Why do they say that hyperbolic paraboloids offer simplicity in design?
The hyperbolic paraboloid is the only three-dimensional shape that can be analyzed by simple statics, and this makes it easy to understand its structural action and to prepare plans. A hyperbolic paraboloid is made up of a series of straight lines side by side, as one can prove by moving a straightedge across it. This makes it possible to build forms for such shells by using straight lumber without fancy cutting.
