; you cannot change its value on the command line. To change the current dimension style, use the DIMSTYLE command.
DIMTAD DDIM
Type: Integer
Saved in: Drawing
Initial value: 0
Controls the vertical position of text in relation to the dimension line.
0 Centers the dimension text between the extension lines.
1 Places the dimension text above the dimension line except when the dimension line is not horizontal and text inside the extension lines is forced horizontal (DIMTIH = 1). The distance from the dimension line to the baseline of the lowest line of text is the current DIMGAP value.

Saved in: Drawing
Initial value: On
Controls the position of dimension text inside the extension lines for all dimension types except ordinate.
Off Aligns text with the dimension line
On Draws text horizontally
DIMTIX DDIM
Type: Switch
Saved in: Drawing
Initial value: Off
Draws text between extension lines.
Off Varies with the type of dimension. For linear and angular dimensions, AutoCAD places text inside the extension lines if there is sufficient room. For radius and diameter dimensions that don’t fit inside the circle or arc, DIMTIX has no effect and always forces the text outside the circle or arc.
On Draws dimension text between the extension lines even if AutoCAD ordinarily places it outside those lines.
DIMTM DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0000
Sets the minimum (or lower) tolerance limit for dimension text when DIMTOL or DIMLIM is on. AutoCAD accepts signed values for DIMTM. If DIMTOL is on and DIMTP and DIMTM are set to the same value, AutoCAD draws a tolerance value.
If DIMTM and DIMTP values differ, the upper tolerance is drawn above the lower, and a plus sign is added to the DIMTP value if it is positive.
For DIMTM, AutoCAD uses the negative of the value you enter (adding a minus sign if you specify a positive number and a plus sign if you specify a negative number).
DIMTMOVE DDIM
Type: Integer
Saved in: Drawing
Initial value: 0
Sets dimension text movement rules.
0 Moves the dimension line with dimension text

Initial value: 0.0000
Sets the maximum (or upper) tolerance limit for dimension text when DIMTOL or DIMLIM is on. AutoCAD accepts signed values for DIMTP. If DIMTOL is on and DIMTP and DIMTM are set to the same value, AutoCAD draws a tolerance value.
If DIMTM and DIMTP values differ, the upper tolerance is drawn above the lower and a plus sign is added to the DIMTP value if it is positive.
DIMTSZ DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0000
Specifies the size of oblique strokes drawn instead of arrowheads for linear, radius, and diameter dimensioning.
0 Draws arrowheads.
1 Draws oblique strokes instead of arrowheads. The size of the oblique strokes is determined by this value multiplied by the DIMSCALE value.
DIMTVP DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0000
Controls the vertical position of dimension text above or below the dimension line. AutoCAD uses the DIMTVP value when DIMTAD is off. The magnitude of the vertical offset of text is the product of the text height and DIMTVP. Setting DIMTVP to 1.0 is equivalent to setting DIMTAD to on. AutoCAD splits the dimension line to accommodate the text only if the absolute value of DIMTVP is less than 0.7.

FACETRATIO 3D/Display
Type: Integer
Not saved
Initial Value: 0
Controls the aspect ratio of faceting for cylindrical and conic ACIS solids. A setting of 1 increases the density of the mesh to improve the quality of rendered and shaded models.
0 Creates an N by 1 mesh for cylindrical and conic ACIS solids
1 Creates an N by M mesh for cylindrical and conic ACIS solids
FACETRES 3D/Display
Type: Real
Saved in: Drawing
Initial value: 0.5
Adjusts the smoothness of shaded and rendered objects and objects with hidden lines removed. Valid values are from 0.01 to 10.0 (smoothest). FACETRES controls the smoothness of shaded and rendered curved solids. It is linked to the value set by VIEWRES (a command, not a variable): when FACETRES is set to 1, there is a one-to-one correspondence between the viewing resolution of circles, arcs, and ellipses and the tessellation of solid objects. For example, when FACETRES is set to 2, the tessellation will be twice the tessellation set by VIEWRES. VIEWRES can be set from 1 to 20000 (the smoothest).
When you raise and lower the value of VIEWRES, objects controlled by both VIEWRES and FACETRES are affected. When you raise and lower the value of FACETRES, only solid objects are affected.
FILEDIA Environment
Type: Integer

