This is the earliest method developed for shaping fabric. Because fabric is soft, difficult to control, and unable to stand on its own, it requires an added skeletal structure to improve its controllability. In this approach, a planar frame is added to the fabric as a boundary “bone,” and by connecting predetermined nodes, the fabric can be deformed from a flat surface into a three-dimensional form. The overall structure also gains sufficient strength to stand independently. This series of square-frame designs later became the prototype for the Tension Module forming method.

這是為布料造型所最早思考的手法。布料本身柔軟不易控制形態且不能自力，需要爲其增添骨骼才可以增强其可控性。這個手法是在布料上增添平面形狀的邊框骨架，然後連接預設的節點，就可以使布料產生從平面到立體的變形。并且整體結構具有了自立的强度。這一系列方形邊框的設計，也是張拉模塊造型手法的雛形。
