WorldEdit
An in-game map editing tool for changing large areas of blocks at once with selections, commands, brushes and schematics.
WorldEdit is an in-game world editor developed by EngineHub. It lets you select an area and change thousands of blocks at once instead of placing them one by one. It is available for Bukkit-based servers such as Paper and as a mod for Fabric and NeoForge/Forge.
The basics
//wandgives you the selection tool (a wooden axe by default). Left-click sets the first corner, right-click the second.//set stonefills the selection with a block.//replace dirt grass_blockswaps one block type for another inside the selection.//copy,//pasteand//rotateduplicate structures.//undoreverts your last change.
WorldEdit can also save selections as schematic files and load them later, which is how builders move structures between worlds and servers.
Why it matters for server owners
WorldEdit is standard equipment for building spawns, lobbies and event maps. It is also powerful enough to wreck a world in seconds, so access has to be controlled. Give its permissions only to trusted builders through a permissions plugin like LuckPerms, not to all players.
Large edits run on the main thread and can freeze the server for a moment. Changing millions of blocks at once will show up as a spike in MSPT and lag for everyone online.

Practical tip
Before a large edit, take a backup and test on a copy of the world if possible. //undo only works within your session history, and a server restart or crash in the middle of an edit can leave a half-changed area behind.
