CartoVoxel Minecraft Shape Maker is a free web tool for planning block geometry with a live 3D preview and coordinate exports. It provides 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 toggle filled geometry. A layer view displays generated coordinates in a grid one Y level at a time. Export options are a browser-readable layer guide, JSON coordinates and shape settings, and a Java mcfunction intended for Minecraft Java Edition creative worlds or datapack workflows. Shape generation, previews and downloads run locally in the browser after the page loads; the page says shapes and settings are not uploaded. The tool does not create Litematic, schem, Bedrock structure, mcworld or complete world files. CartoVoxel describes the service as web-based, with no downloads or heavy software required. The listed plan is free and includes all 11 shapes, live 3D and layer views, and the stated exports.
