pub fn face_boundary_length(
solid: &BrepSolid,
face: &FaceRecord,
) -> Result<f64, String>Expand description
Total 3D arc length of a face’s boundary edges: the unique edges referenced by
the face’s loop coedges, resolved against the owning solid’s edge table and
summed once each. An edge referenced twice by the same face (e.g. a seam) is
still counted once.
