The design of free-form structures is a complex process governed by structural performance and cost of fabrication. This last aspect is described by geometrical properties of a mesh, generally made out of quadrangles. These properties are known from a theoretical point of view, but the designers generally lack tools or knowledge to quickly generate inherently good panelization or structural layouts. Moreover, little has been done on node repetition in free-form structures. In this paper, the authors present a new family of shapes that exhibit high node congruence and are optimal with respect to the most common geometrical optimization targets. The properties of these meshes, named isogonal moulding surfaces by the authors are discussed, and some examples are shown.
