+            The actual grid spacing can slightly differ from the defined one. This is done for the
+            best fitting of polyhedrons and for a better mesh quality on the interval boundaries.
+            For example, if a constant **Spacing** is defined along an axis, the actual grid will
+            fill the shape's dimension L along this axis with round number of equal cells:
+            Spacing_actual = L / round( L / Spacing_defined ).
 
         Examples:
             "10.5" - defines a grid with a constant spacing
