Boolean Operations

// Union - combine two shapes
sphere(0.5).union(cube(0.7))

// Subtract - cut one from another
cube(1.0).subtract(sphere(0.8))

// Intersect - keep only the overlap
sphere(0.6).intersect(cube(0.8))

// Smooth union - blend shapes together
a.smooth_union(b, 0.1)

// Smooth subtract - filleted cut
a.smooth_subtract(b, 0.1)

// Smooth intersect - filleted intersection
a.smooth_intersect(b, 0.1)
