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
Clear that 3D clutter with Orbit
When 3D drawings get complicated, it may become difficult to view a particular object in your drawing because it's being crowded by other objects. Here's a neat trick that will help you solve this problem.
Select the object or objects you're interested in before starting the Orbit (3DORBIT) command. When you start the Orbit command, all the other objects in the drawing will become invisible and your selected object can be seen alone. The other objects become visible again as soon as you exit from Orbit.
This technique can also be used to ensure that the selected object always appears in the center of the scene when orbiting. It is also possible to select the center point of rotation without having the other objects disappear - use the 3DORBITCTR command.