1 Objects are filled
FONTALT TOOLS/OPTIONS
Type: String
Saved in: Registry
Initial value: “simplex.shx”
Specifies the alternate font to be used when the specified font file cannot be located. If an alternate font is not specified, AutoCAD displays the Alternate Font dialog box. The dialog box is displayed in the following cases:
1. A Release 13 drawing is opened; FONTALT is not set or not found; and a TrueType®, SHX, or PostScript font is not found for a defined text style.
2. A Release 14 drawing is opened, FONTALT is not set or not found, and an SHX or PostScript font is not found for a defined text style. For missing TrueType fonts in Release 14 drawings, AutoCAD automatically substitutes the closest TrueType font available.
3. The Browse button is pressed in the Options dialog box when you specify an alternate font.
AutoCAD validates the alternate font specified for FONTALT. If the font name or font file name is not found, the message “Font not found” is displayed. Enter either a TrueType font name (for example, Times New Roman Bold) or a TrueType file name (for example timebd.ttf). When a TrueType file name is entered for FONTALT, AutoCAD returns the font name in place of the file name if the font is registered with the operating system.
FONTMAP TOOLS/OPTIONS
Type: String
Saved in: Registry
Initial value: “acad.fmp”
Specifies the font mapping file to be used. A font mapping file contains one font mapping per line; the original font used in the drawing and the font to be substituted for it are separated by a semicolon (;). For example, to substitute the Times TrueType font for the Roman font, the line in the mapping file would read as follows:
romanc.shx;times.ttf
If FONTMAP does not point to a font mapping file, if the FMP file is not found, or if the font file name specified in the FMP file is not found, AutoCAD uses the font defined in the style. If the font in the style is not found, AutoCAD substitutes the font according to substitution rules.
FRONTZ DDVIEW

ISAVEBAK
TOOLS/OPTIONS Type: Integer Saved in: Registry Initial value: 1 Improves the speed of incremental saves, especially for
large drawings. ISAVEBAK controls the creation of a backup file (BAK). In
Windows, copying the file data to create a BAK file for large drawings takes a
major portion of the incremental save time. 0 No BAK file is
created (even for a full save) 1
A BAK file is created WARNING In some cases (such as a power failure in the
middle of a save), it’s possible that drawing data can be lost. ISAVEPERCENT
TOOLS/OPTIONS Type: Integer Saved in: Registry Initial value: 50 Determines the amount of wasted space tolerated in a
drawing file. The value of ISAVEPERCENT is an integer between 0 and 100. The
default value of 50 means that the estimate of wasted space within the file
does not exceed 50 percent of the total file size. Wasted space is eliminated
by periodic full saves. When the estimate exceeds 50 percent, the next save
will be a full save. This resets the wasted space estimate to 0. If
ISAVEPERCENT is set to 0, every save is a full save. 0 Minimum 100 Maximum ISOLINES

MVIEW Type: Integer Saved in: Drawing Initial value: 1 Controls paper space linetype scaling. 0 No special
linetype scaling. Linetype dash lengths are based on the drawing units of the
space (model or paper) in which the objects were created. Scaled by the global
LTSCALE factor. 1 Viewport scaling
governs linetype scaling. If TILEMODE is set to 0, dash lengths are based on
paper space drawing units, even for objects in model space. In this mode,
viewports can have varying magnifications, yet display linetypes identically.
For a specific linetype, the dash lengths of a line in a viewport are the same
as the dash lengths of a line in paper space. You can still control the dash
lengths with LTSCALE. When you change PSLTSCALE or use a command such as ZOOM
with PSLTSCALE set to 1, objects in viewports are not automatically regenerated
with the new linetype scale. Use the REGEN or REGENALL commands to update the
linetype scales in each viewport. PSPROLOG

