How to use this tool, and the questions players ask most.
Type //cyl stone 5 to create a filled circle or //hcyl stone 5 for a hollow ring with a radius of 5 blocks centered on your position. Add a height parameter like //cyl stone 5 3 to generate vertical cylinders.
Spheres are constructed layer by layer using pixelated concentric circles of decreasing radii plotted with the equation x^2 + y^2 + z^2 = r^2. Build Shape Generators generates slice-by-slice voxel blueprints and exact resource lists for any diameter from 3 to 256 blocks.
Vanilla commands draw circles by executing /execute at @e[type=armor_stand] run setblock ^ ^ ^5 stone while rotating the armor stand incrementally using /teleport @e[type=armor_stand] ~ ~ ~ ~5 ~ in a repeating command block.
A 10x10 circle has a 2x2 block center and requires an outer ring pattern of 4 blocks on each flat side, followed by corner steps of 1-1. The entire perimeter uses exactly 24 blocks.
Standard Nether portals require rectangular obsidian frames between 4x5 and 23x23 blocks, but placing decorative corner stairs or slabs around a 5x5 portal frame conceals the rectangular obsidian outline to produce a circular appearance.
