How to build it

  1. Mark the center block of your build area.
  2. Place the outline blocks row by row, following the blueprint.
  3. Keep every ring and row aligned to the same center point.
  4. For spheres and domes, stack each layer directly on top of the previous one.
  5. Finish with the top cap and smooth any harsh steps with slabs or stairs.

Copy it as /setblock commands

Open the generator and hit Copy /setblock to get every block as a Minecraft command. Add your world coordinates and the whole Dome lines up exactly where you want it to be.
