WHY IT EXISTS

Why This Tool Exists

The Problem

Structural engineers interrupt their parametric design workflow to set up external FEA software, losing design intent and efficiency. Running separate structural analysis tools prevents real-time design iteration and forces repetitive model setup for each design variation.

The Solution

Embeds parametric FEA directly in Grasshopper, enabling instant structural analysis feedback without leaving the design environment. Engineers can optimize structures for performance while maintaining full parametric control, testing multiple design iterations in minutes instead of hours.
