Parametric design

A design approach in which objects are defined by adjustable parameters (dimensions, angles, ratios) rather than direct geometric manipulation, allowing users to customize designs by changing numerical values without needing 3D modeling expertise. Parametric design is particularly valuable for assistive technology fabrication because therapists, educators, and end users can generate custom adaptive devices — such as grips, mounts, and holders — tailored to individual body measurements and functional needs by adjusting a few key fields, dramatically lowering the technical barrier to personalized AT creation through 3D printing.
