AutoCAD Productivity
Dual Dimensions in a Dimension Style
From: AutoCAD Productivity Articles #147
Originally published: August 2016
‘Alternate Units’ doesn't always mean Metric.
To follow along, set the current Dimension style to one you like. The following exercise begins with a Dimension Style with the Unit format set to Architectural on the Primary Units tab.
How to Display Ft′-In″ as well as Inches
Launch the Dimension Style dialog box [Alias: D], click New and enter a name, then click Continue.
Click the Alternate Units tab.
In the upper left corner, put a check in the box for Display Alternate Units.
Set the Unit Format to Fractional.
Note: I would suggest you set the values for the Precision and the Round off to the same values as those on the Primary Units tab.
Set the Multiplier for Alt Units to 1.00.
In the Suffix edit box, put the inch marks ( ″ ).

The last setting you may want to make is to set the Placement feature radio button (under the preview) to Below Primary Value.

Click OK, Close the Dimension Style dialog box, then check out your new dimension!

Tip of the Day
Shift + Right-click menu
Object snaps are really important in AutoCAD and in addition to the running object snaps, many AutoCAD users have the Object Snap toolbar permanently docked on their screen. However, as screen space is often at a premium, you might like to consider accessing the object snaps from the Shift + Right-click menu. If you didn't know about this, you'll find that it's even better than the Object Snap toolbar because it takes up no space and it contains all the object snaps including "Mid Between 2 Points" and the Point Filters.
