Parametric tools such as Grasshopper and the scripting capabilities of FEA software packages such as SOFiSTiK FEA allow engineers to automate functionalities to work faster and more creatively.

Besides, it has massive potential to parametrise and optimise structures of any type.

This course teaches the parametric modelling process of a post-tensioned concrete bridge with Grasshopper and SOFiSTiK FEA.

You will learn the fundamentals of Grasshopper to create effective and maintainable visual scripts. And how to use the SOFiSTiK Grasshopper components to build the axis-based bridge structure.
