class Tool from TopoDSToStep

    ---Purpose: This Tool Class provides Information to build
    --          a ProSTEP Shape model from a Cas.Cad BRep.                 

uses

    Vertex from TopoDS,
    Edge   from TopoDS,
    Wire   from TopoDS,
    Face   from TopoDS,
    Shell  from TopoDS,
    Shape  from TopoDS,
    
    DataMapOfShapeTransient from MoniTool,
    
    TopologicalRepresentationItem from StepShape
