Sets the format and precision of primary dimension units and sets prefixes and suffixes for dimension text.
The following options are displayed.
Sets the format and precision for linear dimensions.
Displays and sets the number of decimal places in the dimension text. (DIMDEC system variable)
Sets the format for fractions. (DIMFRAC system variable)
Sets the separator for decimal formats. (DIMDSEP system variable)
Sets rounding rules for dimension measurements for all dimension types except Angular. If you enter a value of 0.25, all distances are rounded to the nearest 0.25 unit. If you enter a value of 1.0, all dimension distances are rounded to the nearest integer. The number of digits displayed after the decimal point depends on the Precision setting. (DIMRND system variable)
Includes a prefix in the dimension text. You can enter text or use control codes to display special symbols. For example, entering the control code %%c displays the diameter symbol. When you enter a prefix, it overrides any default prefixes such as those used in diameter and radius dimensioning. (DIMPOST system variable)
If you specify tolerances, the prefix is added to the tolerances as well as to the main dimension.
For more information, see Control Codes and Special Characters.
Includes a suffix in the dimension text. You can enter text or use control codes to display special symbols. For example, entering the text mm results in dimension text similar to that shown in the illustration. When you enter a suffix, it overrides any default suffixes. (DIMPOST system variable)
If you specify tolerances, the suffix is added to the tolerances as well as to the main dimension.

Defines linear scale options. Applies primarily to legacy drawings.
Scale Factor: Sets a scale factor for linear dimension measurements. It is recommended that you do not change this value from the default value of 1.00. For example, if you enter 2, the dimension for a 1-inch line is displayed as two inches. The value does not apply to angular dimensions and is not applied to rounding values or to plus or minus tolerance values. (DIMLFAC system variable)
Apply to Layout Dimensions Only: Applies the measurement scale factor only to dimensions created in layout viewports. Except when using nonassociative dimensions, this setting should remain unchecked. (DIMLFAC system variable)
Controls the suppression of leading and trailing zeros and of feet and inches that have a value of zero. (DIMZIN system variable)
Zero suppression settings also affect real-to-string conversions performed by the AutoLISP® rtos and angtos functions.
Leading: Suppresses leading zeros in all decimal dimensions. For example, 0.5000 becomes .5000. Select leading to enable display of dimension distances less than one unit in sub units.
Sub-units factor: Sets the number of sub units to a unit. It is used to calculate the dimension distance in a sub unit when the distance is less than one unit. For example, enter 100 if the suffix is m and the sub-unit suffix is to display in cm.
Sub-unit suffix: Includes a suffix to the dimension value sub unit. You can enter text or use control codes to display special symbols. For example, enter cm for .96m to display as 96cm.
Trailing: Suppresses trailing zeros in all decimal dimensions. For example, 12.5000 becomes 12.5, and 30.0000 becomes 30.
0 Feet: Suppresses the feet portion of a feet-and-inches dimension when the distance is less than one foot. For example, 0'-6 1/2" becomes 6 1/2".
0 Inches: Suppresses the inches portion of a feet-and-inches dimension when the distance is an integral number of feet. For example, 1'-0" becomes 1'.
Controls the suppression of leading and trailing zeros. (DIMAZIN system variable)
