title	Towards Self-shaping Metamaterial Shells: A Computational Design Workflow for Hybrid Additive Manufacturing of Architectural Scale Double-Curved Structures
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_26
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	Double curvature enables elegant and material-efficient shell structures, but their construction typically relies on heavy machining, manual labor, and the additional use of material wasted as one-off formwork. Using a material’s intrinsic properties for self-shaping is an energy and resource-efficient solution to this problem. This research presents a fabrication approach for self-shaping double-curved shell structures combining the hygroscopic shape-changing and scalability of wood actuators with the tunability of 3D-printed metamaterial patterning. Using hybrid robotic fabrication, components are additively manufactured flat and self-shape to a pre-programmed configuration through drying. A computational design workflow including a lattice and shell-based finite element model was developed for the design of the metamaterial pattern, actuator layout, and shape prediction. The workflow was tested through physical prototypes at centimeter and meter scales. The results show an architectural scale proof of concept for self-shaping double-curved shell structures as a resource-efficient physical form generation method.

summary	This paper discusses Augmented Reality on smartphones as a tool for building complex structures without utilizing CNC technology while showcasing architectural research. A 1:1 prototype made of concrete blocks was built to test the current stage of this technology, along with an interactive virtual exhibition. Results showed a positive outcome regarding possibilities to use the accessible technology of smartphones as a complementary tool, both in the construction site and to computerize construction work nowadays. Despite tolerance issues in the placement of blocks, the technology proved effectful as a construction and visualization method.

title	Topology Generated Non-Fungible Tokens - Blockchain as infrastructure for a circular economy in architectural design
doi	https://doi.org/10.52842/conf.caadria.2021.2.151

summary	The paper presents a new digital infrastructure layer for buildings and architectural assets. The infrastructure layer consists of a combination of topology graphs secured on a decentralised ledger. The topology graphs organise non-fungible digital tokens which each represent and correspond to building components, and in the root of the graph to the building itself.The paper presents background research in the relationship of building representation in the form of graphs with topology, of both manifold and non manifold nature. In parallel we present and analyse the relationship between digital representation and physical manifestation of a building, and back again. Within the digital representations the paper analyses the securing and saving of information on decentralised ledger technologies (such as blockchain). We then present a simple sample of generating and registering a non-manifold topology graph on the Ethereum blockchain as an EC721 token, i.e. a digital object that is unique, all through the use of dynamo and python scripting connected with a smart contract on the Ethereum blockchain. Ownership of this token can then be transferred on the blockchain smart contracts. The paper concludes with a discussion of the possibilities that this integration brings in terms of material passports and a circular economy and smart contracts as an infrastructure for whole-lifecycle BIM and digitally encapsulates of value in architectural designPlease write your abstract here by clicking this paragraph.

title	KPI-Driven Parametric Design of Urban Systems
doi	https://doi.org/10.52842/conf.caadria.2021.2.579

summary	We present a framework for data-driven algorithmic generation and post-evaluation of alternative urban developments. These urban developments are framed by a strategic placement of diverse urban typologies whose spatial configurations follow design recommendations outlined in existing building and zoning regulations. By using specific rule-based generative algorithms, different spatial arrangements of these urban typologies, forming building blocks, are derived and visualized, given the aforementioned spatial, legal, and functional regulations. Once the envisioned urban configurations are generated, these are evaluated based on a number of aspects pertaining to spatial, economic, and thermal (environmental) dimensions, which are understood as the key performance indicators (KPIs) selected for informed ranking and evaluation. To facilitate the analysis and data-driven ranking of derived numeric KPIs, we deployed a diverse set of analytical techniques (e.g., conditional selection, regression models) enriched with visual interactive mechanisms, otherwise known as the Visual Analytics (VA) approach. The proposed approach has been tested on a case study district in the city of Vienna, Austria, offering real-world design solutions and assessments.

title	Comparative Study between 2D and 3D Digital Freehand Drawing Applied to the Architectural Design Process
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1065–1076
summary	This paper aims to discuss representative subjects, such as freehand drawing and its operational tools, which allow 2D sketching through graphic drawing tables, whereas virtual reality head-mounted displays are used for 3D sketches. A pilot project exercise was carried out in the building of the Centro de Divulgaçao Científica e Cultural (CDCC-USP), in Sao Carlos (SP - Brazil). As a result, this research presents a comparative chart that investigates the potential uses of these technologies in architecture teaching and in the act of designing. Moreover, this scenario includes the 360? image technology that presents itself as a vehicle of immersion and apprehension of space, having as a backdrop the unfoldings of social isolation arising from COVID - 19.

