528 | Chapter 20 Dimensions and Tolerances
These settings are available on the Primary Units tab of the Dimension Style
Manager.
Control the Display of Alternate Units
You can create dimensions in two systems of measurement simultaneously.
A common use of this feature is to add feet and inches dimensions to draw-
ings created using metric units. The alternate units appear in square brackets
([ ]) in the dimension text. Alternate units cannot be applied to angular
dimensions.
If alternate units dimensioning is on when you edit a linear dimension, the
measurement is multiplied by an alternate scale value that you specify. This
value represents the number of alternate units per current unit of measure-
ment. The default value for imperial units is 25.4, which is the number of
millimeters per inch. The default value for metric units is 0.0394, which is
the number of inches per millimeter. The number of decimal places is speci-
fied by the precision value for alternate units.
For example, for imperial units, if the alternate scale setting is the default
value, 25.4, and the alternate precision is 0.00, the dimension might look like
the following figure.
