title	CubiGraph5K - Organizational Graph Generation for Structured Architectural Floor Plan Dataset
doi	https://doi.org/10.52842/conf.caadria.2021.1.081

summary	In this paper, a novel synthetic workflow is presented for procedural generation of room relation graphs of floor plans from structured architectural datasets. Different from classical floor plan generation models, which are based on strong heuristics or low-level pixel operations, our method relies on parsing vectorized floor plans to generate their intended organizational graph for further graph-based deep learning. This research work presents the schema for the organizational graphs, describes the generation algorithms, and analyzes its time/space complexity. As a demonstration, a new dataset called CubiGraph5K is presented. This dataset is a collection of graph representations generated by the proposed algorithms, using the floor plans in the popular CubiCasa5K dataset as inputs. The aim of this contribution is to provide a matching dataset that could be used to train neural networks on enhanced floor plan parsing, analysis and generation in future research.

title	From Design to the Fabrication of Shellular Funicular Structures
doi	https://doi.org/10.52842/conf.acadia.2021.328
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7].

summary	Shellular Funicular Structures (SFSs) are single-layer, two-manifold structures with anticlastic curvature, designed in the context of graphic statics. They are considered as efficient structures applicable to many functions on different scales. Due to their complex geometry, design and fabrication of SFSs are quite challenging, limiting their application in large scales. Furthermore, designing these structures for a predefined boundary condition, control, and manipulation of their geometry are not easy tasks. Moreover, fabricating these geometries is mostly possible using additive manufacturing techniques, requiring a lot of supports in the printing process. Cellular funicular structures (CFSs) as strut-based spatial structures can be easily designed and manipulated in the context of graphic statics. This paper introduces a computational algorithm for translating a Cellular Funicular Structure (CFS) to a Shellular Funicular Structure (SFS). Furthermore, it explains a fabrication method to build the structure out of a flat sheet of material using the origami/ kirigami technique as an ideal choice because of its accessibility, processibility, low cost, and applicability to large scales. The paper concludes by displaying a structure that is designed and fabricated using this technique.

summary	Space frames are widely used in spatial constructions as they are lightweight, rigid, and efficient. However, when it comes to the complex and irregular spaces frames, they can be difficult to fabricate because of the uniqueness of the nodes and bars. This paper presents a novel timber space frame system that can be easily manufactured using 3-axis CNC machines, and therefore increase the ease of the design and construction of complex space frames. The form-finding of the space frame is achieved with the help of polyhedral graphic statics (PGS), and resulted form has inherent planarity which can be harnessed in the materialization of the structure. Inspired by the traditional wood tectonics kerf bending and zippers are applied when devising the connection details. The design approach and computational process of this system are described, and a test fabrication of a single node is made via 3-axis CNC milling and both physically and numerically tested. The structural performance shows its potentials for applications in large-scale spatial structures.

title	Reusable Augmented Concrete Casting System - Accessible method for formwork manufacturing through holographic guidance

summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

title	An optimization method for large-scale 3D printing - Generate external axis motion using Fourier series
doi	https://doi.org/10.52842/conf.caadria.2021.1.683
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 683-692
summary	With the increase in labor costs, more and more robot constructions appear in building construction and spatial structure fabrication. There are many robots working on large-scale objects. When the reach range of the robot cannot meet the requirements, so an external axis is needed. The external axis is usually a linear motion device, which can significantly increase the operating range of the robotic arm. In actual construction, it is also widely used. This article introduces a 3d printing coffee bar project. Because this project is of a large scale and needs to be printed at one time, the XYZ external axis was used in this project to complete the task. Inspired by this project, this article study several methods of optimizing the motion of external axes in large-scale construction. Finally, we chose to use the Fourier series as the most suitable method to optimize the printing path and programed this method as a component of FUROBOT for more convenient use. This article explains the principle of this method in detail. Finally, this article uses a 3D printing example to illustrate the precautions in actual use.

