The figures below illustrate 12 point facing.
Figure 1 is the current case of six point facing. The front, side, rear facing is all too familiar.
Figure 2 is the same unit but is aligned along a hex row rather than a hex spine. The difference is that the target aspect is now marked along the hex row, conveniently using the hex center dots to form the line.
Figure 3 is the two images overlaid. Notice there are surprisingly few differences. Certainly not the huge different that vehicle bypass makes for facing.
