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
AutoCAD 2007 - Where's my old XREF Manager?
A lot of people using AutoCAD 2007 and above don't like the new XREF Manager, so here's a simple way to get the old one back.
AutoCAD 2007 introduced a new way to manage XREFs and to bring up the "old" XREF Manager, you have to type CLASSICXREF at the command line. Well, if you want things back the way they were and use the classic XREF Manager as the default from the keyboard and from the menu, a few adjustments will get you there…
First, go to . This command opens the ACAD.PGP file in Notepad. This is where all the keyboard shortcuts are defined.
Next, scroll down until you see XR (or use ), change the value from *XREF to *CLASSICXREF and save (). Close Notepad and return to AutoCAD. Enter the command REINIT, check the "PGP File" checkbox and click "OK". That fixes the keyboard so that next time you type XR, you'll see the old manager and not the new one.
To change your Menu, type CUI at the command line. In the "Customizations in All CUI Files" pane of the "Custom User Interface" dialogue, go to and click on it once to highlight it.
Now, in the "Properties" pane, change the "Macro" setting from ^C^C_externalreferences to ^C^C_classicxref, click "OK" to save the changes and you're done.
