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
Absolute and Relative Coordinates
| Coordinate | Interpretation |
|---|---|
| 25,75 | depends on context |
| @25,75 | relative |
| #25,75 | absolute |
It used to be very simple. Enter a coordinate and AutoCAD interpreted it as an absolute coordinate. Enter a coordinate preceded by "@" (the at sign) and AutoCAD interpreted it as a relative coordinate. This simple rule changed when dynamic input was introduced and now the interpretation of coordinates is contextual. For example, when you draw a rectangle using RECTANG, the coordinate for the second point is interpreted as absolute with dynamic input turned off and as relative with dynamic input turned on. Really, try it and see.
Fortunately, there's a new coordinate prefix that forces an absolute coordinate, even when AutoCAD decides you want a relative one. Precede any coordinate with "#" (the hash sign) to force an absolute coordinate.
