FAQ
How do I build a circle in Minecraft?
Pick a diameter, then copy the outline row by row from the generator. Odd diameters have a single centre block, even diameters have a 2x2 centre.
How do I build a sphere?
Build it one layer at a time. Each slider position in Sphere layer mode shows one horizontal slice.
