In this paper, the area vectors of the closed spherical indicator of a unit dual sphere and the parallel projection areas of the planar regions surrounded in the lines space of these the closed spherical indicators are calculated in terms of the components of G, Koenigs screw. In addition, a orihonormal trihedron fıxed to the striction point X of an initial nıled surface and some relations were obtained for the parallel projection areas of the spherical indicator of this trihedron.
