Module boolean_stepped 

Stepped union of two coaxial prisms, as constant-section bands.

boolean_prisms_exact builds a stepped union as ONE exact solid, ledges included (#120, ADR 0072). This module is the older, lighter answer to the same question: cut the union at every height where an operand starts or stops, and return the bands. Within a band the active operand set is constant, so each band is a genuine prism whose section is the planar union of whatever is active there.

Use it when bands are what you want (per-storey quantities, say); use the boolean when you want the solid. The two agree on volume, which the tests check.
