Parametric drawing and informatic modeling

The issue is that of construction, with the drawing of a complex model subject to investigations which go much further than searches for information traditionally connected with the world of drawing. Compliance and semantic factors sit side-by-side in parametric design and in this case these specifics enable design to escape its static condition to assume the dynamic character of its interactive nature as a graphic representation of a model. Interactive computer models provide opportunities that were unimaginable with physical models and they constitute a combination of a three dimensional plastic model or its digital equivalent (except for some important differences) and a prototype model, once very common among producers in disciplines such as building construction and hydraulics. They conserve the continuous development and propensity to change of a plastic model and at the same time they possess the semantic richness and the quantitative feasibility of a prototype. When interrogated, electronic representation responds with information that is no longer rigid, but which dialogues with data that can change with changes in input conditions: this behaviour not only occurs in the singularity of each parameter but rather in the changed relations of the whole.
