FAQ

How do you build a sphere in Minecraft?

A sphere is a stack of circles that grow toward the middle and shrink again. Build it from the bottom up, one layer at a time, using the layer slider to see each circle.

How many blocks does a sphere take?

A hollow 15-block sphere uses 530 blocks; a hollow 21-block sphere uses 1,082. The table above has more sizes, and the stats panel shows the count for any size.

What is the WorldEdit command for a sphere?

Use //sphere <block> <radius> for a solid sphere or //hsphere for a hollow one. For a 21-block sphere the radius is 10. The generator writes the command for the size you pick.

What is the difference between hollow and filled?

Hollow keeps only the shell, which is what you want for a base or biodome. Filled includes every block inside and uses many more blocks.

How do I build half a sphere?

Use the dome generator. It shows only the top half, starting from the widest layer.