SPLINE Type: Integer Saved in: Drawing Initial value: 8 Sets the number of line segments to be generated for each
spline-fit polyline generated by the Spline option of the PEDIT command. Valid settings range from –32768 to 32767. If you set
SPLINESEGS to a negative value, AutoCAD generates segments using the absolute
value of the setting, and then applies a fit-type curve to those segments.
Fit-type curves use arcs as the approximating segments. Using arcs yields a
smoother generated curve when few segments are specified, but the curve can
take longer to generate. SPLINETYPE

TREEDEPTH Environment
Type: Integer
Saved in: Drawing
Initial value: 3020
Specifies the maximum depth, that is, the number of times the tree-structured spatial index can divide into branches.
0 Suppresses the spatial index entirely, eliminating the performance improvements it provides in working with large drawings. This setting assures that objects are always processed in database order, making it unnecessary ever to set SORTENTS.
>0 Turns on TREEDEPTH. An integer of up to four digits is valid. The first two digits refer to model space, and the second two digits refer to paper space.
<0 Treats model space objects as 2D (Z coordinates are ignored), as is always the case with paper space objects. Such a setting is appropriate for 2D drawings and makes more efficient use of memory without loss of performance.
NOTE: You cannot use TREEDEPTH transparently.
TREEMAX Environment
Type: Integer
Saved in: Registry
Initial value: 10000000
Limits memory consumption during drawing regeneration by limiting the number of nodes in the spatial index (oct-tree).
By imposing a fixed limit with TREEMAX, you can load drawings created on systems with more memory than your system and with a larger TREEDEPTH than your system can handle. These drawings, if left unchecked, have an oct-tree large enough to eventually consume more memory than is available to your computer. TREEMAX also provides a safeguard against experimentation with inappropriately high TREEDEPTH values.
The initial default for TREEMAX is 10000000 (10 million), a value high enough to effectively disable TREEMAX as a control for TREEDEPTH. The value to which you should set TREEMAX depends on your system’s available RAM. You get about 15,000 oct-tree nodes per megabyte of RAM.
If you want an oct-tree to use up to, but no more than, 2 megabytes of RAM, set TREEMAX to 30000 (2 x 15,000). If AutoCAD runs out of memory allocating oct-tree nodes, restart AutoCAD, set TREEMAX to a smaller number, and try loading the drawing again.
AutoCAD might occasionally run into the limit you set with TREEMAX. Follow the resulting prompt instructions. Your ability to increase TREEMAX depends on your computer’s available memory.
TRIMMODE CHAMFER

Initial value: “World”
Stores the name of the UCS that defines the origin and orientation of orthographic UCS settings. Valid values include any named UCS.
UCSFOLLOW Display
Type: Integer
Saved in: Drawing (viewport specific)
Initial value: 0
Generates a plan view whenever you change from one UCS to another. Set UCSFOLLOW separately for each viewport. If UCSFOLLOW is on for a particular viewport, AutoCAD generates a plan view in that viewport whenever you change coordinate systems. Once the new UCS has been established, you can use DVIEW, PLAN, VIEW, or VPOINT to change the view of the drawing. It will change to a plan view again the next time you change coordinate systems.
0 UCS does not affect the view
1 Any UCS change causes a change to the plan view of the new UCS in the current viewport
The setting of UCSFOLLOW is maintained separately for paper space and model space and can be accessed in either, but the setting is ignored while in paper space (it is always treated as if set to 0). Although you can define a non-world UCS in paper space, the view remains in plan view to the world coordinate system.
UCSICON Display
Type: Integer
Saved in: Drawing (viewport specific)
Initial value: 3
Displays the UCS icon for the current viewport using bitcode. UCSICON is both a command and a system variable. It is the sum of the following:
0 No icon displayed
1 On; icon is displayed
2 Origin; if icon is displayed, the icon floats to the UCS origin if possible
3 On and displayed at origin.
The UCSICON command controls the visibility and placement of the UCS icon. Because entering ucsicon at the Command prompt invokes the UCSICON command, you must use the SETVAR command to access the UCSICON system variable.
UCSNAME Display

