Sets the format and precision of primary dimension units and sets prefixes and suffixes for dimension text.

Linear Dimensions
Sets the format and precision for linear dimensions.

Unit Format
Sets the current units format for all dimension types except Angular. (DIMLUNIT system variable)

The relative sizes of numbers in stacked fractions are based on the DIMTFAC system variable (in the same way that tolerance values use this system variable).

Precision
Displays and sets the number of decimal places in the dimension text. (DIMDEC system variable)

Fraction Format
Sets the format for fractions. (DIMFRAC system variable)

Decimal Separator
Sets the separator for decimal formats. (DIMDSEP system variable)

Round Off
Sets nearest rounding value for dimension measurements for all dimension types except Angular. (DIMRND system variable)

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. Take note that the number of digits displayed after the decimal point depends on the Precision setting.

Prefix
Includes a prefix that you specify in the dimension text. (DIMPOST system variable)

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.

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.

Suffix
Includes a suffix that you specify in the dimension text. (DIMPOST system variable)

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.


If you specify tolerances, the suffix is added to the tolerances as well as to the main dimension.

For more information, see Control Codes and Special Characters.
