A
single-sided face means that points on one side of it are considered to be inside the shell, and points on the other side are considered to be on the outside. The selection of the inside and outside may be the same as, or converse to, that for the surface of which the face is part--depending on the sense of the face. A single-sided face either completely or partially bounds a solid region, with the face normal pointing away from the solid region. (A single-sided face is a solid body, not a sheet body.)
