AutoBuild

AutoBuild is a Fabric mod for loading, previewing, transforming, and automatically building Minecraft schematics.

Load a .schem or .litematic file, position the ghost preview exactly where you want it, choose a building mode, and let AutoBuild place the structure while you remain in control.

AutoBuild also connects to its own community platform, where you can discover schematics, share creations, create a builder profile, and load community builds directly into the mod.
