\n The Result of the operation will be a \b GEOM_Object.
+The \b Filter controls allow to automatically pick up entites which satisfy specified
+threshold value(s). The numerical functor for each sub-shape that is compared with
+threshold value(s) is computed according to the shape's topological properties:
+- length for edges and wires
+- area for faces and shells
+- volume for solids, compounds, compsolids
+
+Filtering capabilities are not available for vertices.
+
+In order to filter out some entities:
+- Activate one or two filtering controls by switching on corresponding check boxes;
+- Select required threshold comparator type; the following choices are available:
+ - <b>Less Than</b> or <b>Equal or Less Than</b> for the first comparator;
+ - <b>Greater Than</b> or <b>Equal or Greater Than</b> for the second comparator;
+- Enter required threshold value (values);
+- Press \b Apply button in the \b Filter group.
+
+The entities which satisfy entered filtering parameters will be automatically highlighted
+in the 3D viewer.

\n <b>TUI Command:</b> <em>geompy.CreateGroup(MainShape,
ShapeType),</em> where MainShape is a shape for which the group is
created, ShapeType is a type of shapes in the created group.
