A face is a surface bounded by edges. One or more loops of edges bound a face. A face can bound a solid region, be embedded in a solid region, or only represent a 2D region. It is implemented in the class FACE.

A face can be double-sided, in which case it is infinitely thin. It can also be single-sided, in which case the face normal points away from one side of the face, and solid material is present on the other side of the face. A single-sided face is a solid body, not a sheet body.

See also double-sided face, edge, lump, wire, shell, single-sided face.