summary	In usual robotic fabrication by 6-axis industrial robots such as KUKA, ABB, and other brands, the usual robot’s 4th, 5th, and 6th axis is exactly converged in one point. When this type robot (pieper) is doing movement commands, setting the degree of 4th axis close to zero is an ideal condition for motion stability, especially for putting device which connects to tool head on 4th axis arm part. In plastic melting or others print which not cares the rotation angle about the printing direction (the printing direction means the effector’s output normal direction vector, KUKA is X axis, ABB is Z axis), the optimization of 4th axis technology not only makes printing stable but also makes better quality for printing. The paper introduces a new algorithm to get the analytics solution. The algorithm is clearly explained by mathematics and geometry ways. At the end of the paper, a grasshopper custom plugin is provided, which contains this new algorithm, with this plugin, people can get the optimized target path plane more easily.

title	Visualizing Connections: Social Infrastructure at Two Brazilian Universities
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. 1089–1100
summary	Although often underrecognized, social infrastructures are a crucial ordering element in cities, as they are places or associations that shape the way people interact. We studied The Federal University of Rio de Janeiro (UFRJ) and the Federal University of Santa Catarina (UFSC) in three different diagrammatic approaches. An urban approach considered the relation between the institutions and their host cities, emphasizing the social infrastructure provision. A second analysis considered institutional activities, emphasizing how typological arrangements in which they occur. The third study focused on the UFSC campus and framed its social infrastructure through a systemic approach, focusing on the interactions between distinct community services and their distribution on campus. In addition to the diagrammatic emphasis allowing the interactions between the university and society to be clearly visualized, the results highlight a systemic disposition that reinforces the university as an urban entity and a crucial municipal and regional social support.

title	From Separation to Incorporation - A Full-Circle Application of Computational Approaches to Performance-Based Architectural Design
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_18
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	In performance-based architectural design, most existing techniques and design approaches to assisting designers are primarily for a single design problem such as building massing, spatial layouts, or facade design. However, architectural design is a synthesis process that considers multiple design problems. Thus, for achieving an overall improvement in building performance, it is critical to incorporate computational techniques and methods into all key design problems. In this regard, this paper presents a full-circle application of different computational design approaches and tools to exploit the potential of building performance in driving architectural design towards more novel and sustainable buildings as well as to explore new research design paradigms for performance-based architectural design in real-world design scenarios. This paper takes a commercial complex building design as an example to demonstrate how building performance can be incorporated into different building design problems and reflect on the limitations of existing tools in supporting the architectural design.

title	University Campus Walkability Index Supported by Digital Databases
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. 303–314
summary	Studies on the university campus commonly consider its spatial particularities in comparison to the city. However, the university debate about mobility also addresses urban-related challenges, like those posed by the dependence on vehicles and incentives for active mobility. Considering internal mobility, this work explores Wi-Fi connections from a Brazilian public university to trace community trajectories and population density on campus. We adopted objective data from the built environment for the application of a walkability index. The procedures were performed using GIS and the results shared for visualization in the Kepler.gl application. The results include walkability indices for different campus sectors. The discussion focuses on the potential use of the index in promoting a more integrated and less automobile-dependent campus.

summary	Social indicators are fundamental tools for measuring social facts, and their use has the potential to facilitate broad access to information. In 2020, the World experienced the beginning of the Coronavirus pandemic, which impacted the socio-spatial reality of cities around the world in several aspects and deepened social inequalities. As part of a coping Covid-19 project by ArqPET, the Somar Platform, this paper presents a mapping process of the spread of Covid-19 in Fortaleza during the four months after its arrival. The mapping, which aims to inform public policies and provides documents that support the demand for adequate housing and sanitary infrastructure in the neglected spaces of the city, relates the spread of the virus to social indicators and uses database technology to optimize its productions.

