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
Extend/Trim commands
While in the middle of either of the Trim or Extend command, you don't have to exit out of one to start the other; they're virtually the same command. So if you're using Trim, and need to Extend, simply hold down the SHIFT key and it will convert to the Extend command, and vice-versa.
