These models represent a method of joining structural members in multiple configurations. As a development of the "supple folds" enclosure concept, these connection nodes allow for several structural members to transfer load in almost any geometrical configuration. In order to facilitate the separation of disparate layers of building envelope, and to allow for complex and morphing structural geometries, a system of connecting was needed that was flexible and adaptable. These two examples illustrate a 1:2 condition and a 1:3 condition, where loads would either be distributed from a single member to multiple load paths, or from multiple members to a single path. In this instance, the nodes are constructed to receive structural members with a circular cross section, but the system for modeling the nodes could be easily modified to include a variety of alternate structural cross sections. The connection system could be quickly and easily constructed by exporting models of nodes built in maya to a cnc milling machine that would create a mold of the negative of the connector in two halves. The mold would then be used to cast the connectors in polyurethane. The models shown were created by converting the double-curved surfaces to a ruled surface geometry, exporting the maya file to rhinoceros, and unfolding each lofted surface to a flat plane. These planes were then printed, cut out and reassembled to form the physical model. This process is an approximation and required that the connectors be over-scaled by roughly 150%.
