class ManifoldSolid from IGESSolid  inherits IGESEntity

        ---Purpose: defines ManifoldSolid, Type <186> Form Number <0>
        --          in package IGESSolid
        --          A manifold solid is a bounded, closed, and finite volume
        --          in three dimensional Euclidean space

uses

        Shell            from IGESSolid,
        HArray1OfShell   from IGESSolid,
        HArray1OfInteger from TColStd

raises DimensionMismatch, OutOfRange

is

        ---Purpose : returns Index'th void shell.
        -- raises exception if Index  <= 0 or Index > NbVoidShells()

        VoidOrientationFlag(me; Index : Integer) returns Boolean
        raises OutOfRange;
        ---Purpose : returns Index'th orientation flag.
