The structural efficiency and the architectural appearance of building forms is becoming an increasingly important field of engineering, particularly because of the present wide-spread availability of computer facilities. The realisation of complex shapes comes into reach, that would not have been possible with the traditional means. In this contribution a technique is described, where structural forms are visualised starting from a geometry based on that of regular or semi-regular polyhedra, as they form the basis of most of the familiar space frame systems and of geodesic sphere subdivisions that are utilised nowadays. It appeared possible to generate these polyhedra by the rotation of regular polygons around the centre of the co-ordinate system. Related figures, that are found by derivation from these polyhedra, can be formed in a similar way by rotating planar figures that differ from ordinary polygons.
