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
Repeat for Efficiency
Sometimes, you may find yourself having to use the same command repeatedly. This can be a pain, unless you are aware that the previous command can always be repeated by hitting the Enter key on the keyboard or by using the right-click mouse button and selecting the name of the command you just used. Both these methods are more efficient than repeatedly finding a command on a toolbar or from a pull-down menu.
What's more annoying than having to repeat a single command (and more common) is having to repeat a sequence of maybe two or three commands. Obviously, you can't use the "Enter to repeat" trick. However, the right-click menu has another option that can help in these situations. Below the name of the last command used, is a menu option that says . If you select this option, you will see a list of all the commands used in the current drawing session, with the most recently used at the top.
Using this method, you can repeat any sequence of commands without having to return to a toolbar or pull-down menu.
Note: This function is controlled by the inputhistorymode variable.
