CartoVoxel Minecraft Shape Maker vs Mcgic 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.

Mcgic Circle Generator creates Minecraft circles, ellipses and sphere slices, with real-time 2D and 3D previews. It runs in a browser and supports shapes from 1 to 512 blocks wide, with block counts, coordinates and a layer-by-layer guide. Builder Mode can guide block placement step by step or let users mark blocks directly on the canvas. Designs can be exported as PNG, SVG, JSON with world coordinates, or a .schem file compatible with WorldEdit and MCEdit. The tool has Dark, Light, Forest, Ocean and Classic themes, and saves settings in the browser to restore the last session without an account. On phones, Controls, Preview and Export tabs accompany pinch-to-zoom and touch panning. Mcgic says projects and exports remain on the user’s device rather than being uploaded automatically, though it may use minimal anonymous analytics and third-party integrations. The generator works with full blocks only; slab and stair circle generation is planned for a future update. It is free, requires no login and is available on the web, Android and iOS.
