About SeedView Build Studio
See your build before you place a block. SeedView Build Studio plans circles, ovals, spheres, domes and pixel art block by block, shows them in 3D, and exports them to the game.
What it does
- Plans round shapes on the same square block grid the game uses, with exact block counts and run patterns.
- Shows the build in 3D and layer by layer, with a phone build mode that keeps your place.
- Exports to
.litematicand.schem(Java),.mcstructure(Bedrock) and.mcfunctioncommands. - Turns an image into a block plan with a material list in stacks and shulker boxes.
How the numbers are made
Every count, pattern and picture on this site is computed by our own shape engine, not typed in by hand. The rule is written on every page: a block is part of a shape when the centre of the block lies inside the ideal shape. Before each release an automatic check recomputes the numbers on every size page and stops the release if one is wrong.
Game facts (file formats, commands, limits) were checked against the sources listed on each guide and on the credits page, for Java Edition 1.21.x and 26.x (checked on 26.3) and Bedrock Edition 1.21.x and 26.x. Last checked 21 Oct 2026.
What it doesn't do
- No accounts and no sign-up. Your build progress stays on your device.
- No game textures, models or logos: blocks are drawn as flat colours we measured ourselves.
- It does not change your world by itself: you place the blocks, or you load an export with your own tools.
Who makes it
SeedView Build Studio is a small independent fan project. It is free to use. If ads are added later, they will never sit inside the tool or the build mode.
