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
Object snap tracking
Finding the centre (centroid) of a square or rectangle used to require the use of at least one construction line but with object snap tracking, the same point can be found without having to draw any other objects.
This technique relies on the fact that "Midpoint" is set as one of your running object snaps and that polar tracking (POLAR) and object snap tracking (OTRACK) are on. Say you have a square and you want to draw an inscribed circle. Start the circle command and then hover the cursor over one of the vertical sides of the square until the midpoint snap icon appears. Move towards the centre and a dotted tracking like will appear. Next, hover the cursor over one of the horizontal sides of the square until the midpoint icon appears, again, move towards the centre of the square. This time, when you get close to the centre, both horizontal and vertical tracking lines appear and you can snap to the intersection simply by left-clicking. Finish the circle by snapping to any midpoint.
