          <string>This field (as well as tolerance) enables the user to control the accuracy of the

+control the maximal angle allowed between two adjacent faces. It can be used to
 bound the maximal deviation of the mesh faces from the tangent planes at mesh vertices. 
 In other words, it avoids having sharp angles between faces representing a smooth curve.
 This parameter enables the user to specify the maximal chordal deviation &quot;max relatively to the curvature.
 Following that criterion:
-- if the chordal deviation epsilon  is smaller than epsilon max *r, it is acceptable to remove the considered point;
+- if the chordal deviation epsilon is smaller than epsilon max*r, it is acceptable to remove the considered point;
 - if the chordal deviation epsilon is greater than epsiolon max*r, the considered mesh face should be redefined 
-by adding a point on the curve.
+     by adding a point on the curve.
 One can see that the smaller the radius r, the harder it is to satisfy this criterion:  
 epsilon max is a real value corresponding to a percentage, the ratio between the chordal deviation to 
 the local curvature. This field is used only for optimisation style -O values of  -1, 0 and 1.
 The default value for &quot;max is set to 0:04 which leads to angles of less than 33 degrees between two adjacent
