GSA Grasshopper plugin


The GSA-Grasshopper plugin will run GSA inside Grasshopper using GSA's .NET API.

You can create parametric models from scratch or open and edit existing models, carry out analysis in real-time, and view the results on the fly inside Rhino.

The GSA plugin enables computational design and automated workflows for structural engineers, utilising the powerful geometry engine in Rhino and the low-entry, visual scripting of Grasshopper.
