CartoVoxel Minecraft Shape Maker
What it is
CartoVoxel Minecraft Shape Maker is a free web tool for planning Minecraft block geometry and preparing build-ready exports. It offers 11 shapes: sphere, cylinder, cone, pyramid, dome, prism, torus, ogive cone, hyperboloid, star, and spiral. Users can adjust dimensions, select a material color preset or Minecraft block ID, and choose whether the geometry is filled. A live 3D preview and a layer view help show the shape; the layer view presents generated coordinates as a grid, one Y level at a time. Exports include a browser-readable layer guide, JSON coordinates and shape settings, and a Java mcfunction for Minecraft Java Edition creative worlds or datapack workflows. Generation, previews, and downloads run locally in the browser after the page loads, and the page says shapes and settings are not uploaded. The web tool requires no software download. Its exports do not include Litematic, schem, Bedrock structure, mcworld, or complete world files.
For and against
For
- Offers 11 adjustable shape types.
- Includes live 3D preview and layer view.
- Exports JSON, a layer guide, and Java mcfunction.
- Shape processing runs locally in the browser.
Against
- Does not create Litematic or schem files.
- Does not export Bedrock structures or complete worlds.
- Java mcfunction is intended for Java Edition workflows.
The verdict
CartoVoxel Minecraft Shape Maker provides a free way to design geometry and inspect its coordinates before building. Check the export limits if your workflow depends on formats beyond JSON, a layer guide, or Java mcfunction.
Who it suits
This tool suits Minecraft builders who want to plan block shapes, inspect coordinates by layer, and use Java mcfunction or other listed exports. It may also fit users who prefer a browser tool that processes shapes locally after loading.
