The parametric design tools could be considered one of the digital creativity tools for the architect. BIM platforms trend to simplify the work of designers and engineers if they keep their products within the standards. Then, creativity and information modelling are frequently in contrast within the digital construction field. An interaction between parametric design and BIM platform is necessary to avoid the influence of predefined parametric elements on the design concept. This paper by Wissam Wahbeh will discuss the recent use of parametric design tools as Grasshopper and DynamoBIM within BIM process. Furthermore, how the geometrical solutions could be arranged to optimize the interactivity of the final models.
