Blockfill Architect
Quickstart
- Craft a Filler at a crafting table:


- Hold the Filler and use it on a block while sneaking to sample that block as the fill material. By default, the material is stone.
- Use the Filler without targeting a block to open Filler Settings. Choose a surface—Floor, Roof, Walls, or Full shell—and save.
- Use the Filler on a block to mark the first corner, then use it on the opposite corner to build the selected surface between them.
Overview
The Filler builds block surfaces across a rectangular area defined by two blocks you select. It places your sampled block type on the chosen surface, replacing blocks already there.
How To Use
- Choose a material: Sneak-use the Filler on a block. The selected block is shown in the action bar.
- Choose a surface: Use the Filler without targeting a block, select a setting, and press Save.
- Build: Use the Filler on one corner block, then on the opposite corner block. The second use fills the selected surface.
After a fill, select two corners again for the next build. Both corners must be in the same dimension, and you must be in that dimension to complete the fill.
Abilities And Mechanics
The two selected blocks define an inclusive rectangular area:
| Setting | Blocks placed |
|---|---|
| Floor | Horizontal surface at the area’s lowest Y level |
| Roof | Horizontal surface at its highest Y level |
| Walls | The vertical perimeter around the area |
| Full shell | Floor, roof, and walls; the interior remains unfilled |
Each dimension of the selected area can be at most 64 blocks, and a surface can contain at most 4,096 blocks. If an area exceeds these limits, choose a smaller one.
Crafting And Obtaining
The Filler is crafted at a crafting table. Its recipe uses paper, an iron ingot, and a stick.
