Build guide for this layer (rows front→back, columns left→right)
Build from layer 1 (bottom) upward. Each layer's centre lines up with the one below — the dashed lines mark the centre. For a dome, layer 1 is the widest ring.
Spheres, domes, bowls and ellipsoids — every layer, with a rotatable 3D preview.

Build spheres, domes and bowls without guessing: choose a diameter (or separate height and depth for an ellipsoid), thin shell, thick shell or solid, and step through every layer from the bottom up. The 3D view highlights the layer you're on and ghosts the ones above it; the layer view shows the layer below in grey so alignment is easy. Download one layer, a sheet of all of them, or copy the row-by-row guide.
A 31-block dome gives about 15 blocks of headroom in the middle and needs ~2,100 blocks as a thick shell. Use the totals tile to compare sizes.
