CartoVoxel Minecraft Shape Maker vs MinecraftCircle Tools

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.

MinecraftCircle Tools is a free web collection for planning Minecraft block geometry. Its circle and oval generator creates symmetrical outline or filled plans with coordinates, layer views, and exports to PNG, Litematic, CSV, TXT, or Markdown; plans can also be shared by URL. Other generators produce hollow or filled spheres, upper-half dome roof plans, and symmetric five-point stars. Sphere views show horizontal slices and layer counts. The sphere and dome interfaces display dimensions up to 129, while the underlying engine and exports support dimensions through 256. Pixel-art images are resized and color-quantized in the browser rather than sent to the server. Circle build progress is kept in browser local storage and, according to the site, is not sent to its server. The site says its grid and row plans describe block positions usable in Java and Bedrock Edition, while Litematic supports compatible Java mod workflows. No account is required. The maker describes the project as independent and not approved by or associated with Mojang or Microsoft. ToolSphere Tech LLC operates the website, whose legal notice provides the tools as-is and as-available.
