title	CAMBRIA: Interacting with Multiple CAD Alternatives

summary	Computer-aided design (CAD) tools aim to assist designers in their professional work, one key aspect of which is devising, evaluating, and choosing among multiple design alternatives. Yet, with few and limited exceptions, current tools handle just a single design model at a time, forcing users to adopt various ad hoc tactics for handling multiple design alternatives. Despite considerable prior work, there are no general, effective strategies for supporting design alternatives. New tools are needed to develop such strategies: to learn how designers’ behavior changes with support for multiple alternatives. In this article, we describe CAMBRIA, a multi-state prototype tool we developed for working with multiple 2D parametric CAD models in parallel. We describe the outcomes of an analytical evaluation of CAMBRIA using the Cognitive Dimensions framework.

title	Juxtaposed Designs Models: A Method for Parallel Exploration in Parametric CAD
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. 402-412.
summary	Computational tools mainly support authoring single-state models, which fall short in enabling designers to work with multiple solutions side-byside. This is a natural design behaviour commonly observed when designers use other media or improvise digital tools to explore alternatives. In this paper we attempt to formalize a method that aims to help designers to create multiple design alternatives derived from a base parametric model and its controllers. The goal is to change alternative designs such that each alternative can respond to changes as their internal structures allow. We present five assumptions on the tools that this can be achieved and also a parametric design pattern to be used in similar situations. Despite the complexity of the models, we can demonstrate the possibility of working with multiple solutions in architectural design.

title	Integrated Algorithmic Design - A single-script approach for multiple design tasks

summary	Many great architectural endeavors today engage in a multi software approach, as each specialty involved needs a different software, and different task required from the architect, such as 3D modeling, analysis or rendering, also benefit from the use of different tools. Combining them in the same process is not always a successful endeavor. A more effective portability mechanism is needed, and Algorithmic Design (AD) has the potential to become one. This paper explores the advantages of the algorithmic approach to the design process, and proposes a methodology capable of integrating the different tools and paradigms currently used in architecture. The methodology is based on the development of a computer program that describes not only the intended model, but also additional tasks, such as the required analysis and rendering. It takes advantage of CAD, BIM and analysis tools, with little effort when it comes to the transition between them.

title	Fabricating Without CAD Models - Experiments with G-code and KUKA KRL
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. 883-892
doi	https://doi.org/10.52842/conf.caadria.2017.883
summary	This research focuses on the transformation from design to fabrication without CAD models. In contrast to the conventional "design - modeling - fabrication" workflow, which involves multiple software, we experimented with a method of programming the bespoke fabrication process, and consequently defining the artifact. Algebraic models are employed to specify the materialization process carried out by various CNC machines. We used the programming language Java to create machine instructions for 3D printers, milling machines, and robots. In this method, design and production are not two separated processes; rather we regarded them as two aspects of one whole activity. Proficiency in machines and materials could contribute to design innovation.

title	Intuitive and Effective Gestures for Conceptual Architectural Design: An Analysis Of User Elicited Hand Gestures For 3D CAD Modeling
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 318- 323
doi	https://doi.org/10.52842/conf.acadia.2017.318
summary	Gesture-based natural interfaces necessitate research into gestures that are intuitive for designers and effective for natural interaction. Intuitive knowledge is significant for conceptual design as it reduces time taken to complete tasks and improves usability of products. In a previously conducted experiment, we elicited gestures for 3D CAD modeling tasks for conceptual architectural design. In this study, we present a preliminary analysis of intuitiveness scores of gestures and evaluators’ ratings to analyze which gestures were more intuitive and effective for CAD manipulation tasks. Results show that gestures with high intuitive scores were not necessarily rated as effective by evaluators and that bimanual symmetric gestures consistently scored high for both intuitiveness and effectiveness. Based on our findings we give recommendations for the design of gesture-based CAD modeling systems for single and multiple users.

title	Decoding Parametric Design Data - Towards a Heterogeneous Design Search Space Remix
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. 117-126
doi	https://doi.org/10.52842/conf.caadria.2017.117
summary	Designers or Non-Designers are not able to effectively access, view, search, discover, collect, reuse, remix and share parametric design data (PDD) for either professional or educational purposes. PDD here refers to the meta-data of 3D models generated by visual dataflow modelling software packages used in CAD/CAM industry. This ineffectiveness is a direct consequence of the deliberately proprietary nature of most PDD file formats and the restricted use within their respective desktop-based software environments. This paper presents an initial software prototype capable of automating the process of decoding a commonly used PDD file format and then re-encoding it with new set of metrics to facilitate multiple PDD searchability, comparability and interoperability, via an integrated web interface querying a design data repository. All PDDs are conceptualized as genealogies of numerical or geometric transformations and explicitly encoded with a graph-based data structure. The goal is to eventually learn from its own big data and begin to artificially generate novel PDDs heterogeneously.

summary	Designers work by creating alternatives. Current design media restrict this practice through their near-universal adherence to a single-state document model. We describe the implementation of an online gallery system built as part of a research program to understand new media types for working with design alternatives in parametric modeling. The online gallery supports multiple commercially available parametric modelers. A user study shows a significant difference between two modes of gallery operation and a qualitative study describes user patterns in using the online gallery system.

