:: Generates a manifold face in the first encountered shell of the NMG object. Vertices are listed as the ''suffix'' and define the winding-order of the face. Faces require at least three specified vertices, each specified by three coordinates. In addition to creating a face, the subcommand will join edges of the new face with dangling edges of other faces in the same shell. This makes it easier for the application to generate topologically correct, closed, manifold objects. | :: Generates a manifold face in the first encountered shell of the NMG object.
