summary	In this research, the authors discuss multiple design process criteria, fabrication methods, and assembly workflows for covering spaces using discrete pieces of material shorter than the space's span, otherwise known as topologically interlocking structures. To expand this line of research, the study challenges the interplay of geometric relationships in the assembly of unreinforced and mortar-less structures that work purely under compressive forces. This work opens with a review of studies concerning topological interlocking, a unique type of material and structural system. Then, through a description of two design projects - an interlocking footbridge and a vaulted structure - the authors demonstrate how they encouraged students to engage in a systematic exploration of the generative relationships among surface geometry, the configuration and formal variations of its subdividing cells, and the stability of the final interlocking assembly. In this fashion, the authors argue that there is hope for carrying the design criteria of topological interlocking systems into the production of precast concrete structures.

title	Breathable Walls - Computational Thinking in Early Design Education
doi	https://doi.org/10.52842/conf.caadria.2017.377
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 377-386
summary	This research categorizes the different breathable wall systems designed by students and describes their potential. Also included is a discussion of the results of both the physical analyses and digital simulations of these students' designs. To optimize the environmental performance of each proposed system, this work also engages in a more specific discussion of the advantages and limitations of these designs. Finally, this research concludes with a summary of the evidence of the benefits and risks of employing simulation tools in architecture studios.

title	A Simple Fabrication System for Unfolding Complex Architectural Surfaces
doi	https://doi.org/10.52842/conf.caadria.2017.767
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 767-776
summary	In this research, we explore the implementation of panels with a single bending direction as cylindrical surfaces; in so doing, we present our ongoing research, focusing on finding ways to simply and affordably address the problem of constructability of double-curved structures. By encoding 3D freeform surface information into a 2D workflow, our in-house software (named UNFOLDING) breaks down complex mesh structures into a number of discrete and flat quadrilaterals that can be translated into a fabrication layout. UNFOLDING provides a practical way of linking the process of production and assembly to freeform architectural design. After introducing UNFOLDING in two design studios at Texas A&M University, freshman architecture students used laser-cut quadrilateral panels to design and construct several complex forms with positive or negative Gaussian curvatures.

title	Kerfing with Generalized 2D Meander-Patterns: Conversion of Planar Rigid Panels into Locally-Flexible Panels with Stiffness Control
source	Gülen Çagdas, Mine Özkar, Leman F. Gül and Ethem Gürer (Eds.) Future Trajectories of Computation in Design [17th International Conference, CAAD Futures 2017, Proceedings / ISBN 978-975-561-482-3] Istanbul, Turkey, July 12-14, 2017, pp. 276-293.
summary	In this paper, we present a kerfing (relief-cutting) method to turn rigid planar surfaces into flexible ones. Our kerfing method is based on a generalization of the 2D meander-pattern recently invented by Dujam Ivaniševiæ. We have developed algorithms to obtain a large subset of all possible 2D meander-patterns with a simple remeshing process. Our algorithm can be applied to any polygonal mesh to produce 2D meander-patterns. The algorithm, when applied to regular (4,4) tiling pattern, in which every face is 4-sided and every vertex is 4-valence, provides the original 2D meander-pattern of Ivaniševiæ. Moreover, since these meander-patterns are obtained by a remeshing algorithm, by changing parameters, we can control local properties of the pattern with intensity of images to obtain desired stiffness in any given region (See Fig.1). This approach provides a simple interface to construct desired patterns.
