OS Land Grader

Four markers, one square, and a blade that grades the ground to match.

Set it by dragging

Put the markers out and drag each one up or down to set that corner's height. Drag one sideways and the whole square follows it - it stays square rather than stretching into a rectangle. The hovertext shows all four heights and the fall between them, so you can read the grade before you commit to it. Level All snaps every corner to the same height when you just want flat.

Watch it work

Grade, and a blade is rezzed at one edge spanning the square. It sweeps across, terraforming the strip beneath it as it passes and riding at the height it is cutting. A 32m square takes about six seconds. The ground settles as it goes, so you see the shape appear rather than one jump at the end.

Flat, sloped, or neither

All four corners level gives level ground. Two matching pairs give an even slope. Four different heights give a properly warped surface - one corner dipping while the opposite one rises.

Before you use it

There is no undo. Every height it writes replaces one that is gone, so check your corners before confirming. The region also has to allow terraforming from scripts for the object's owner.
