MC Circle Generator vs MinecraftDome

MC Circle Generator is a free web tool for planning circle and oval block layouts in Minecraft. Choose Hollow, Filled or Border+ mode and dimensions; the grid preview updates as dimensions, modes and display options change. A row guide and pattern panel show block placements from the top of the shape to its center, while the Build Materials panel totals blocks and stacks of 64 and 16. The preview can show X/Y coordinates, and coordinate labels can also be included in exports. Blueprints download as PNG or SVG, with options for grid lines, guides, coordinates, a center marker, title, scale and background. The maker says exported layouts work with Minecraft Java and Bedrock editions, and describes the tool as responsive on PC, tablet and mobile. Ready-made reference sizes run from diameter 3 to 65. The page notes that larger pixelated circles appear rounder, while small ones can show staircase artifacts. It is intended for builders planning features such as chimney caps, arena floors, towers and mega-build foundations. The page states that the tool is not affiliated with Mojang or Microsoft.

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.
