Getting around
First, let's figure out how you can get around quickly.
  1. Look at a block not too far away and type /jumpto
  2. Stand under a tree and type /ascend
  3. While on top of the tree, type /descend
  4. Stand behind a tree trunk, look straight ahead, make sure there's room on the other side, and type /thru
Making selections
A cuboid is like 3D rectangle. In WorldEdit, you select the region that you want by setting two points of a cuboid.

How do you choose the two points?
  • Left and right click blocks while holding a wooden axe (use //wand to get a wooden axe)
  • Stand somewhere and type //pos1 and //pos2
  • Look at a block and type //hpos1 and //hpos2
Tutorial: Make an approximate selection of a 15x15x15 area to test with and go to the next section.

Want to see selection lines?
To see lines that show what you have selected, then you need to install WorldEditCUI, a mod by Mumfrey, on your client. Note that WorldEditCUI uses LiteLoader so you need to install that.

Doing things with the selection
  1. Set the entire thing to bedrock: //set minecraft:bedrock
  2. Set the entire thing to brick: //set brick (here we are using WorldEdit's internal block names)
  3. Set the selection to 50% sandstone, 50% glass: //set sandstone,glass
  4. Replace the sandstone with dirt: //replace sandstone dirt
  5. Clear the area: //set 0
  6. Generate an interesting shape: //g wool data=(32+15/2/pi*atan2(x,y))%16; (0.75-sqrt(x^2+y^2))^2+z^2 < 0.25^2
  7. Look in a cardinal direction (not diagonal) and repeat your selection: //stack 4
Let's undo your changes!
  1. Undo 7 times: //undo 7
  2. Undo once: //undo
Adjusting the selection
So you've got a cuboid. Let's change it!
  1. Make the cuboid 10 blocks taller, going up: //expand 10 up
  2. Make the cuboid 5 blocks longer in the direction that you are looking: //expand 5
  3. Make the cuboid 10 blocks shorter, going down: //contract 10 down
Playing with brushes
  1. Grab a pickaxe (try diamond) and have it as your active slot.
  2. Turn on a stone brush of radius 5: /br sphere stone 5
  3. Aim at ground not near you and right click to place large stone spheres.
  4. Make it so the brush only affects grass: /mask grass
  5. Instead of placing stone, let's place wool: /mat wool:red,wool:green
  6. Right click more areas.
  7. Disable the brush: /none
