+<h2>Quality Information</h2>
+
+The <b>Quality Info</b> tab provides overall information about mesh quality controls on the selected object - mesh, sub-mesh or mesh group:
+- Name;
+- Nodes information:
+ - Number of free nodes;
+ - Number of double nodes;
+- Edges information:
+ - Number of double edges;
+- Faces information:
+ - Number of double faces;
+ - Number of over-constrained faces;
+ - Aspect Ratio histogram;
+- Volume information:
+ - Number of double volumes;
+ - Number of over-constrained volumes;
+ - Aspect Ratio 3D histogram.

+\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).
