pub fn build_swept_envelope(
    plan: &SweptEnvelope,
) -> Result<Vec<BrepSolid>, String>
Expand description

Build the swept union: the APPLE first, then the LEMON where the turn leaves one outside it.

One body for a FULL turn (the lemon is inside the apple) and for a section merely TANGENT to the axis (there is no lemon); two for a turn under half a revolution. A turn in [π, 2π) is refused by name — the far lobe then OVERLAPS the near one and the union is no longer two disjoint revolves.
