-- <b>Max plate criterion value</b>, which is computed as <em> max(0.0001,10*error), </em> where error is a 3D tolerance of the surface.
+- <b>3D tolerance of initial approximation</b>
+
+\note <b>3D tolerance of initial approximation</b> represents a tolerance of
+initial plate surface approximation. If this parameter is equal to 0 (default),
+its value is automatically computed as <em> max(0.0001, 10*error)</em>,
+where <em>error</em> is a 3D tolerance of the surface representing a maximal
+distance between computed plate surface and given points.
