0030 //! Describes functions to build linear swept topologies, called prisms.
0031 //! A prism is defined by:
0032 //! -   a basis shape, which is swept, and
0033 //! -   a sweeping direction, which is:
0034 //! -   a vector for finite prisms, or
0035 //! -   a direction for infinite or semi-infinite prisms.
0036 //! The basis shape must not contain any solids.
0037 //! The profile generates objects according to the following rules:
0038 //! -   Vertices generate Edges
0039 //! -   Edges generate Faces.
0040 //! -   Wires generate Shells.
0041 //! -   Faces generate Solids.
0042 //! -   Shells generate Composite Solids
0043 //! A MakePrism object provides a framework for:
0044 //! -   defining the construction of a prism,
0045 //! -   implementing the construction algorithm, and
0046 //! -   consulting the result.
