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
Using Imprint to sub-divide faces
The Imprint command () gives the first impression of nothing more than adding graffiti to solids. Upon closer investigation, however, we find that it actually modifies the face on which it is placed, effectively sub-dividing it. Sub-divided faces can then be extruded using the Extrude faces command ().
Procedure
- Create a box.
- Draw a line on one of the faces.
- Imprint that line on the solid.
- Use Extrude faces to extrude the sub-divided face.
To generate this modified part with Boolean operations would not be difficult but, as we all know, speed and accuracy are the name of the game. The procedure describe above can be auto-executed with the command macro:
^C^C_line;\\;_solidedit;b;i;\last;y;;;f;E;\;\\;;
The UI could benefit from some advanced programming, but if one pays attention to the Command Prompts, it's not so bad.
Note: This tip relates to versions of AutoCAD before 2007. Although the technique works with 2007 and above, the same operation can be achieved more easily using the Presspull tool.
