Hyperboloid and Parabolid in Orthogonal Axonometric

Abstract

This paper presents the issue of a long research on the representation of the complex surface in descriptive geometry. The ability to use the different techniques of representation aims to achieve results that you didn’t image before. In Palermo University, at the Engineering School, the researcher involved the study on the simplify of the so elaborated way to represent the geometry and its applications in architecture buildings and engineering implants. We just report below the application methods to represent two of the most used quadric surfaces in the practice of buildings. We are talking about Hyperboloid and Paraboloid quadric surface represented in axonometric projecting. This method is the result of the experimental homology applied to the axonometric projection. We’d like to have the opportunity to show the method that is beyond the below application and hope to have this choice in an other time. We remained to the bibliography of the other works where there is explained the theory method to become to the application.
