-\note For the perfomance reason, the Aspect Ratio histogram for the big meshes is
-computed only by demand. For this, the user should press the "Compute"
-button (see picture). Also, histogram is automatically computed if the size of the
-elements does not exceed the "Automatic controls compute limit" set
-via the "Mesh information" preferences (zero value means no limit).
+\note It is possible to set "Double nodes tolerance" in the dialog for a local change
+ or via the "Quality controls" in Mesh preferences.

+\note For performance reasons, all quality control values for big meshes are
+computed only by demand. For this, press the "compute"
+button. Also, values are automatically computed if the number of
+nodes / elements does not exceed the "Automatic controls compute limit" set
+via the "Mesh information" preferences (zero value means that there is no limit).