title	Automating Bi-Stable Auxetic Patterns for Polyhedral Surface
doi	https://doi.org/10.52842/conf.acadia.2021.380

summary	Bi-stable auxetic structures, a novel class of architected material systems that can transform bi-axially between two stable states, offers unique research interest for designing a deployable stable structural system. The switching behavior we discuss here relies on rotations around skewed hinges at vertex rotating connectors. Different arrangements of skewing hinges lead to different local curvatures. This paper proposes a computational approach to design the self-interlocking pattern of a bi-stable auxetic system that can be switched between flat and desired curved states. We build an algorithm which takes a target synclastic polyhedral surface as input to generate the geometrical pattern with skewing hinges. Finally, we materialized prototypes to validate our proposed structures and to exhibit potential applications.

title	Development of a Landscape Simulation System for Historical and Cultural Heritage of the Region
doi	https://doi.org/10.52842/conf.caadria.2021.2.489

summary	In this study, we developed a historical and cultural landscape simulation system for Fujisawa-juku, a post town of the old Tokaido road. A game engine was used to recreate the landscape of the past by referring to old documents to inherit the history and culture of the region. Subsequently, an enhanced system was developed for changing the representation of time, season, and weather, and another system was developed for recreating the landscape using Ukiyo-e-style rendering. The developed system was exhibited at permanent installations in public facilities and at community events, and feedback from users led to major updates to the system. With the new information, we reviewed the shape of the model of the spatial components of the system and updated it to be more accurate. The digital model of this system can be updated with information that is not possible in a real model, such as a diorama. We will generalize this system through the unitization of spatial components to create a platform for historical cultural landscape simulation systems that can be used in other regions.

summary	Academic papers are full of final drawings and diagrams but gloss over process work, “less glamorous” images, and the amount of time and labor behind a fi nal product. Certain skills and expertise cannot be taught but are instead collected from years of personal experience – a body of knowledge inaccessible to some unless passed on through e-mails, Zoom calls, or personal observations. When dealing with these seemingly esoteric topics, it becomes easy to feel isolated in the problems, failures, or questions that arise and cannot be easily accessed in academic journals or a simple Google search. Although exacerbated by the global pandemic’s mandates and shifts in the way work is done - this feeling is not new. The following pages record clay 3D printing research on a KUKA industrial robotic arm completed by two 5th year undergraduate architecture students. Through drawings, images, and text, this field note documents decisions, failures, messes, and successes compiled from a year of socially distanced learning, researching, and living.

title	Interoperability Between Agisoft Metashape and Autodesk Revit Software
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 855–865
summary	The 3D digital mapping to create models (Mesh) contributes to the documentation of the architectural heritage, by the accuracy of the details achieved. The documentation through Building Information Modelling (BIM) technologies is a current strategy to digitize the as-built information. Despite the potential for integrated use of these technologies, interoperability between them presents a gap involving complexity and operability in the work process. This research aims to investigate the interface and communication capabilities between Mesh models, generated by photogrammetry, and a BIM model, through the interoperability between Agisoft Metashape and Autodesk Revit software. By analyzing a new format for heritage documentation through digital technologies, using as object of study the façade of the Centro de Divulgaçao Científica e Cultural (CDCC-USP) in Sao Carlos, the results show that the joint use of technologies does not present great losses of information, unlike the techniques that are currently used.

title	Integration of Algorithm-Based Optimization into the Design Process of Industrial Buildings: A Case Study
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_17
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	Algorithm-based optimization is widely applied in many fields like industrial production, resulting in state-of-the-art workflows in the production process optimization. This project takes the cultural lag of conventional industrial architecture design as a motivation to investigate the implementation of algorithmbased optimization into traditional design processes. We argue that an enhanced way of architectural decision-making is possible. Current approaches use a translation of the whole design problem into a single, overly complicated optimization system. Contrary to that, this paper presents a novel workflow that defines precise design steps and applies optimizations only if suitable. Furthermore, this method can generate relevant results for factory planning design problems with contradicting factors, making it a promising approach for the complex challenges of i.e. resource-efficient building.

