Initial value: “”

Specifies a text prefix or suffix (or both) to the alternate dimension measurement for all types of dimensions except angular.

For instance, if the current units are Architectural, DIMALT is on, DIMALTF is 25.4 (the number of millimeters per inch), DIMALTD is 2, and DIMAPOST is set to “mm,” a distance of 10 units would be displayed as 10”[254.00mm].

To turn off an established prefix or suffix (or both), set it to a single period (.).

DIMASO

Affected Commands: DDIM

Type: Switch

Saved in: Drawing

Initial value: On

Controls the associativity of dimension objects. Also see DIMASSOC.

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.

On - Creates an association between the elements of the dimension. The elements are formed into a single object. If the definition point on the object moves, the dimension value is updated.

DIMASO is not stored in a dimension style.

DIMASSOC

Affected Commands: DDIM

Type: Integer

Saved in: Drawing

Initial value: 2

This variable is complicated in that it functions (or doesn’t function) differently when opening pre-2002 drawings. When opening pre-2002 drawings, DIMASSOC is not utilized: AutoCAD uses the current setting of DIMASO in the drawing (as if DIMASSOC is set to 1 or 0 – DIMASO ON or OFF.) When opening a 2002 drawing in 2000i or earlier, the value of DIMASSOC is stored, and then restored when the drawing comes back in 2002. DIMASSOC replaces the DIMASO variable used in earlier versions although it is backwards compatible.

0 - There is no association between objects and their dimensions, and AutoCAD’s dimensioning commands do not fully recognize Model Space objects from Paper Space objects. Also, each dimension is a collection of individual objects – lines, arcs, text and so on.

1 - There is no association between objects and their dimensions. However, the components of each dimension are interrelated and comprise a singe AutoCAD object. If you stretch a dimension line, for example, the dimension value changes to reflect the new dimension line’s length. While AutoCAD’s dimensioning commands do recognize Model Space objects in Paper Space, they do not compensate for viewport zoom levels. Thus, the dimension values for objects in a viewport having a zoom level of 0.5XP will be one half the correct value.

2 - Objects are associated with their dimensions. Therefore, if you modify the length of a line or the radius of an arc, the dimension components and the dimension value automatically update to match the modification. Also, AutoCAD’s dimensioning commands fully recognize Model Space objects from Paper space and they automatically compensate for differences in viewport zoom levels to assign correct values to dimensions.

DIMASZ

Affected Commands: DDIM

Type: Real

Saved in: Drawing

Initial value: 0.1800

Controls the size of dimension line and leader line arrowheads. Also controls the size of hook lines. Multiples of the arrowhead size determine whether dimension lines and text should fit between the extension lines. DIMASZ is also used to scale arrowhead blocks if set by DIMBLK. DIMASZ has no effect when DIMTSZ is other than zero.

DIMATFIT

Affected Commands: DDIM

Type: Integer Saved in: Drawing

Initial value: 3

Determines how dimension text and arrows are arranged when space is not sufficient to place both within the extension lines.

0 - Places both text and arrows outside extension lines

1 - Moves arrows first, then text

2 - Moves text first, then arrows

3 - Moves either text or arrows, whichever fits best

AutoCAD adds a leader to moved dimension text when DIMTMOVE is set to 1.

DIMAUNIT

Affected Commands: DDIM

Type: Integer Saved in: Drawing

Initial value: 0

Sets the units format for angular dimensions.

0 - Decimal degrees

1 - Degrees/minutes/seconds

Affected Commands: DDIM

Type: Integer Saved in: Drawing

Initial value: 0

Suppresses zeros for angular dimensions.

0 - Displays all leading and trailing zeros

DIMGAP

Affected Commands: 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

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

Affected Commands: 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

Affected Commands: DDIM

DIMPOST

Affected Commands: 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

Affected Commands: 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.

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 lways 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

Affected Commands: 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

Affected Commands: DDIM