USERS1, USERS2, USERS3, USERS4, and USERS5 are used for storage and retrieval of text string data.
VIEWCTR Display
(Read-only)
Type: 3D point
Saved in: Drawing
Stores the center of view in the current viewport. Expressed as a UCS coordinate.
VIEWDIR Display
(Read-only)
Type: 3D vector
Saved in: Drawing
Stores the viewing direction in the current viewport expressed in UCS coordinates. This describes the camera point as a 3D offset from the target point.
VIEWMODE Display
(Read-only)
Type: Integer
Saved in: Drawing
Controls the View mode for the current viewport using bitcode. The value is the sum of the following:
0 Turned off.
1 Perspective view active.
2 Front clipping on.
4 Back clipping on.
8 UCS Follow mode on.
16 Front clip not at eye. If on, the front clip distance (FRONTZ) determines the front clipping plane. If off, FRONTZ is ignored, and the front clipping plane is set to pass through the camera point (vectors behind the camera are not displayed). This flag is ignored if the front clipping bit (2) is off.
VIEWSIZE Display
(Read-only)
Type: Real
Saved in: Drawing
Stores the height of the view in the current viewport. Expressed in drawing units.
VIEWTWIST DVIEW

VISRETAIN XREF
Type: Integer
Saved in: Drawing
Initial value: 1
Controls the visibility, color, linetype, lineweight, and plot styles (if PSTYLEPOLICY is set to 0) of xref-dependent layers and specifies whether nested xref path changes are saved.
0 The layer table, as stored in the reference drawing (xref) takes precedence. Changes made to xref-dependent layers in the current drawing are valid in the current session only and are not saved with the drawing. When the current drawing is reopened, the layer table is reloaded from the reference drawing and the current drawing reflects those settings. The layer settings affected are On, Off, Freeze, Thaw, Color, Ltype, LWeight, and PStyle (if PSTYLEPOLICY is set to 0). This setting also specifies that changes made to the paths of nested xrefs are for the current session only and are not saved with the drawing.
1 Xref-dependent layer changes made in the current drawing take precedence. Layer settings are saved with the current drawing’s layer table and persist from session to session. Nested xref path changes are saved with the current drawing and persist from session to session.
VSMAX Display
(Read-only)
Type: 3D point
Saved in: Drawing
Stores the upper-right corner of the current viewport’s virtual screen. Expressed as a UCS coordinate.
VSMIN Display
(Read-only)
Type: 3D point
Saved in: Drawing
Stores the lower-left corner of the current viewport’s virtual screen. Expressed as a UCS coordinate.
WHIPARC Display
Type: Integer
Saved in: Registry
Initial value: 0
Controls whether the display of circles and arcs is smooth.
0 Circles and arcs are not smooth, but rather are displayed as a series of vectors.
1 Circles and arcs are smooth, displayed as true circles and arcs.
WHIPTHREAD Display
(2000i)
Type: Integer
Saved in: Registry
Initial value: 3
Specifies how AutoCAD will use additional processors on the machine. This system variable has no effect on machines with single processors.
0 No multithreading is used
1 Regeneration only is carried out by multiple processors
2 Redraw only is carried out by multiple processors
3 Regeneration and Redraw are carried out by multiple processors
WMFBKGND EXPORT
Type: Integer
Not saved
Initial value: 1
Controls whether the background display of AutoCAD objects is transparent in other applications when these objects are output to a Windows metafile using the WMFOUT command.
Copied to the Clipboard in AutoCAD and pasted as a Windows metafile.
Dragged and dropped from AutoCAD as a Windows metafile
0 The background is transparent.
1 The background color is the same as the AutoCAD current background color.
