WorldEdit & FAWE: Building & Schematics Guide

WorldEdit is the primary tool for in-game terraforming, building, and structure manipulation. For high-volume edits on 4GB RAM servers, FAWE (FastAsyncWorldEdit) is strongly recommended to prevent memory freeze crashes.

WorldEdit vs. FAWE

• Standard WorldEdit: Edits blocks synchronously. Performing large edits (e.g. //set stone across 50,000 blocks) can lock the main server thread, causing player timeouts or Out of Memory crashes.
• FastAsyncWorldEdit (FAWE): Dispatches block updates asynchronously in the background. It protects server TPS and caps maximum block operations to prevent server crashes.

Basic Selection & Wand

1. Run //wand to receive the wooden axe selection wand.
2. Left-click a block to define Position 1.
3. Right-click a block to define Position 2.
4. The cuboid region between those two points is now selected.

Working with Schematics

To import builds downloaded from PlanetMinecraft or build databases:

1. Upload your .schem or .schematic file to plugins/FastAsyncWorldEdit/schematics/ (or plugins/WorldEdit/schematics/).
2. In-game, load the schematic:

//schem load filename

1. Stand at your target location and run:

//paste
