build() Code Mode (RECOMMENDED)

Sphere

build(code=""" commands = [] cx, cy, cz, radius = 105, 70, 205, 10 for x in range(cx - radius, cx + radius + 1): for y in range(cy - radius, cy + radius + 1): for z in range(cz - radius, cz + radius + 1): if ((x-cx)**2 + (y-cy)**2 + (z-cz)**2)**0.5 <= radius: commands.append(f'/setblock {x} {y} {z} stone') """, description="Solid sphere")

Hollow Sphere

Add: if radius - thickness <= dist <= radius:

Dome (Half Sphere)

Limit y range: for y in range(base_y, base_y + radius + 1):

Use: dist = ((x-cx)**2 + (y-base_y)**2 + (z-cz)**2)**0.5

Cylinder

build(code=""" commands = [] cx, cz, base_y, radius, height = 105, 205, 64, 8, 20 for y in range(base_y, base_y + height): for x in range(cx - radius, cx + radius + 1): for z in range(cz - radius, cz + radius + 1): if ((x-cx)**2 + (z-cz)**2)**0.5 <= radius: commands.append(f'/setblock {x} {y} {z} stone_bricks') """, description="Solid cylinder")

Hollow: if radius - thickness <= dist <= radius:

Cone

Per layer: radius = base_radius * (1 - (y - base_y) / height)

Pyramid

build(code=""" commands = [] cx, cz, base_y, half = 105, 205, 64, 10 for layer in range(half + 1): size = half - layer for x in range(cx - size, cx + size + 1): for z in range(cz - size, cz + size + 1): commands.append(f'/setblock {x} {base_y + layer} {z} sandstone') """, description="Pyramid")

Torus (Donut)

build(code=""" commands = [] cx, cy, cz, major_r, minor_r = 105, 70, 205, 12, 4 for x in range(cx - major_r - minor_r, cx + major_r + minor_r + 1): for y in range(cy - minor_r, cy + minor_r + 1): for z in range(cz - major_r - minor_r, cz + major_r + minor_r + 1): dist_xz = ((x-cx)**2 + (z-cz)**2)**0.5 tube_dist = ((dist_xz - major_r)**2 + (y-cy)**2)**0.5 if tube_dist <= minor_r: commands.append(f'/setblock {x} {y} {z} gold_block') """, description="Torus")

Spiral Staircase

Use: angle = step * (2 * pi / steps_per_rotation)

x = cx + cos(angle) * radius, z = cz + sin(angle) * radius

Facing based on angle quadrant

Arched Bridge

Use: arc = sin(progress * pi) * arc_height where progress = (x - start) / length

Shape Formulas

Shape Formula

Sphere x² + y² + z² ≤ r²

Ellipsoid (x/a)² + (y/b)² + (z/c)² ≤ 1

Cylinder x² + z² ≤ r²

Cone x² + z² ≤ (r(1-y/h))²

Torus (√(x²+z²) - R)² + y² ≤ r²

Tips

• Hollow > Solid (fewer blocks)

• Preview first: build(preview_only=True)

• Use /fill for rectangular parts
