  87 <h1>Extrusion</h1>
  88
  89 <p>Extrusion is a type of surface meshing by generation from discretized
  90  lines. It is used to build mesh elements of plus one dimension than the
  91  swept ones. Each swept 1D element produces one or more quadrangles (or
  92  triangles if one node of a rotated element lays on the revolution axis).</p>
