Questions & reference

How many blocks does this plan need?

The selected size and fill use 569 blocks: 8 full stacks and 57 blocks. Transporting them requires 1 Shulker Boxes of 27 stacks.

How do I read the grid and its rows?

The plan is a top view. Place a block in every white cell and leave empty cells clear. X runs left to right and Z top to bottom, starting at 1. Select a row for its exact X ranges. For a sphere or dome, move up one block for each new layer.

How do the fill modes differ?

Thin shell retains the outer blocks. Thicker shell adds blocks around diagonal edges. Solid fill includes the interior. A dome is open underneath, so plan its floor separately.
