About
MCEdit is a versatile map editor, designed for moving blocks from one level to another. With it, you can open a level of nearly any type and fly around in glorious 3D with multiple levels of detail! Select millions of blocks and clone them anywhere else in the level. Fill a boxy selection with the block of your choice, or replace one kind of block with another. Export blocks to a "schematic" file for later use. Import a schematic or an entire level into any world using the crane. Move the player or his spawn point. Create and and remove chunks from the world. Fill blackened areas with light. Find bugs!
Remember: Control-Z to undo, Control-S to save.
Tools
Here's a quick overview of a few of the different tools we have:
Selection: Make a selection by marking its corners. Press again to switch corners. Delete blocks or entities, or export the selection to a .schematic file.
Brush: Click to fill a shaped area with blocks. Choose brush size, shape, and type of block.
Clone: Copies the selected blocks. Click to set the copy down, then press "Clone" to clone. E R F to transform blocks.
Fill: Fills the selection with a chosen block type, optionally replacing another type. R to start replacing, E to swap materials.
Crane: Import a Schematic file or an entire level. Use this to convert older levels by importing them into an Alpha world.
Player: Click to move the player. May move the player to and from the Nether. Press twice to teleport.
Spawn: Click to move the player's spawn. Not available in the Nether. Press twice to teleport.
Chunk: Create, delete, and light chunks. Prune away all of the chunks outside the selection.
