Parametric Geometry

Parametric geometry is a computer-aided design method in which geometric forms are generated and controlled through parameters—predefined variables and mathematical rules—rather than through direct manual manipulation.

Technical Overview
In a parametric model, designers define relationships, constraints, and logic that govern how each part of the geometry behaves. Changes to a single parameter (such as length, angle, or curvature) automatically propagate throughout the model, updating dependent shapes and configurations in real time.

This approach enables efficient exploration of multiple design variants without rebuilding the geometry from scratch. It supports rule-based logic, adaptability, and the automation of repetitive modelling tasks.

Applications

• Architecture: Designing climate-responsive building facades or optimising spatial performance based on light, airflow, or structural constraints.
• Industrial design: Enabling mass customisation of consumer products by altering only key dimensions while maintaining form coherence.
• Engineering: Automating component design for performance, cost or material efficiency.

Parametric geometry is a foundational concept in generative design, Building Information Modelling (BIM), and computational modelling environments such as Rhino/Grasshopper, Autodesk Fusion 360, and SolidWorks.
