pub fn face_boundary_in_chart(
model: &Model,
face: &Shape,
deflection: Deflection,
tol: Tolerances,
) -> OgeomResult<Vec<Vec<Point2>>>Expand description
face_boundary, each ring keeping within the chord of its edges in
the chart too, read in space through the surface’s tangent scales: a
point on an edge then lies within the chord of its ring however much
more the edge bends in the chart than in space.
The rings to place points against. face_boundary’s are drawn at the
points a mesh welds its faces along, and keep to their edges in space
only: a parabola where a cone meets a plane drafted as the cone is bends
little in space and much in the cone’s chart, and its ring stands off it
there by more than the chord.
