Kajian Sketsa Digital dalam Proses Reka-Struktur Bentuk-Bentuk Surface
Abstract
Free form surface has a multiple complexity curve intrinsically, so that special approach is needed to form the structure. Geodesic shell is well-known as the shortest path between two points on a curved surface. This method is used to generate the structure of form, which can be easily determined by its basic shape or the complex form. This paper explains how Geodesic theory can assist to generate structures in the early stage of digital sketching. A workshop that has initially started becomes a topic to this discussion. The digital sketching process to apply the theory is the aim of this paper.

This book examines the possibilities emerging for design and architecture by the introduction of novel computer-aided design (CAD) and digital manufacturing techniques. The form studies show the translation of digitally conceived structures into 1:1 physical prototypes.
The constructs shown here do not pretend to be perfect finalized objects; they are to be seen as experiments with generative CAD tools, algorithms, and scripting applications, although some of the outcomes look like they are ready to be put into mass production.
The insights which arose from these experiments are presented and organized within five production techniques: cross segmentation, accumulation, frameworks, loops, and folding.
This paper describes a precise geometric method for the inscription of
structural constraints into architectural form. Based on techniques from graphic statics, the force distribution in building structures is visualized using geometric diagrams. This diagrammatic representation allows a formal description that shows the relationship between the force flow and the structural form. The formal character of this description enables the direct implementation of a parametric
truss geometry that maintains major structural behavioral characteristics under deformation. An interactive model of a structural freeform roof is developed through this link between a parametric truss definition and a design-driving NURBS surface. This allows for an intuitive exploration of the constrained design space in real time. Formal explorations and the comparison with built examples
demonstrate the effectiveness of this approach.
