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.

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
Shift for fillet radius zero
Do you get fed up having to set your Fillet alternately to a radius value and then to 0 to get a right angle?
You don't have to! Just fillet your lines while holding down Shift and the current default fillet radius value will be ignored.
