How to use it

  1. Pick a shape and size. Circle, oval, arc, sphere, dome, tower, spiral staircase, arch or pyramid — then how many blocks across (and tall, for the 3D ones).
  2. Build it. Keep this open on your phone next to you. Place the green blocks in your world and tap each one here to grey it out, so you never lose your place.
  3. Or do it instantly (PC only). Tap Copy build commands and paste into the Minecraft chat with cheats on — or Download .schem and paste the build with WorldEdit or Litematica.

Why this is even needed: Minecraft only has square blocks, so anything round has to be faked by stacking squares in just the right stair-step pattern. Getting that pattern right by eye is the headache — this tool does the math so your circles, spheres and staircases come out perfect.

For 3D shapes (spheres, domes, towers, spiral staircases, pyramids) you build one layer at a time: the 3D preview shows the finished build with a gold band on the layer you're working, and the layer view below it shows the exact pattern to place at that height, with Up / Down to move between them. Blocks from the layer below show as a faint ghost so you always know where you are, and blocks you tap off grey out in the 3D preview too — you can literally watch your tower fill in. The block counts tell you how many to gather first.

The spiral staircase generator makes real climbable spirals: every step is walkable from the one below, one step per block of height, clockwise or counter-clockwise, with an optional center column. The arch generator draws the front view of a perfect arch for doorways and bridges — add legs to turn it into a full bridge span. The tower generator stacks a circle to any height, with optional battlements for the castle look.
