摘要：This paper deals with the issue of a long time research concerning the representation of complex surfaces in descriptive geometry. The ability to use the different techniques of representation aims to achieve results never thought before. In the University of Palermo, at the Engineering School, the research involved the study on simplifying a more elaborated way to represent the geometry and its applications in buildings architecture and related engineering plants and equipment. Specifically, is here reported the application of the proposed method to represent one of the most used surfaces in the buildings design. It concerns a helicoid surface represented in orthogonal axonometric projecting. The method is essentially based on the experimental homology that, by the way, is extensively documented in the bibliography section of this paper.
