Using Alternate Units
Alternate Units allow you to show mixed Imperial and metric units within a single annotation.
You can do this either to the right of the base dimension or below it. Just select one of the
dimension strings and open its type properties. The Alternate Units settings are highlighted in
Figure 18.41. Set Alternate Units to Below to show the alternate units below the dimension string.
