This research was carried out through a research of didactic engineering type, for which elements of the design carried out by Rueda y Niño (2013) with the Cabri LM software were re-adapted to the tools available in the CaRMetal software; This adaptation included the reprogramming of the operation of the activities, the automation of the return actions and the restructuring of the a priori analysis. The work aims to observe to what extent the CaRMetal software enables the automation of devolution acts.
