MinecraftCircle Tools vs MinecraftDome

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.

MinecraftDome is a free, open-source web app that generates dome geometry and construction plans for Minecraft. You draw connected square-mesh surfaces in circles, rectangles, diamonds, ellipses, or hyperellipses, then add anchors to constrain them. Anchors within a layer are treated as points on a plane defined by three points. Shape calculations include parabolic, catenary, and roof loads; setting load values to zero creates a soap-bubble effect. The display can show ideal blocks, a line grid, or Minecraft blocks, with an option requiring adjacent blocks to meet by a face. Generated plans are fixed-width plain text for copying, pasting, or printing. X and Z markers appear every 16 blocks and Y markers every 8, with chunk-line offsets. The documented version has no save, restore, or undo. Catenary calculations can run to infinity, so reset may be needed.
