Instant Blueprint Builder

Quickstart

1. Get an Instant Blueprint Builder: craft one using the recipe below, or find it in Creative mode’s Tools & Utilities tab.
2. Hold it and sneak-use a block at one corner of a small build. Then use it normally on the block at the opposite corner to capture the blueprint.
3. To build a copy, use the builder on the face of a block where you want the copy to start. The blueprint begins in the space just beyond that face.
4. In Survival, keep the required blocks in your inventory. In Creative, building is free.

The two capture corners must be in the same dimension. Each side can be at most 16 blocks long, and a capture can contain up to 2,048 supported blocks.

Overview

The builder stores one blueprint on the item itself. Capturing another build replaces the stored blueprint. Capturing does not remove blocks from the original build.

The captured area is a cuboid between the two clicked blocks. Air is skipped, so empty spaces in the cuboid are not copied or cleared at the destination. Block entities—such as chests and their contents—aren’t captured.

What It Adds

• Instant Blueprint Builder: A single-stack tool for capturing and placing small builds.

How To Use

Capture a blueprint

1. Sneak-use the builder on the first corner block.
2. Use it normally on the opposite corner block.

The corner order doesn’t matter. The builder captures supported, non-air blocks between them. If the area is too large or contains no supported blocks, the capture won’t complete. Sneak-use the builder on a block to start over; this also replaces any blueprint already stored on the tool.

Place a blueprint

Use the builder on the face of a block next to the desired starting space. The block at the capture’s minimum X, Y, and Z position goes into the space beside the clicked face. Other blocks keep their captured offsets along the world’s X, Y, and Z axes: the blueprint does not rotate to match the face.

The destination must be within the loaded area and clear of blocks that cannot be replaced. In Survival, the builder checks your inventory for the needed blocks before placing; blocks already matching the blueprint don’t need to be supplied. In Creative, no materials are consumed.

Crafting And Obtaining

Craft the builder with this recipe:

It is also available in Creative mode’s Tools & Utilities tab.

Abilities And Mechanics

• Captured block states, including properties such as facing, are used when placing the blueprint.
• Air and blocks with block entities are skipped during capture.
• Each cuboid side is limited to 16 blocks; no more than 2,048 supported blocks can be captured.
• A blueprint can be placed in a different dimension from the one where it was captured.

Progression And Strategy

Capture a build with its minimum X/Y/Z corner in the orientation you want to reuse. Because placement preserves world-axis offsets rather than rotating the structure, plan the captured orientation before copying it. Keep a spare builder if you want to preserve one blueprint while capturing another.
