The present article aims to address some solutions to the problems of 2D and 3D graphical documentation in contemporary art objects. The garden bench by Júlio Resende in the Parnaso building located in the city of Porto was selected as a case study. With the combination of some systems of representation, it was intended to collect a comprehensive set of information that would enable the characterization of the object, as well as to establish the relation of applicability of the documentation methodology to the specific issues of the work with emphasis on support in the definition of intervention criteria and methods and, consequently, to present a documentation methodology for contemporary art. Starting from these premises the survey will be approached in different ways through 2D graphic registration, photogrammetry and 3D computer graphics.
