CartoVoxel Minecraft Shape Maker vs Pixel Circle Generator

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.

Pixel Circle Generator is a free web tool for making Minecraft circles, ellipses, arcs, and spheres. Shapes can be outlined or filled, with configurable outline thickness. Dimensions use radius or diameter controls; ellipses add an Ry setting, and arcs accept start and end angles. Sphere previews show one layer at a time from −R through +R, with an option to copy commands for every layer. Generated designs can be downloaded as PNG or SVG, copied as grid text, or converted to /setblock commands for one layer or all sphere layers. Preview controls adjust pixel size, block color, grid, and axes. The tool provides coordinate output and layer-by-layer viewing, but no 3D preview. It runs in a browser and has a free plan priced at free. The site states that it is not affiliated with Mojang or Microsoft.