title	Inductive Creative Processes within Ideation Phases of Digital Design Products
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. 463–473
summary	This article aims to identify and analyze inductive aspects (those which go from particular instances to the general configuration) present in ideation phases of digital design projects (such as apps, websites and tools for companies’ internal communications), with special emphasis on how induction occurs in creative processes. Using a qualitative methodological approach, the analysis is based on in-depth, semi-structured interviews with digital designers, on a literature review on the subjects of creativity and classic design method, as well as on a design documentary. Research findings suggest the importance of combining the use of verbal and visual communication resources in group dynamics; the need for designers to be highly proficient in the tools and techniques used while generating new alternatives, regardless of their physical/analogical or virtual/digital nature; and to allocate, whenever possible, ample time to explore ideas in order to push the limits of each project being developed.

title	Application of 6-Dof Robot Motion Planning in Fabrication
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_31
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	. In practical robotic construction work, such as laying bricks and painting walls, obstructing objects are encountered and motion planning needs to be done to prevent collisions. This paper first introduces the background and results of existing work on motion planning and describes two of the most mainstream methods, the potential field method, and the sampling-based method. How to use the probabilistic route approach for motion planning on a 6-axis robot is presented. An example of a real bricklaying job is presented to show how to obtain point clouds and increase the speed of computation by customizing collision and ignore calculations. Several methods of smoothing paths are presented and the paths are re-detected to ensure the validity of the paths. Finally, the flow of the whole work is presented and some possible directions for future work are suggested. The significance of this paper is to confirm that a relatively fast motion planning can be achieved by an improved algorithmic process in grasshopper.

summary	On-site construction is one of the main research directions of robot construction. Due to the complex and everchanging construction environment on the site, traditional offline programming and simple conditional programming cannot meet the needs of robot on-site construction at all. Realtime adjustment of the robot's operating program for the real-time situation in the field is the appropriate solution. Therefore, the real-time communication and control of robots has become a key issue for robot on-site construction. This article discusses in turn the way of robot offline program control through EthernetKRL and grasshopper. A remote real-time communication and control method for an on-site construction robot is studied, and the application of the method in the on-site construction process of an actual robot is introduced with the Wuzhen coffee kiosk project as an example. Based on the above methods, remote real-time monitoring of the construction robot on site can be realized, which provides a reference for the actual engineering application of the construction robot on site.

title	Energy-Based Design: A Digital Design System for the Design of Energy-Harvesting Building Envelopes
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. 831–842
summary	The goal of the research described in this paper is to address climate change by promoting the production of renewable energy in building envelopes, which are exposed to solar radiation. It proposes an energy-based design paradigm, where energy processes shape the building form, and a digital design system for building envelopes that considers the trajectory of sunrays. The goal is to create envelopes that are efficient in harvesting solar energy, enabling them to produce the electricity that buildings consume. To operationalize the proposed digital design system, a building envelope grammar is developed and implemented in a software called LIDIA to be used by architects in design process to generate solutions with improved energy production performance. The efficiency of the resulting solutions, the effectiveness of LIDIA and, therefore, the validity of the proposed paradigm, is demonstrated with the design of envelope solutions for single family houses.

title	Diversifying Emotional Experience by Layered Interfaces in Affective Interactive Installations
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_21
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	This paper aims to improve users’ experience in affective interactive installations through the diversification of interfaces. With logically organized hierarchical experience, diverse interfaces with emotion data as inputs enhance users’ emotional interaction to be more natural and immersive. By using facial affect detection technology, an installation with diverse input interfaces was tested with an organic formal setting. Mechanical flowers and support structure based on the organic form were deployed as its physical output for a multitude of sensorial dimensions. With actions of the mechanical flowers, such as blooming, closing, rotating, glowing and blinking, a layered experiential sequence was created and the atmosphere of the installation was evaluated to be more engaging. In this way, the layered complexity of information was transferred to users’ immersive emotional experience. We believe that the practices in this work can contribute to deeper emotional engagement with users and add new layers of emotional interactivity.
