This paper reexamines the interweaving method to demonstrate how architectural computation can reinterpret the advantages of this traditional crafting techniques for its geometrical compatibility and rule generativity. Firstly, the technique analyzes and reconfigures load distribution of a traditional interwoven surface to mimic its structural principle. Secondly, from this structural reconfiguration, the study applies parametric shape grammar to define interweaving rules.The rules generate various patterns with rigid local materials that fit the size of human hand.The experiment in this study shows that interweaving grammar can generate ornamental-structural components with three different load distributions, three different segmented materials and in three different spatial dimensions (point, line and plane).

While form-finding and optimization methods in shell structures have been widely advanced, discourses regarding an ideation process of how a designer or engineer may synthesize a precedent into novel designs have been less explored, as such ideation mainly relies on his/her intuition in representing structural problems. In this paper, we present a computational method to synthesize shell designs through the interplay between mechanical idealization and visual computation using traditional craft as a reference. Examples of how to generate a folding structure from weaving and tensegrity structure from folding show not only the way to convert craft logic from one type to another in shell structures but also the method to explicitly interpret the designer's ideation process in generating a certain structural design.
