Not heard of directional terrain grids, please elaborate

Example:

Find a small hill. Go to the top of it and use your pickaxe to dig down in the same spot 3 or 4 times. Your 4 walls of the hole are the start of your grid. Do not dig diagonal from the hole as it will create jagged walls.

try the hoe with the pathen option - one might this useful
pathing will create more like square shapes and one can see what the "grid" is
