AutoCAD Productivity
Avoid Using ‘Standard’ in Text & Dimension Styles
From: AutoCAD Productivity Articles #141
Originally published: August 2015
In addition to Layer 0, every single drawing on the planet has a Text style called ‘Standard’, and a Dimension style called ‘Standard’. They're the defaults.
When developing company standards, it's best to not modify the Standard styles; leave 'em alone and make your own.
And here's why. Let's say you have text you added to Drawing A (using your modified ‘Standard’ text style to use the Trebuchet font), and you drag that text into Drawing B where the Standard text style uses the TXT.SHX font.
Since Drawing B already has a ‘Standard’ text style—see opening sentence, above—who do you think will "win" when it comes to how the text looks? The text in Drawing B will use the font which is already assigned to the Standard text style.

In the illustration, you see the result when I drag the text from Drawing A into Drawing B. Questions?

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.
