class SolidInstance from IGESSolid  inherits IGESEntity

        ---Purpose: defines SolidInstance, Type <430> Form Number <0>
        --          in package IGESSolid
        --          This provides a mechanism for replicating a solid
        --          representation.
        --          
        --          From IGES-5.3, Form may be <1> for a BREP
        --          Else it is for a Boolean Tree, Primitive, other Solid Inst.

        Init (me       : mutable;

        --           SolidInstance
        --       - anEntity : the entity corresponding to the solid

    	IsBrep (me) returns Boolean;
	---Purpose : Tells if a SolidInstance is for a BREP
	--           Default is False

    	SetBrep (me : mutable; brep : Boolean);
	---Purpose : Sets or unsets the Brep status (FormNumber = 1 else 0)

        Entity(me) returns IGESEntity;

-- Reminder : A SolidInstance instance is defined by :