title	Polymorphic Adaptation

summary	Polymorphism, the ability of a substance to exist as multiple, different, crystalline solids is a subject of much interest in the fields of chemistry, pharmacy and crystallography. In some cases, polymorphs can be found to interconvert, usually in response to changes in the physical environment such as changes in temperature or pressure. The ability of structures composed of identical building blocks to interconvert is relevant to the field of architecture where architectural artefacts may require to respond to transient demands. Here we describe the phenomenon of polymorphism and the relevance to the architectural field, together with the development of a bespoke software plugin to allow polymorphic crystal structures to be used in design.

title	Plug-In Design - Reactivating the Cities with responsive Micro-Architectures. The Reciprocal Experience
source	Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 2, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 571-580
doi	https://doi.org/10.52842/conf.ecaade.2017.2.571
summary	Every city has under utilized spaces that create a series of serious negative effects. Waiting for major interventions, those spaces can be reactivated and revitalized with soft temporary projects: micro interventions that light up the attention, give new meaning and add a new reading to abandoned spaces. We can call this kind of operations "plug-in design", inheriting the term from computer architecture: interventions which aim to involve the citizens and activate the environment, engage multiple catalyst processes and civil actions. Plug-in design interventions are by all meanings experimental, they seek for interaction with the users, locally and globally. Information Technology - with its parametric and site-specific capabilities and interactive features - can be instrumental to create such designs and generate a new consciousness of the existing environment. With this paper we will illustrate how two low-budget interventions have re-activated a forgotten public space. Parametric design with a specific script allowing site-specific design, materials and structure optimization and a series of interactive features, will be presented through Reciprocal 1.0 and Reciprocal 2.0 projects which have been built in 2016 in Italy by the nITro group.

title	APART but TOGETHER - The Interplay of Geometric Relationships in Aggregated Interlocking Systems

doi	https://doi.org/10.52842/conf.ecaade.2017.1.639
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.

doi	https://doi.org/10.52842/conf.caadria.2017.633
summary	Algorithmic BIM combines BIM and Generative Design (GD), merging the potentialities of both approaches. In this paper we describe the design process of a set of parametric facades developed using Algorithmic-BIM, and how this approach was integrated into the design workflow of two architectural studios. We demonstrate how the integration of GD together with BIM influenced the whole design process and also the selection of the final solution. Some of the limitations found during the entire process are also addressed in the paper, such as tight deadlines and financial constraints. Finally, we explain the pros and cons of using this design method compared to a traditional BIM approach, and we discuss the implementation of this paradigm in a traditional design practice. This work was developed using Rosetta, an IDE for Generative Design that supports scripts using different programming languages and allows the generation and edition of 3D models in a variety of CAD and BIM applications. The result of this work is an information model of three parametric facades for a residential building, from which we can extract material quantities and construction performance tests.

title	Digital fabrication with Virtual and Augmented Reality for Monolithic Shells

doi	https://doi.org/10.52842/conf.ecaade.2017.2.211
summary	The digital fabrication of monolithic shell structures is presenting some challenges related to the interface between computational design and fabrication techniques, such as the methods chosen for the suitable parametrization of the geometry based on materiality characteristics and construction constrains, the digital optimization criteria of variables, and the translation of the relevant code used for digital fabrication. Specifically, the translation from the digital to the physical when a definite materiality appears during the digital fabrication process proves to be a crucial step, which is typically approached as a linear and predetermined sequence. This often-difficult step offers the potential of embedding a certain level of interactivity between the fabricator and the materialized model during the fabrication process in order to allow for real time adjustments or corrections. This paper features monolithic shell construction processes that promote a simple interface of live interaction between the fabricator and the tool control during the digital fabrication process. The implementation of novel digital and physical methods will be explored, offering the possibility of being combined with automated fabrication actions controlled by real time inputs with virtual reality [VR] influenced by 3d scanning and 3d CAD programs, and the possibility of incorporating augmented reality [AR].

doi	https://doi.org/10.52842/conf.acadia.2017.178
summary	The research presented in this paper seeks to examine how architecture and computational tools can be used to communicate on multiple levels by incorporating a series of qualitative and quantitative measures as criteria for a spatial and architectural design. Air is taken as a material that has the capacity to create boundaries, yet unless under extreme conditions often remains invisible. Varying in qualities such as temperature, humidity and pollution, the status of air is highly local to a particular context. The research explores how rendering air visible through an architectural intervention made of networked sentient prototypes can be used in the reation of a responsive outdoor public space. Although humans' ability to perceive and respond to stimuli is highly advanced, it is nevertheless limited in its spectrum. Within the urban context specifically, the information, material and flux being produced is becoming ever more complex and incomprehensible. While computational tools, sensors and data are increasingly accessible, advancements in the fields of cognitive sciences and biometrics are unraveling how the mind and body works. These developments are explored in tandem and applied through a proposed methodology. The project aims to negotiate the similarities and differences between humans and machines with respect to the urban environment. The hypothesis is that doing so will create a rich output, irreducible to a singular reading while heightening user experience and emphasizing a sense of place.

