//! Describes functions to build hollowed solids.
//! A hollowed solid is built from an initial solid and a set of
//! faces on this solid, which are to be removed. The
//! remaining faces of the solid become the walls of the
//! hollowed solid, their thickness defined at the time of construction.
//! the solid is built from an initial
//! solid ~~ and a set of faces {Fi} from ~~~~,
//! builds a solid composed by two shells closed by
//! the {Fi}. First shell is composed by all
//! the faces of ~~~~ expected {Fi}. Second shell is
//! the offset shell of .
//! A MakeThickSolid object provides a framework for:
//! - defining the cross-section of a hollowed solid,
//! - implementing the construction algorithm, and
//! - consulting the result.

//! Constructs a hollowed solid from
//! the solid S by removing the set of faces ClosingFaces from S, where:
//! Offset defines the thickness of the walls. Its sign indicates
//! which side of the surface of the solid the hollowed shape is built on;
//! - Tol defines the tolerance criterion for coincidence in generated shapes;
//! - Mode defines the construction type of parallels applied to free
//! edges of shape S. Currently, only one construction type is
//! implemented, namely the one where the free edges do not generate
//! parallels; this corresponds to the default value BRepOffset_Skin;
//! Intersection specifies how the algorithm must work in order to
//! limit the parallels to two adjacent shapes:
//! - if Intersection is false (default value), the intersection
//! is calculated with the parallels to the two adjacent shapes,
//! - if Intersection is true, the intersection is calculated by
//! taking account of all parallels generated; this computation
//! method is more general as it avoids self-intersections
//! generated in the offset shape from features of small dimensions
//! on shape S, however this method has not been completely
//! implemented and therefore is not recommended for use;
//! - SelfInter tells the algorithm whether a computation to
//! eliminate self-intersections needs to be applied to the
//! resulting shape. However, as this functionality is not yet
//! implemented, you should use the default value (false);
//! - Join defines how to fill the holes that may appear between
//! parallels to the two adjacent faces. It may take values
//! GeomAbs_Arc or GeomAbs_Intersection:
//! - if Join is equal to GeomAbs_Arc, then pipes are generated
//! between two free edges of two adjacent parallels,
//! and spheres are generated on "images" of vertices;
//! it is the default value,
//! - if Join is equal to GeomAbs_Intersection,
//! then the parallels to the two adjacent faces are
//! enlarged and intersected, so that there are no free
//! edges on parallels to faces.
//! RemoveIntEdges flag defines whether to remove the INTERNAL edges
//! from the result or not.
//! Warnings
//! Since the algorithm of MakeThickSolid is based on
//! MakeOffsetShape algorithm, the warnings are the same as for
//! MakeOffsetShape.
