Parametric Design: When Math Meets Shape
Change one number. Reshape everything.
Change one number. Reshape everything.
A parameter is a number that controls part of a design. Instead of drawing a specific shape, you describe rules and let the parameters fill in the details. Adjust the sliders to see how one design produces many variations.
Constraints are relationships between parameters. "The inner circle is always half the outer circle." "The spacing is always equal." These rules keep the design valid no matter what values you choose. Adjust the bracket below and watch everything stay connected.
The holes are always evenly spaced and centered in the bracket, no matter the width or count.
Hole diameter is always 60% of the spacing. Change hole count and they automatically resize.
Corner radius cannot exceed half the height. The slider is clamped automatically.
Mathematical functions create complex patterns from simple equations. Click each pattern to see how a formula becomes a shape.
The Sagrada Familia cathedral in Barcelona was designed by Gaudi using parametric principles in the 1880s, long before computers. He hung chains upside-down to find the ideal arch shapes, then flipped the result.
From skyscrapers to jewelry, parametric design lets creators explore more options faster and produce forms impossible to design manually.
The Beijing National Aquatics Center, Zaha Hadid's buildings, and Norman Foster's Gherkin all use parametric design to generate organic, structurally optimized forms.
Phone cases sized to every model, chairs optimized for different body types, customizable jewelry. One parametric model serves thousands of customers.
Artists use parametric rules to create pieces that are different every time they run. The artist designs the system, and the system creates the art.
Topology optimization uses parameters to find the lightest structure that can bear a given load. The result often looks organic because nature solved the same problem.
You've discovered how a few parameters can generate infinite design variations. Instead of drawing every version by hand, you define the rules and let math do the rest.
Instead of fixed dimensions, use variables: height=H, width=W, radius=R. Change the variable, change the shape.
"The hole is always centered" or "the wall is 10% of the width." Constraints keep the design valid no matter what parameters you choose.
A parametric model is a recipe, not a single object. Feed in different ingredients (parameters) and get different results every time.
Sine waves make ripples. Fibonacci spirals make shells. Voronoi patterns make organic cells. Mathematical functions create forms no hand could draw.
