The integration of structural considerations in architectural geometry processing is among the topics most discussed in the complex shapes design. While some design tools allow the designer to begin with an inefficient form and then turn it into a more efficient one, other tools allow exploring and creating structural forms considering both formal and structural aspects from the beginning. This paper presents a parametric design approach to create spatial steel trusses with the combination of two strategies: (1) shell surface to set out structural elements; (2) cross section properties to ensure structural stability aspects. In this paper we discuss how the combination of these strategies can contribute to the use of parametric design techniques in the early stages of the design process, taking into account both structural optimization and production aspects.
