A surface represents the geometry associated with a physical part.  A surface is a two-dimensional geometric entity that may be used in automatic mesh generation.

A surface is comprised of one or more faces.  Each face contains a mathematical surface and edges to trim the surface, if required.  When a surface has several faces, all of the faces are maintained as a single surface entity.  Operations performed on the surface affect all the faces that comprise the surface.  In general, HyperMesh automatically uses the appropriate number of and type of surface faces to represent the geometry.

Surface edges are different from lines and are sometimes handled differently for certain operations.

The connectivity of surface edges constitutes the geometric topology.
