Parametric design is all about setting up relationships between variables. Change one variable, and you can change the entire design. In architecture and design, this approach is powerful. It allows designers to explore countless variations and adapt forms quickly. Grasshopper, a plugin for Rhino, is a tool that makes this process accessible. With Grasshopper, you build algorithms visually, connecting nodes that represent operations like shaping, transforming, or setting dimensions. It’s drag-and-drop, so you don’t need a coding background to get started. For digital fabrication, this setup is ideal—it lets designers adjust, test, and optimize their designs for production, all within a flexible, visual framework.
