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.

Preview

Features

Load and Preview Schematics

• Load .schem and .litematic files
• Preview structures using transparent ghost blocks
• Move previews in every direction
• Raise and lower the preview
• Rotate structures
• Flip previews across the X or Z axis
• Move the preview directly to your position
• Adjust preview transparency
• Hide selected blocks using block filters

Flexible Building Modes

Choose how AutoBuild places your structure:

• Per Block — Places a configurable number of blocks per tick
• Per Layer — Builds the structure layer by layer
• Instant — Places the complete structure immediately

You can also:

• Pause, resume, stop, or unload a build
• Keep or hide the preview after pausing or stopping
• Enable or disable block-placement sounds
• Undo recent building steps or the complete build history
• Adjust the building speed

Survival-Friendly Building

AutoBuild is designed for Survival projects as well as Creative building.

• Uses materials from your inventory
• Shows all materials required for a structure
• Reports which materials are missing
• Can collect materials from nearby chests, trapped chests, and barrels
• Includes a configurable container search radius
• Offers an optional safety check to prevent replacing existing blocks
• Allows Creative players to receive missing materials instantly

Community Schematic Library

AutoBuild connects directly to the AutoBuild community platform.

• Browse public schematics
• Link your website account to the mod
• Load community builds directly in-game
• Upload and publish your own schematics
• Add screenshots, categories, and visibility settings
• Create a public builder profile
• Track downloads and AutoBuild loads
• Discover builds shared by other creators

Find a build → Load it into AutoBuild → Position the preview → Start building

Export Your Own Schematics

Use the included Selection Tool to select two corners in your world and export the selected structure as a schematic.

Keep exported structures locally or publish them on your AutoBuild profile to share them through the community library.
