Enhanced design and modelling productivity with Parametric design

                                
==Abstract==

This paper focuses on the use of modern parametric design and modelling tools to accelerate the challenging and difficult large design projects. The methodology is also suitable in dealing with renovation and/or modification in the existing structures. Two project examples are presented here namely, construction of membrane façade to existing structure of football stadium Metz, France and renovation of the roof of main train station Dresden, Germany. The structures have deformations with the passage of time and the renovation is more complicated as compared to the theoretical form. Parametrization makes the tasks feasible with enhanced productivity, efficiency and accuracy
