Advancements in microelectronics have enabled both miniaturization and portability of computer equipment and, especially, the individual use of it. Thus, this technology have been introduced in the research of the Laboratory for Investigation in Living Design – LILD, Department of Arts and Design from the Pontifícia Universidade Católica do Rio de Janeiro, Brazil – by its members, and their personal computers, as a way to support the development of their studies. This study focuses on the observation of the systematic introduction of computer graphics technology in the LILDs trial and error approach, and aims to present the usage of this tool serving as a new platform to the researches that have been developed in the laboratory. In this manner, this research demonstrates what was observed during the application of this new technology in ongoing studies; as well as their interactive relation with traditional methods, which involves mechanical models, be it in reduced scale or ready to use. As a result, it is verified an enrichment of the researches in course in the laboratory, mainly, in relation to the aspects of precision, documentation and transportation of models; and also concerning new ways of visualization and reflection, different from traditional ones, previously non-existent to the application of computer graphics.
