summary	This paper will try to establish a dialogue between the process of rational geometric construction and the intuitive process of discovering shapes. This will involve: a geometric principle that works as a geometric generation law and two interactive macros. The geometric principle is the affinity between circles and ellipses. The macros, developed in VisualLisp languagefor AutoCAD, allow the students to construct 3D abstract structures. In order to provide support for the student in the task of analysing the 3D structures a methodology has been established to classify shapes giving each one an alphanumeric string. The string reflects the transformation order during the creation of each spacial structure. With the aid of interactivity it is intended that this exercise in discovering space creates a tension allowing the rational and intuitive states of mind overlap.
