80 <p>Revolution is a type of surface meshing by generation from discretized
\r
81 lines. It is used to build mesh elements of plus one dimension than the
\r
82 swept ones. Each swept 1D element produces one or more quadrangles (or
\r
83 triangles if one node of a rotated element lays on the revolution axis).</p>
