pub fn crosses_extrusion_rim(
a: &SurfaceGeometry,
b: &SurfaceGeometry,
tol: Tolerances,
) -> boolExpand description
Whether a and b are a plane and an extrusion of a B-spline profile
whose control points’ heights to the plane straddle an end of the
sweep: the pair plane_extrusion_at_rims answers, and
intersect_surfaces leaves to the
marcher.
