Abstract

This paper presents the intersection between two polyhedra in various systems of representation: the orthogonal projection on two planes of projection, the axonometric projection and the projection with elevations. A comparative analysis of the advantages and disadvantages produced by the representation in the three mentioned systems of representation is also performed. Then, suggestions as to the selection of one or another system of representation are also made, in view of finding a clearer spatial visual perception of the unit.