summary	Operating room design is a complex planning task. In order to jointly find the best solution, specialists from numerous professions are involved in the planning process, since e.g. equipment layout and airflow is crucial for optimal surgical procedures. For a better and more informed discussion, and thus better optimization and firm decisions, we have developed a method linking BIM (Building Information Modelling), VR (Virtual Reality), AR (Augmented Reality), CFD (Computational Fluid Dynamics) simulation, and a tangible user interface, so that freely configurable layouts can be tested interactively, be discussed, and optimized both in model and 1:1 scale already in early planning phases. This method has been applied to a hospital design with 33 new operating rooms, differing in sizes as well as layouts according to the different types of operations.

summary	Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

doi	https://doi.org/10.52842/conf.ecaade.2021.2.211

summary	Close-range photogrammetry, due to the possibilities offered by the technological evolution of acquisition tools and, above all, the relative original challenges posed to surveyors and the theory of measurements, deserve constant critical attention. The new opportunities to detect and represent reality are mostly focused on historical architecture, referring to consequent orders of magnitude and restitution scales. On the other hand, the formalization of relevant practices for very small objects is not frequently addressed. In recent tests carried out using two Dino-Lite handheld digital microscope models, polarized light digital microscopes generally used in medical and industrial fields, we proved the potential of using these imaging systems also for Cultural Heritage documentation, highlighting, however, some issues related to the depth of field and the consequent acquisition geometry. Therefore, this study aims to solve these problems, increasing the performance of microscopic photogrammetry by optimizing the acquisition procedures with the design of custom accessories for micro-photogrammetry (e.g. a calibrated plate). These developments will be carried out as part of a technology transfer agreement with the Dino-Lite company pointed to codify a protocol for high accuracy photogrammetric documentation of small artefacts.

summary	This article approaches the theme of digital collage as a technique of graphic representation in Architecture and Urbanism emerging in cyberculture. The main objective is to highlight the underlying logic of digital collage as a representation language of contemporary architecture and urbanism projects. From a methodological point of view, this article is the result of qualitative, exploratory and descriptive research. In addition to the literature review on collage as an artistic and architectural expression, and its incorporation into digital culture, a study of multiple cases was carried out, taking as empirical object the graphic production of ten architecture and urbanism offices from different parts of the world. Finally, it appears that digital collages are consistent with the hybrid contemporary reality and create new poetics capable of representing the semantic and communicative dimension of architecture and urbanism design.

title	A new Relation Matrix as a Fruitful Meta-Design Tool - How to overcome typological limits
doi	https://doi.org/10.52842/conf.ecaade.2021.1.295
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 295-302
summary	The use of meta-design tools to support the early stages of the design process is widely proven in literature. Among these tools, the adjacency matrix and the bubble diagram provided the various professionals involved - not only in the AEC sector - with some useful information mainly regarding the connection types between spaces and the sizing of their dimensions. With the evolution of design and the change of architectural aims (e.g. sustainability, refurbishment), it is not fruitful, especially related to complex buildings (e.g. hospital, airport), to manage spaces and their connections through the traditional Adjacency Matrix and its dual (Bubble Diagram). These tools, used as they were originally designed, do not consider other characteristics but basic topological ones and are still linked to 2D geometry. For this reason, this research aims to increase the unexplored design potential of these tools considering huge advances in building object representation and links with knowledge. The first research steps led to a 3D analysis capable of providing knowledge on the connections and adjacencies between spaces and its environments located on different floors. Therefore, we decided to define further goals, breaking limits of the "adjacency" concept for a more extendable and general concept of "relation" between spaces and environments.

summary	This article addresses the issue of the relationship between digital games and the development of spatial thinking. The research question is: how can digital games be used to contribute to the development of geometric and spatial skills and competencies, extremely necessary for contemporary architects and urban planners? The main objective is to highlight digital games as a possible and emerging educational resource in the era of digital culture. From a methodological point of view, the article is the result of qualitative and exploratory research, both bibliographical and empirical. The results presented, which are the result of a didactic experiment carried out with the game Minecraft, point to the adoption of digital games as powerful playful didactic tools capable of contributing to the exercise and development of spatial vision and geometric thinking in Architecture and Urbanism.

