51 /// TVolume description
52 ///
53 /// A TVolume object is used to build the geometry hierarchy.
54 /// Since TVolume is derived from TDataSet class it may contain other volumes.
55 ///
56 /// A geometry volume has attributes:
57 /// - name and title
58 /// - pointer to the referenced shape (see TShape).
59 /// - list of TVolumePosition object defining the position of the nested volumes
60 /// with respect to the mother node.
61 ///
62 ///
63 /// A volume can be drawn.
