The construction of a new bridge interferes with the existent environment. A careful aesthetic study must be made at an early stage in the design and the visualisation of a three-dimensional (3D) model of the structure is the best way to analyse it. As the bridges deck presents a complex shape it is difficult to execute a 3D deck model as well as the specific drawings or a 3D finite elements mesh of the deck.The modelling scheme proposed here allows the automation of the geometric design phases related to the deck element using as a means of integration a geometric database representative of the real deck shape. This concept was implemented in a computer programme. This application is an important support in a bridge design namely at the conceptual, analytical and final stages.
