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
Do you want to turn it into one? <Y>
When using PEDIT and selecting an object which is not a polyline you will get a message asking if you want to turn it into a polyline. This can be quite annoying if you're having to create closed polylines from a bunch of lines. To stop getting this message, type PEDITACCEPT and press Enter. Then type 1 and press Enter. This will automatically answer "yes" to the question in future.