doi	https://doi.org/10.52842/conf.ecaade.2017.2.657
summary	This paper examines the current state of the conventional Design-Bid-Build project, wherein design intentions are manually translated to construction directives by subcontractors based on industry-specific details. This process exacerbates a dilemma in design and construction; that often the designer may be unaware of certain details that are involved in fabricating and assembling building components. Research for Knowledge Base for Architectural Detailing (KBAD) proposes a system that takes advantage of current CAD software and programming language, bringing together the information provided by and important to the design team with the data required by the subcontractor to accurately produce architectural components, during the design phases of a project. The trade of architectural precast concrete is used to demonstrate the potential of such a system. Solid modeling, visual scripting, and programming language techniques working towards KBAD are described. Possible variations of architectural precast concrete panels, detailed with window openings, reveals, and embed plates, are presented.

doi	https://doi.org/10.52842/conf.ecaade.2017.2.193.2
summary	Recent developments in digital design and fabrication tools have led architects and researchers to renew the interest in stereotomy. This interest converges with a growing ecological and economical conscience that matches classic stereotomy raw material needs: compression resistance materials. However, material resources or prefabrication time are still major counterparts for the adoption of this construction system. This paper focuses in exploring techniques that profit from the interdependency between built form and fabrication technique, foraging methodologies that allow for stereotomic block creation with simpler resources. The premise is to explore faster, cheaper, more accessible ways to build stereotomic structures. The technique developed in this research explores alternatives to the traditional cutting of stone by expanding techniques for variable moulds to form solid voussoirs.

summary	The use of daylight for the inhabitants health and comfort purposes and for the energy efficiency of buildings influences significantly the shape and outlook of urban environments. The solar envelope and solar collection surface are methods to define the massing of buildings for direct solar access requirements. They have been recently improved to be used in the design of buildings in relation to the Estonian daylight standard. Nevertheless the solar collection method can be applied only to single buildings with simple shape. The present research investigates the direct solar access performance of building clusters with multiple layouts in different urban areas in the city of Tallinn. Result show that different patterns perform in significant different ways whereas the same cluster types have the best and the least performances in all the cases.

doi	https://doi.org/10.52842/conf.ecaade.2017.1.485
summary	In emerging countries there is a need for rapid urban planning, since they are confronted by unprecedented wave of urbanization. This need is even bigger since usually there is no adequate number of professional educated urban planners in these countries. Therefore, we investigate in this paper how to develop a set of methods that allow to generate urban fabric semi-automatically. The challenge is to come up with a generative planning model that adapts to multiple boundary conditions.Through a modular design strategy generative methods are applied by students in an urban design studio in order to combine them into more complex planning strategies for small cities in the emerging country of Ethiopia. The modular approach allows to break down planning into sub-issues to better deal with the overarching problem. For testing the implemented generative urban design strategies various cities are generated at different locations in Ethiopia with various topographic situations. Their underlying design strategies and modular approach are discussed in this paper.

summary	This study focuses on generating geometric design alternatives for an airport roof structure with an evolutionary design method based on optimizing solar heat gain and daylight levels. The method incorporates a parametric 3D model of the building, a multi objective genetic algorithm that was linked with the model to iteratively test for various geometric solutions, a custom module that was developed to simulate solar conditions, and external energy simulation environments that was used to validate the outcomes. The integral outcome was achieved through an iterative workflow of many software tools, and the study is significant in dealing with several space typologies at the same time, taking real-life constraints such as applicability, ease of operation, construction loads into consideration, and satisfying design and aesthetic requirements of the architectural design team.

title	Understanding Cognitive Overload in Generative Design - An Epistemic Action Analysis
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. 127-136
doi	https://doi.org/10.52842/conf.caadria.2017.127
summary	Choice overload is experienced when designers use generative systems to explore a large number of alternatives. In an experiment, we studied the epistemic actions designers perform to reduce their cognitive load caused by possible choice overload during design exploration. The participants were asked to select alternatives among a large set of solutions in a simulated design environment. For data encoding, we adapted an epistemic action analysis method to understand which actions occurs in what phase of design. Most epistemic actions are observed during criteria applying phase. The most frequent actions were 'clustering and grouping' and 'talking and gestures to guide attention'. Ultimately our goal is to answer if a system can alleviate the possible cognitive overload when working with a large number of alternatives, if so how they would look when implemented.

summary	In the context of stereotomic practice, advanced fabrication with waterjet and wire-cutting of interlocking wave geometry has opened up new possibilities for crafting stone modules with precision and efficiency. This paper discusses the utilization of machined cutting techniques, the processes and workflows of fabricating joint systems for arched and vaulted surface geometries. It presents a comparative study with multiple criteria; such as geometry, method, material, machine and workflow. Furthermore, this paper presents research into the comparison between abrasive waterjet cutting and wire cutting of modules in stone and foam.
