The computation and construction of curved beams along freeform skins pose many challenges. Controlling the curvature of design surfaces and beam networks, and using the elastic behavior of material to shape these grids, opens up new strategies for fabrication-aware design. We show how to use surfaces of constant mean curvature (CMC) to compute beam networks with beneficial properties, both aesthetically and from a fabrication perspective. To explore variations of such networks we introduce a new discretization of CMC surfaces as quadrilateral meshes with spherical vertex stars. The computed variations can be seen as a path in design space – exploring possible solutions in a neighborhood, or represent an actual erection sequence by elastic transformation.
