The procedure follows the same order as for the geometry creation:
curves are discretized first; the mesh of the curves is then used to
mesh the surfaces; then the mesh of the surfaces is used to mesh the
volumes. This automatically assures the continuity of the mesh when,
for example, two surfaces share a common curve. Every meshing step is
constrained by the characteristic length field, which can be uniform,
specified by characteristic length associated to elementary
geometrical entities, or associated to another mesh (the background
mesh).
