User Increment Angles for Polar (new in 2015)
From: AutoCAD Productivity Articles #138
Originally published: February 2015
The Polar tracking feature [F10] comes with several preset increments. But what if you want your own increment, like, 12? This is now available for the first time in AutoCAD 2015 where you can specify an increment value, and AutoCAD will snap to all instances of that increment!
How to Add Additional Polar Angles
Click the drop-down arrow beside Polar Tracking, then click Tracking Settings.
Check the box for Additional Angles, then click New and enter a new angle. Click OK to close the Drafting Settings dialog box.
Click the dropdown arrow beside Polar Tracking, then click your new angle increments.

Tip of the Day
Keeping the UCS icon in its place
By default, AutoCAD always displays the UCS icon at the drawing origin (0,0) unless the origin is off screen, in which case, the UCS icon sits quietly in the bottom left-hand corner of the drawing area.
If you find the UCS icon distracting when it's floating in the middle of the screen, you can force it to be displayed in the bottom left-hand corner using the ucsicon command.
Enter an option [ON/OFF/All/Noorigin/ORigin/Properties] <ON>:
Use the "Noorigin" option to force the icon into the bottom left corner and the "ORigin" option to set it back to the default.
See the UCS Icon tutorial for more details.
