Function make_band_of_rings 

pub fn make_band_of_rings(
    model: &mut Model,
    surface: &SurfaceGeometry,
    ring_a: &[Shape],
    ring_b: &[Shape],
    tol: Tolerances,
) -> OgeomResult<Shape>

Build the face of a band between two closed rings of edges on a periodic analytic surface, joined by a synthesised seam.

make_revolution_band for rings of any number of edges, each edge a curve with a closed-form pcurve on the surface: a notched rim of arcs and rulings, not only a whole circle. Each ring is the edge occurrences of a closed wire in order, the first starting on the seam’s column; a ring of one degenerate edge stands for a pole or an apex. The first ring is walked as given and fixes the seam’s column and which way round the band runs; the second is walked back the other way, reversed if it was given winding the same way, and the seam joins the two start vertices along the surface’s iso-curve. The face is built on a fresh copy of the surface.

Errors

OgeomError::Construction if the surface is not a periodic analytic surface, a ring does not go once round it, the rings’ start vertices do not share a column, an edge has no closed-form pcurve, or the iso-curve has no closed form.
