Designing Fabric Structures

The first step in designing a fabric structure is to create a form with sufficient pre-stress, or tension, to prevent it from fluttering like a flag or sail. Lightweight structures with minimal surfaces optimally should have double curvature — a surface that possesses a high-point (positive) curvature along one principal axis and a low-point (negative) curvature along the other principal axis.

Anticlastic surface forms have double curvature in diametrically opposite directions, like a
