title	Sewing timber panels: An innovative digitally supported joint system for self-supported timber plate structures

summary	This paper focuses on the joint system of flat panels as parts of a freeform building. This topic is a key area of the ongoing founded research project, in which we investigate nonstandard shapes, realized with standard building materials, namely cross-laminated timber (CLT). We use different discretization algorithms to overlay arbitrary freeform surfaces with ornaments consisting of polygonal flat panels. We investigate a series of ornaments and their discretization results on different surfaces. In this paper, we will present and discuss a new timber-to-timber joint system that we developed exclusively for this project. We discuss the results of the load tests that we performed recently and we take a look at the construction dependent requirements of the joint system concerning the tolerances and the geometry and also, how these constraints inform the digital process. As we will discuss throughout the paper, in earlier publications we described the form finding process and the geometrical guidelines for the discretization of a desired freeform building using ornamental flat patterns. This paper moves one step further as the digital becomes physical and it is closely related to building construction and the computational design outset.

title	Ornamental discretisation of free-form surfaces: Developing digital tools to integrate design rationalisation with the form finding process
doi	https://doi.org/10.52842/conf.caadria.2012.347

summary	The adoption of digital planning methods has given rise to an unprecedented formal freedom in architectural design. Free-form shapes enjoy considerable popularity in architectural production today. However, these shapes prove to be notoriously hard to fabricate. This paper reports on an ongoing research project investigating the approximation of continuous double-curved surfaces by discrete meshes consisting solely of planar facets, which can be constructed efficiently by using standardised, mass-produced building materials. We introduce our geometrical approach, which is based on the intersection of tangent planes to the surface, and present the digital tools we conceived to integrate the processes of design rationalisation and form-finding.
