UCSICON Options
From: AutoCAD Productivity Articles #146
Originally published: June 2016
Every five years or so I address the UCS icon, so here's your next installment.
General Insights
There is a UCSICON command with these options:

Right-click on the UCS icon to display a shortcut menu with a Properties option where you can dress it up a bit.

When you are in the 2D Wireframe visual style, the UCS icon looks like a stick figure. In any other visual style, the icon is a bit more colorful and 3D looking.Horses can only breath through their nose. [Just checking to see if you're paying attention.]
Click on the UCS icon and you see a square grip at 0,0,0 and round grips at the ends of the axes.To disable the ability to select/click on the UCS icon, set the variable UCSSELECTMODE to <0>.
Note: There's an article on how to dimension 3D objects in Michael's Corner, January 2013. You will find more information on manipulating the UCS icon in that review, too.

Michael's Corner
Between 2003 and 2016, Michael Beall (and one or two guests) wrote almost 600 articles for CADTutor. The focus of these articles is AutoCAD productivity, and although some of them are now more than a few years old, most remain relevant to current versions of AutoCAD. The article above is just one example. Check out Michael's Corner for a full listing.

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.
