-\section combining_filters How to combine filters with Criterion structures?
-
-Filters can be combined by making use of "criteria".
+- element type can be any, e.g.: \a SMESH.EDGE, \a SMESH.FACE, \a SMESH.VOLUME, etc.
+- functor type should be \a SMESH.FT_ElemGeomType
+- threshold is either of smesh.GeometryType values. Type \a SMESH.GeometryType._items in the Python Console to see all geometric types.
+
+\tui_script{filters_ex35.py}
+
+\section filter_entity_type Entity type
+
+filters mesh elements by the geometric type and number of nodes.
+- element type can be any, e.g.: \a SMESH.EDGE, \a SMESH.FACE, \a SMESH.VOLUME, etc.
+- functor type should be \a SMESH.FT_EntityType
+- threshold is either of SMESH.EntityType values. Type \a SMESH.EntityType._items in the Python Console to see all entity types.
+
+\tui_script{filters_ex37.py}
+
+\section filter_ball_diam Ball diameter
+
+filters ball elements by diameter.
+- element type should be \a SMESH.BALL
+- functor type should be \a SMESH.FT_BallDiameter
+- threshold is floating point value (ball diameter)
+
+\tui_script{filters_ex38.py}
+
+\section filter_domain Elements of a domain
+
+filters elements of a specified domain.
+- element type can be any, e.g.: \a SMESH.EDGE, \a SMESH.FACE, \a SMESH.VOLUME, etc.
+- functor type should be \a SMESH.FT_ConnectedElements
+- threshold is either (1) node ID or (2) geometrical vertex or (3) 3 coordinates of a point.
