Minecraft Sphere & Dome Generator
Generate pixel-perfect spheres and domes for Minecraft builds.
Sphere and dome layouts for Minecraft builds
This tool generates precise block layouts for building spheres and domes in Minecraft. Use it to plan round structures, planetarium domes, observatory roofs, and any 3D curved build where you need consistent, accurate block placement.
The 3D isometric view gives you a live preview of the entire structure from an angled perspective — rotate-free but with proper depth layering. Switch to layer view to inspect each horizontal Y-level as a flat 2D grid, perfect for following along block-by-block while building in game.
Choose Sphere for a complete ball, or Dome for the upper half — ideal for rooftops and igloo-style builds. Enable Filled for a solid structure, or leave it off to get just the shell (hollow sphere or dome).
