+
+To add a \b Thickness to a shape in the <b>Main Menu</b> select <b>New Entity - > Generation  - > Thickness</b>
+\n
+It is possible to create a Solid from a Face or a Shell by applying a
+\b Thickness. To do it you should define an \b Object that is a Face or a
+Shell, \b Thickness and to define the thickness direction by means of
+<b>Thicken towards the inside</b> check box.
+

+<b>Example:</b>

+
+It is possible to apply \b Thickness to a Solid. The result of this operation
+is the hollowed Solid. To do it you should define an \b Object that is a Solid,
+\b Faces to be removed from result, \b Thickness and the thickness direction by

+Makes a thick solid from a shape;
+\n
+<em>geompy.Thicken(theShape, theThickness, theFacesIDs=[])</em> -
+Modifies a shape to make it a thick solid.
+
+<b>Arguments:</b> Name + 1 shape (face, shell or solid) + thickness +
