Here's a quick way: 1. Create a square, centered at the origin. 2. Create another square, also centered at the origin, but under "Rotation Angle," enter 45 (for its rotation in degrees). 3. Under Booleans and Partitions, choose Intersection and create the intersection of these two squares.
And now you have an octagon. Easy! You can extrude it, if you want a 3D structure.

And here's yet another quick way! 1. Create a unit (that's the default) square, centered at the origin. 2. Choose Chamfer, and select all four corners. 3. Under "Distance from vertex, enter 1-1/sqrt(2). Click "build selected." And now you have an octagon. Easy!
