Key Features

Interactive 3D View

Drag to rotate, scroll to zoom. Face-culled renderer shows only visible block surfaces. Auto-rotate for presentations.

Layer Slicer with Ghost Mode

Step through every Y-level cross-section. Ghost overlay shows the previous layer as a faint reference, so you never lose your place.

Schematic Export

Export a modern .schem NBT file or a classic .schematic for WorldEdit. Block state baked in, paste directly in-game.

Smart Crosshair

Odd × odd dimensions show a faint centre block. Even × even shows crossing lines. Mixed shows a line on one axis and a highlighted column on the other.

Auto-save

Shape, block, colour, view angle, and layer position are saved to your browser automatically between sessions.

Mobile Friendly

Controls / Preview / Exports tab bar on small screens. Pinch to zoom and drag to rotate work on touch devices.

Calculate Builds

Have an idea of the number of blocks required for the build. Use the summary to know stacks, bounds, and total blocks required for each layer.

Track Block Coordinates

Enter your in-game X / Y / Z in the World Origin to see the coordinates match for your build. Leave at 0 / 64 / 0 for a generic layout.

Quick Presets

Start faster with built-in size presets for spheres, domes, and other popular Minecraft builds. Select a preset and customize to generate your layout instantly.

FAQ

How do I build a Minecraft sphere?
Select Sphere, set your diameter (odd = true centre block), click 2D Layers, then step through each Y-level cross-section with the slider and build layer by layer.
What is .schem export?
The .schem format (Sponge Schematic) is the most widely supported modern schematic format. It can be imported with WorldEdit, FastAsyncWorldEdit (FAWE), Amulet Editor, and many other tools. It works on both Fabric and Forge servers and supports block states and NBT data.
What is Schematic export?
A .schematic file works with WorldEdit ( older tools. Paste the shape directly into your world.
What does Wall thickness do?
Controls shell depth when Solid is off. Wall 1 = single-block shell. For torus, it sets the tube radius. For star/gear, it sets the outline inset.
What is the Curve factor?
Adjusts the profile for dome, cone, paraboloid, hyperboloid, and bowl. Below 1 = wide gentle curve; above 1 = sharp taper. Updates live.
What is the Ghost layer?
In 2D layer view, ghost shows the previous layer's blocks as faint white squares behind the current layer, a handy guide when building upward.
How does the crosshair work?
Odd × odd sizes show a faint highlight on the single centre block. Even × even shows dashed crossing lines at the exact midpoint. Mixed sizes show a line on one axis and a faint column highlight on the other.
Does it work on mobile?
Yes, the layout switches to Controls / Extra tabs at the bottom. Pinch to zoom and single-finger drag to rotate are fully supported.
