Circle, Sphere & Dome Generator

Plan Minecraft circles, spheres and domes

Choose a circle, sphere or dome and enter its dimensions, then generate a block plan. Select hollow or filled construction to compare an outline with a solid shape. The tool shows how a curved design fits Minecraft blocks without needing to guess each row.

Use the 2D layer view while building. Select a layer with the slider, layer number or previous and next buttons. Grid and previous-layer options help you align the next row. In the 3D view, Show up to layer reveals the build from the bottom to your chosen height.

Reset view fits the full shape, even when some layers are hidden. Rotate the 3D model to inspect its form, then download a PNG plan or copy a link to return to the same settings. The generator creates a building reference; it does not place blocks into a world.
