@ -55,6 +55,14 @@ Vertices</b>, which belong to the same edge of the created \b Face.
For groups of face, they must contain equal number of faces
and they must form topologically equal structures.
\n <b>Projection 1D-2D</b> algorithm differs from <b>Projection 2D</b>
algorithm in one point, namely it generates mesh segments on edges of
the face according to the projected 2D elements; thus it does not
require that edges to be meshed by any other 1D algorithm; moreover it
does not allow to mesh edges of the face using another algorithm via
definition of sub-meshes.
\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
only if all faces and edges of the target shape have been meshed as 1D-2D
