FAQ

How do you build a dome in Minecraft?

A dome is the top half of a sphere. Start with the widest circle at the base and build smaller circles on top, one layer at a time, until you reach the cap.

How tall is a dome?

A dome is about half its diameter tall. A 21-block dome has 11 layers, including the widest middle ring.

How many blocks does a dome take?

A hollow 21-block dome uses 569 blocks with a 1-block shell. The table lists more sizes.

Is there a WorldEdit command for a dome?

WorldEdit has no dome command. Place a //hsphere with the same radius, then select and clear the lower half. The generator shows the sphere command for your size.

What size dome fits my tower?

Use the same diameter as the tower. If the tower wall is thicker than one block, match the outer edge.
