Block Shape Generator vs MinecraftDome

Block Shape Generator is a free web tool made for builders to create block-based shapes. Users can select a sphere, cone, dome, or cylinder, then set a radius or diameter, height, and color. A hollow-shape control creates a shell. The preview includes zoom controls and a grid-lines toggle, and the interface displays the number of blocks required. Users can inspect the current layer or view the top layer in 2D before using Generate Shape to create the selected form. The page recommends Google Chrome or Opera and reports that Edge is not compatible. It also displays controls labelled Unlock features and Enable Model Movement, each marked with a test-tube symbol, but gives no explanation of their terms. The maker invites users to suggest ideas through its official Discord server and links to a donation page for development support. The listed free plan states no numeric limits. The page does not state security, privacy, or compliance practices, so readers looking for those details will not find them here.

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.
