A simple fabrication system for unfolding complex architectural surfaces

Abstract

In this research, we explore the implementation of panels with a single bending direction as cylindrical surfaces; in so doing, we present our ongoing research, focusing on finding ways to simply and affordably address the problem of constructability of double-curved structures. By encoding 3D freeform surface information into a 2D workflow, our in-house software (named UNFOLDING) breaks down complex mesh structures into a number of discrete and flat quadrilaterals that can be translated into a fabrication layout. UNFOLDING provides a practical way of linking the process of production and assembly to freeform architectural design. After introducing UNFOLDING in two design studios at Texas A&M University, freshman architecture students used laser-cut quadrilateral panels to design and construct several complex forms with positive or negative Gaussian curvatures.
