Parametric thinking

What this module covers

• Define a parameter, and distinguish independent from dependent ones
• Express geometry as rules rather than as coordinates
• Choose the parameters that matter and refuse the ones that do not
• Explain why a parametric model is a liability if nobody can read it
• Read a parametric sweep as a design tool rather than as a form generator

Lessons

1. 3.1

   What a parameter is

   Independent and dependent quantities, rules instead of coordinates, and why the choice of parameters is the design.

2. 3.2

   Parametric structures

   Generating grids, trusses, diagrids and tapered towers — and reading the numbers that come with them.