WMFFOREGND EXPORT
(2000i)
Type: Integer
Not saved
Initial value: 0
Controls how the foreground color assignment to AutocAD objects of a WMF file or copyclip is created and displayed in other applications.
0 Foreground and background colors are swapped in order to ensure that the foreground color is darker than the background color
1 Foreground and background color are swapped in order to ensure that the foreground color is lighter than the background color
WORLDUCS Display
(Read-only)
Type: Integer
Not saved
Initial value: 1
Indicates whether the UCS is the same as the WCS.
0 UCS differs from the WCS
1 UCS matches the WCS
WORLDVIEW DVIEW
Type: Integer VPOINT
Saved in: Drawing
Initial value: 1
Determines whether input to the 3DORBIT, DVIEW, and VPOINT commands is relative to the WCS (default), the current UCS, or the UCS specified by the UCSBASE system variable.
0 UCS remains unchanged
1 UCS changes to the WCS for the duration of the DVIEW or VPOINT commands; the DVIEW and VPOINT command input is relative to the current UCS
WRITESTAT Drawing
(Read-only)
Not saved
Initial value: 1
Indicates whether a drawing file is read-only or can be written to. For developers who need to determine write status through AutoLISP.
0 Read only
1 Read and write
XCLIPFRAME XREF
Type: Integer
Saved in: Drawing
Initial value: 0
Controls the visibility of xref clipping boundaries.
0 Clipping boundary is not visible
1 Clipping boundary is visible
XEDIT REFEDIT
Type: Integer
Saved in: Drawing
Initial value: 1
Controls whether the current drawing can be edited in-place when being referenced by another drawing.
0 Can’t use in-place reference editing
1 Can use in-place reference editing
XFADECTL REFEDIT
Type: Integer
Saved in: Registry
Initial value: 50
Controls the fading intensity for references being edited in-place.
0 0 percent fading, minimum value
90 90 percent fading, maximum value
XLOADCTL XREF
Type: Integer
Saved in: Registry
Initial value: 1
Turns xref demand loading on and off and controls whether it opens the original drawing or a copy.
0 Turns off demand loading; entire drawing is loaded
1 Turns on demand loading, reference file is kept open
2 Turns on demand loading; a copy of the reference file is opened
When XLOADCTL is set to 2, the reference file copy is stored in the AutoCAD temporary files directory (defined by the OPTIONS command) or in a user-specified directory.
XLOADPATH Environment
Type: String XREF
Saved in: Registry
Initial value: “”
Creates a path for storing temporary copies of demand-loaded xref files. For more information, see XLOADCTL.
XREFCTL Environment
Type: Integer XREF
Saved in: Registry
Initial value: 0
Controls whether AutoCAD writes external reference log (XLG) files.
0 Does not write Xref log files
1 Writes Xref log files
Type: Integer XREF
Saved in: Registry
Initial value: 2
Controls the notification for updated or missing xrefs.
0 Disables xref notification
1 Enables xref notification. Notifies you that xrefs are attached to the current drawing by displaying the xref icon in the lower-right corner of the application window (the notification area of the status bar tray). When you open a drawing, alerts you to missing xrefs by displaying the xref icon with a yellow alert symbol (!).
2 Enables xref nofication and balloon messages. Displays the xref icon as in 1 above. Also displays balloon messages in the same area when xrefs are modified. The number of minutes between checking for modified xrefs is controlled by the system registry variable XNOTIFYTIME>
0 Does not write Xref log files
ZOOMFACTOR Display – Intellimouse support
Type: Interger
Saved in: Registry
Initial value: 10
Accepts an integer between 3 and 100 as valid values. The higher the number, the more incremental the change applied by each mouse-wheel’s forward/backward movement.
