Angle trisection in AutoCAD.

A - answer How to draw an angle trisection in AutoCAD? Let us suppose an angle represented by e.g. two intersecting lines.
  1. Switch on the osnap modes Intersection, Nearest and Node
  2. Draw a temporary arc (with center in the angle apex) representing your angle (the ARC command with Center option)
  3. Divide the arc in 3 parts using the DIVIDE command (you can display the newly created node points by setting PDMODE to e.g. 3 and performing a regen)
  4. Now you can draw lines or rays from the angle apex to the both new nodes on the arc

Bisecting an angle is much more easier - see the XLINE command.
