A different projection strategy has been implemented in the

+OpenCASCADE::NormalProjectionManifold class. The <code>TopoDS_Shape</code>
assigned at construction time can be arbitrary (a collection of shapes, faces,
edges or a single face or edge will all work). The new cell nodes are first
computed by averaging the surrounding points in the same way as FlatManifold
elements of suitable quality. This is because the direction normal to the CAD
surface has in principle nothing to do with the direction along which the mesh
needs the new nodes to be located. The
-OpenCASCADE::DirectionalProjectionBoundary class, in this case, can help. This
+OpenCASCADE::DirectionalProjectionManifold class, in this case, can help. This
class is constructed assigning a <code>TopoDS_Shape</code> (containing at
least a face) and a direction along which all the projections will be carried
out. New points will be computed by first averaging the surrounding points (as
identified. In cases in which the surface direction is approaching the
projection direction, it is even possible that the directional projection is
not found. To overcome these problems, the

estimate of the direction normal to the mesh elements to be refined, and uses
it for the projection of the new nodes onto the CAD surface. If we consider a
