Parametric Design
Design Processes
Designing with rules and relationships, so changing one value updates the whole model.
In practice
Parametric design defines a form through parameters and the relationships between them — a shelf's depth drives its bracket size, a facade's panel count follows its curvature — so the design is a system that regenerates when an input changes rather than a fixed drawing. It is how one model becomes a family, and how late changes stop being expensive.
Questions
What is Parametric Design?
Parametric design is modelling a design as a set of variables and dependencies, so that altering any parameter propagates consistent changes through the entire form.
Why do you use Parametric Design?
It makes iteration nearly free and variation systematic. You design the logic once and explore a hundred outcomes.
How do you use/apply Parametric Design?
Identify what should drive the design, express the geometry in terms of those drivers in a parametric tool — Grasshopper, Fusion, code — and vary them to explore.
When do you use Parametric Design?
For product families, adaptable systems, complex geometry, and anywhere the brief is likely to change.
Who uses Parametric Design?
Industrial designers, architects and computational designers.
