'''Flattening''' is the [[digging]] process of making a [[tile]] flat. A tile is considered flat when all four corners of the tile are of the same height, which can be seen by examining tile borders. If all 4 borders around a tile are reported as "level", the tile is flat.
*Corner 4: 10
But you realize that doing this was retardeda mistake, and want the tile flat again. You ''could'' just dig up the extra 5 dirt from corner 3 again and drop them on corner 1 and it would be taken care of, but instead of that you position yourself on the tile and select "flatten".

==== Flattening cave floors ====
The flatten option can also be used to flatten cave floors, but there are some differences:
* When flattening cave floors, you have to stand on the tile you are flattening. You cannot flatten from adjacent tiles.
* The flattening option will not raise corners in caves. It will mine down all corners to match the lowest one. (Needs confirmation) Confirmed: The corners are lowered.
=== Manual flattening ===
=== Summary ===
Understand that the world is made up of pillars, and that the tiles are merely thin textures stretched out from the pillar's highest points. When you dig or drop dirt, all you do is adjust the height of the pillar (ie, a corner) you are standing nearest. When digging, all that matters are the corners. Tiles only matter when you use the "flatten" command, in which case the selected tile only decides which 4 corners (or pillars) should be compared to eachother each other and adjusted. Otherwise, ''forget about the tiles, only think about the corners''. Also, never forget that when digging and dropping dirt, it doesn't matter where you click, '''only where your feet are located'''.
Using a combination of manual and automatic flattening is usually the best idea once you've gotten the hang of how the system works, but until you do you may find it easier to rely on manual flattening.
The limitations of manual flattening is, of course, that it may take more time and interaction to complete, and also is subject to dirt flow. Dirt flow is what happens when you try to drop dirt on a corner with a slope diagonally that exceeds 40 in steepness (For example: You're dropping dirt northeast, then slopes N+W or E+S shouldn't be higher then 40 together). When using the "flatten" command, dirt flow ''does not apply'' and you can use it to create extreme slopes by the use of a technique known as [[Guides/FlatRaising|flatraising]]
=== Tips ===
When flattening stand on the lowest corner. Standing on the higher ones might get you some fall damage and that stops the flattening timer to prevent you dying from it.
