The splitting direction is defined by the orientation of the
underlying geometrical edge.
-<b>Reverse Edges</b> list box allows specifying the edges, for which the splitting should be made in the
-direction opposite to their orientation. This list box is filled after a geometry object is selected for meshing. In this case it is possible to select edges to be reversed either directly picking them in
-the 3D viewer or by selecting the edges or groups of edges in the
-Object Browser.
