Circle
Use for footprints: towers, wells, arenas, portal rooms, round farms, and any build where the ground plan must be clean first.
Open circle generatorMinecraft Build Tools
Choose a generator, set the dimensions, check the layers, and build from a block plan instead of guessing the curve in-game.

What are you building?
Start with the shape that controls the build. The preview images below show the kind of layer plan each generator is meant to produce.
Cylinder
Use when the same circle repeats upward: towers, silos, pipes, columns, lighthouses, shafts, and circular walls.

Dome
Use for curved roofs, observatories, glass covers, underwater bases, arena tops, and half-sphere structures.
Open dome generator
Sphere
Use for full volumes: planets, balloons, habitats, orbs, organic shells, and hollow or filled round structures.

Not sure yet
Use the all-in-one shape generator when you are still deciding between circle, sphere, dome, pyramid, cone, cylinder, ellipsoid, or torus.
Compare shapesOrganic oval forms
Use separate width, height, and depth for eggs, airships, boulders, stretched planets, organic rooms, and oval terrain pieces.
Open ellipsoid generatorCustom trees
Use procedural trunks, branches, roots, and leaf clusters for custom oaks, spruces, willows, jungle trees, and fantasy trees.

Convert custom 3D models into Minecraft block builds
Use the Minecraft 3D Model Converter when a normal shape generator is too limited. Import GLB, GLTF, OBJ, or STL files, voxelize the model, review the block result, and turn custom statues, props, terrain pieces, and organic objects into Minecraft block coordinates.

Build from the plan
- Decide the outside dimensions first, then check whether the inside space is still usable.
- Use outline or hollow mode for walls, shells, roofs, and frames; use filled mode for floors, terrain pieces, and material estimates.
- For curved 3D shapes, build from the layer view instead of eyeballing the curve from the preview.
- Before survival builds, copy the block count and reduce the palette if the material list is too expensive.

Minecraft generator FAQ
What is the difference between circle, cylinder, dome, and sphere tools?
Use the circle generator for a flat footprint. Use the cylinder generator when that footprint repeats upward. Use dome or sphere tools when each height needs a different layer.
Are these useful for survival mode?
Yes. The useful part for survival is the block count and layer plan: you can gather materials first and build one layer at a time.
When should I use the 3D model converter?
Use the 3D model converter for imported GLB, GLTF, OBJ, or STL files. For simple geometric builds, a dedicated shape generator is usually faster and cleaner.
