In this menu you can define the \b Name of the algorithm, the already
-meshed source \b Edge and the \b Mesh (optional, use it if there are several
-different meshes on the same edge). It could also be necessary to
-define the orientation of edges, which is done by indicating the
-<b>Source Vertex</b> being the first point of the Source Edge and the
-<b>Target Vertex</b> being the first point of the created \b Edge. For
-a group of edges, <b>Source</b> and <b>Target</b> vertices should be
+meshed source \b Edge and the \b Mesh (It can be omitted only when
+projecting a submesh on another one from the same global Mesh).
+It could also be necessary to define the orientation of edges,
+which is done by indicating the <b>Source Vertex</b> being the first point
+of the Source Edge and the <b>Target Vertex</b> being the first point of
+the created \b Edge.
+For a group of edges, <b>Source</b> and <b>Target</b> vertices should be
shared by only one edge of the group. If <b>Source</b> and
<b>Target</b> vertices are specified, the elements of the group must be ajacent.

In this menu you can define the \b Name of the algorithm, the already
-meshed source \b Face and the \b Mesh (optional, use it if there are several
-different meshes on the same face). It could also be necessary to
-define the orientation of mesh on the face, which is done by
-indicating two <b>Source Vertices</b>, which belong to the same edge of the
-source face, and two <b>Target Vertices</b>, which belong to the same edge of
-the created \b Face.

\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 face have been meshed as 1D
-Projections of the faces and edges of the source face. Another
+only if all faces and edges of the target shape have been meshed as 1D-2D
+Projections of the faces and edges of the source shape. Another
limitation is that this algorithm currently works only on boxes.
To apply this algorithm select the solid to be meshed (indicated in
