class MakePrism from BRepPrimAPI inherits MakeSweep from BRepPrimAPI
---Purpose: Describes functions to build linear swept topologies, called prisms.
-- A prism is defined by:
-- - a basis shape, which is swept, and
-- - a sweeping direction, which is:
-- - a vector for finite prisms, or
-- - a direction for infinite or semi-infinite prisms.
-- The basis shape must not contain any solids.
-- The profile generates objects according to the following rules:
-- - Vertices generate Edges
-- - Edges generate Faces.
-- - Wires generate Shells.
-- - Faces generate Solids.
-- - Shells generate Composite Solids
-- A MakePrism object provides a framework for:
-- - defining the construction of a prism,
-- - implementing the construction algorithm, and
-- - consulting the result.

---Purpose: Builds the prism of base S and vector V. If C is true,
-- S is copied. If Canonize is true then generated surfaces
-- are attempted to be canonized in simple types

---Purpose: Builds a semi-infinite or an infinite prism of base S.
-- If Inf is true the prism is infinite, if Inf is false
-- the prism is semi-infinite (in the direction D). If C
-- is true S is copied (for semi-infinite prisms).
-- If Canonize is true then generated surfaces

LastShape (me : in out)
---Purpose: Returns the TopoDS Shape of the top of the prism.
-- In the case of a finite prism, FirstShape returns the
-- basis of the prism, in other words, S if Copy is false;
-- otherwise, the copy of S belonging to the prism.
-- LastShape returns the copy of S translated by V at the
-- time of construction.
