FOR CUTOUT OCTAGONS:
Start with a square, multiply your square's length (x) 0.29291 or 0.293 measure from square's corner out and mark at the value. Do this from all 4 corners in all directions 8 times. Line up and cut off = square to octagon.

This is your long diagonal length at 1/2 = the center.
