This article is about an experience in the course of .Informática Aplicada à Arquitetura. for architecture students, at the Universidade Estadual de Londrina, applied on the the 2nd year, in a period between 1998 to 2003. We present an evaluation of three moments of this experience, thinking of the representation, the use of images and the easy way of constructing digital objects. The intentions were integrate theoretical knowledge on the space and digital three-dimensional exercises. From all experinces, all the process, exercises and their results we can stand out two reflections: the danger of the image used as a discard object and the construction of forms without conscience.
