The . Abstract This paper presents a novel approach for the interactive design of linear structures in space . A method is introduced , that provides a maximum of formal freedom in the design of funicular , hence efficient , structures . For a given deck ge - ometry , defined by a design driving NURBS curve via parametric modeling tech - niques , a tailored relaxation routine allows for controlled , real - time form - finding of the spatial funicular . Subsequently , the equilibrium of the deck is constructed using techniques from graphic statics , combined with a least - square optimization technique . Finally , the method is applied to a design example .
