The geometries of screw systems are well-defined in some special bases such as in the principal coordinate systems. However, it is not easy to construct the principal coordinate system of a screw system from a given set of screws. Methods of finding the special bases of two- and three-systems by means of linear algebra are presented. Geometric characteristics and their difference between screw systems are discussed and illustrated in the special bases.
