CartoVoxel Minecraft Shape Maker vs MC Circle

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.

MC Circle is a web planner for Minecraft players who need block-by-block layouts for circular and curved builds. It generates charts for circles, ovals, half circles, and domes, with outline or filled views and optional grid lines. Numbered rows and columns guide block placement, while block counts and stack estimates support material planning. The main generator accepts sizes from 3 to 128 blocks and states support for Java and Bedrock editions. Plans can be downloaded as PNG files, copied as charts, or shared through links. The site also provides sphere plans with hollow or solid modes, layer counts, and per-layer block plans. Its coordinate output and layer-by-layer view help translate designs into builds. MC Circle runs in a browser without login, registration, payment, or subscriptions. The free plan is listed at free.
