AutoBuild

AutoBuild is a Fabric mod that lets you load schematics, preview them in-game, and build them automatically block by block in your world.

It is made for survival builders, creative builders, multiplayer servers, and content creators who want faster building without losing control over placement, rotation, preview, and materials.