summary	Recent advances in Natural Language Processing (NLP) and Diffusion Models (DMs) are leading to a significant change in the way architecture is conceived. With capabilities that surpass those of current generative models, it is now possible to produce an unlimited number of high-quality images (Dhariwal and Nichol 2021). This opens up new opportunities for using synthetic images and marks a new phase in the creation of multimodal 3D forms, central to architectural concept design stages. Presented here are three methodologies of generation of meaningful 2D and 3D designs, merging text-to-image diffusion models Stable Diffusion, and DALL-E 2 with computational methods. These allow designers to intuitively navigate through a multimodal feedback loop of information originating from language and aided by artificial intelligence tools. This paper contributes to our understanding of machine-augmented design processes and the importance of intuitive user interfaces (UI) in enabling new dialogues between humans and machines. Through the creation of a prototype of an accessible UI, this exchange of information can empower designers, build trust in these tools, and increase control over the design process.

title	Towards a Configurable Hybridity in Historic Preservation and Design
doi	https://doi.org/10.52842/conf.ecaade.2021.2.293
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 293-302
summary	This paper fulfills the dual purpose of developing a systematic methodology for designing new constructions and adding to or revivifying existing buildings in historic neighborhoods and demonstrating an effective pedagogy in regard to historic preservation at the undergraduate level. A previously developed methodology for verifying and analyzing hybridity in architectural design is expanded as a foundation for designing an addition to a historic building in a famous urban context, i.e., a registered historic structure in the museum district of New York City. Shape grammar as a computational design methodology is used to analyze the historic fabric of the urban area and to create a configurable hybrid design that is both compatible with that context and reflective of the needs and design of the contemporary urban setting. The validity of shape grammar as a methodology for designing configurable hybrid constructions in historic neighborhoods and its effectiveness in relation to a teaching focus on historic preservation are considered through an analysis of projects from an upper-undergraduate-level architectural design studio. The students used the shape grammar methodology to analyze and understand historic contexts and features in order to generate new designs for the given context.

title	Towards a Free-form Transformable Structure - A critical review for the attempts of developing reconfigurable structures that can deliver variable free-form geometries
doi	https://doi.org/10.52842/conf.ecaade.2021.2.381
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 381-390
summary	In continuation of our previous research (Hussein, et al., 2017), this paper examines the kinetic transformable spatial-bar structures that can alter their forms from any free-form geometry to another, which can be named as Free-form transformable structures (FFTS). Since 1994, some precedents have been proposed FFTS for many applications such as controlling solar gain, providing interactive kinetic forms, and control the users' movement within architectural/urban spaces. This research includes a comparative analysis and a critical review of eight FFTS precedents, which revealed some design and technical considerations, issues, and design and evaluation challenges due to the FFTS ability to deliver infinite unpredictable form variations. Additionally, this research presents our novel algorithmic framework to design and evaluate the infinite form variations of FFTS and an actuated prototype that achieved the required movement. The findings of this study revealed some significant design and technical challenges and limitations that require further research work.

summary	When programming robotic assembly processes, it is often necessary to create a sequential list of actions. Some actions are robotic motions (requiring motion trajectory), and some are for controlling external equipment, such as grippers and fastening tools. The act of planning these actions and motion trajectories is called Task Planning and Motion Planning. Existing literature in robotics explored many different planning algorithms for planning a single trajectory to planning a complete sequence of tasks where continuity is maintained [Garrett et al, 2021]. Many application literature focused on the TAMP for service robots, medical robots, and self-driving cars, while there are few examples for architectural applications. For digital fabrication and automated construction, the planning method has to be adapted to the needs of architectural assemblies and the scale of construction [Leung et al, 2021]. Some of the unique challenges are the highly bespoke workpiece and assembly geometry, the large workpiece (e.g., long beams), and a dense collision environment. This three-day hybrid workshop addressed the needs of the architectural robotics community to use industrial robotic arms to assemble highly bespoke objects. The objects do not have any repetitive parts or assembly targets. The workshop leaders shared their experiences using industrial robots to construct large-scale timber structures. One of the most useful techniques is the recently published “Flowchart Planning Method,” where task sequence is planned using a flowchart, and motion trajectories are planned in a second pass [Huang et al, 2021].
