Params Components | Grasshopper Component Guide

Back to Grasshopper Components Index

This page provides an overview of Grasshopper Params components.

Params components are fundamental elements used to temporarily store and pass data such as numbers, points, curves, and surfaces within a definition.

Various Params play a key role in input handling, data management, and organization across an entire Grasshopper definition.

While these components can be challenging for beginners at first, understanding them greatly improves readability and structural clarity as definitions become more complex.

On this page, commonly used Params components are organized with quick access to detailed explanation articles.

Please refer to the appropriate components based on your specific goals and workflows.
