Models are an essential component of the architect's design process. As tools of translation, models assist the exploration of the possible and illustrate the actual. While models have traditionally served as representational and structural studies, they are increasingly being used to suggest and solve new spatial and structural configurations. Models, the eleventh volume of the highly regarded journal 306090, explores the role of the architectural model today in relation to the idea, the diagram, the technique, and the material. Models includes contributions from engineers, scientists, poets, painters, photographers, historians, urbanists, and architects both young and experienced.
