 == Trim to mask ==
 
-This option allows some simple mesh editing.  It works with the delineator, you need to load a suitable 2D template into the delineator and adjust the points and lines to match the face.  When you clikc "Trim to mask" it will prompt for a Mask file (.msk) which can be created in JPsychomorph.  The masked areas will be removed from the mesh.  An invert options is also provided that remove all points within the masked area, instead of those outside the mask area.

+== Normals and smoothing ==
+
+The mesh can be smoothed using Edit->Smooth, which replaces each vertex by an area weighted sum of adjacent vertices.  This can result in some shrinkage of the mesh around the edges (e.g. holes will get a little bigger).  Normals should be recalculated after smoothing using the "Edit->Recalculate normals" option.
 
 == Rigid alignment options ==
 
-A mesh can be rigid aligned to another mesh with the same mesh topology (i.e. number of vertices etc), to a 3D template or to a standard reference frame based on 3 points.
+A mesh can be rigid aligned to another mesh with the same mesh topology (i.e. number of vertices etc) using "Edit->Rigid body normalise", to a 3D template using Edit -> Rigid Body Normalise (T3D) or to a standard reference frame based on 3 points using oe of the Edit -> Orientate 3 points options.  The first two will prompt for the mesh or template respectively.  For the 3 point orientation the first 3 points of a 3D template will be used.  The "Orient 3 point" option uses the first point as the origin (0,0,0) the direction between the second and third points is constrained to lie in the
