摘要

From Idea to Realisation, from "zero" to "one" in terms of scale, the way is always difficult. Many steps during this process. Papers of this Issue reflect some of them : the two first papers deal with computational methods that required successful algorithms, they develop innovative models (Wang and Ohmori, Kaveh andTalatahari). Realisation of projects requires other skills, namely when they use complex structural systems like those based on foldable systems (Lazaro and Domingo).
