\n <b>Projection 2D</b> algorithm allows to define the mesh of a face

In this menu you can define the \b Name of the algorithm, the already
meshed source \b Face and the \b Mesh (It can be omitted only when
projecting a submesh on another one from the same global Mesh).

\n <b>Projection 3D</b> algorithm allows to define the mesh of a shape by
the projection of another already meshed shape. This algorithm works
