summary	Building design is a process often divorced from considerations about construction. Digital design methods are increasingly challenging the historic relationship between architecture and its means of production, but this extended reach is not necessarily accompanied by extended understanding or leverage of the production process. We present an urban sculptural project, The Travellers, in which digital techniques resolved critical issues of design, documentation and fabrication, but more importantly facilitated highly beneficial processes of negotiation. We suggest that this case based research has implications for future interactions between designers, makers and managers, shedding additional light onto issues of negotiation, responsibility, risk and trust that are often critical to the pragmatic undertaking of making.

summary	This paper presents research on the relationship between digital tools and design communication, focussing on the interaction between architectural and lighting design. Early design integration often involves negotiating between different levels of resolution to inform a design that is still in formation, and part of the challenge is doing so in a manner appropriate to that phase of exploration. This paper describes some of the technical and social issues of translation and reports a project in which a generative design process supported the interaction between architectural design and lighting analysis; domains in which geometry is not necessarily a common ground.

title	Concepts and Methodologies for Multiscale Modeling: A Mesh-Based Approach for Bi-Directional Information Flows
doi	https://doi.org/10.52842/conf.acadia.2016.308
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 308-317
summary	This paper introduces concepts and methodologies for multiscale modeling in architecture, and demonstrates their application to support bi-directional information flows in the design of a panelized, thin skinned metal structure. Parameters linked to the incremental sheet forming fabrication process, rigidisation, panelization, and global structural performance are included in this information flow. The term multiscale refers to the decomposition of a design problem into distinct but interdependent models according to scales or frameworks, and to the techniques that support the transfer of information between these models. We describe information flows between the scales of structure, panel element, and material via two mesh-based approaches. The first approach demonstrates the use of adaptive meshing to efficiently and sequentially increase resolution to support structural analysis, panelization, local geometric formation, connectivity, and the calculation of forming strains and material thinning. A second approach shows how dynamically coupling adaptive meshing with a tree structure supports efficient refinement and coarsening of information. The multiscale modeling approaches are substantiated through the production of structures and prototypes.

title	Designing for Pedestrians : A CAD-Network Analysis Approach
source	New York: John Wiley & Sons, 1992. pp. 379-398 : ill. includes a short bibliography
summary	Microcomputer techniques have been developed that combine CAD drawings with transportation network analysis software that uses spreadsheets and stand-alone programs activated from the DOS operating system. The CAD feature simplifies and improves the methods used to design pedestrian circulation facilities and evaluate the impact of new development on existing pedestrian flows. Through the use of customized software, the need for manual data entry is reduced, and the graphical display of analysis results in most intermediate steps in the process are automated. Three hypothetical case studies are presented, concentrating on proposed pedestrian circulation improvements at Penn Station, New York

title	Automating the Drafting for As-Found Recording and Facility Management Surveys

source	Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 315-332
summary	Much of the time of a facility planner, restoration architect or heritage recorder is spent, on site analysing thebuilding and collecting data and measurements. These will be used later to create the reports and drawings that will provide the basis for the subsequent design but these notes and measurements are just the beginning of the long process of drafting the as-found situation. Errors are inevitable in this type of work but, typically they only come to light, back in the office where confirming a measurement may entail an extra trip to the site, and there are times that they only turn up when a contractor encounters problems on the job A software tool, currently under development, addresses this problem by first helping to structure the note taking process so that more consistent data is collected, and then, automatically creating a 2D or 3D CAD model from the resulting database. This can be done on a laptop computer, before the recording team leaves the site so that the model can be compared with reality and faulty or missing measurements corrected. Furthermore, this combination of database and drawing is linked, allowing queries of the data from inside Autocad or the assembly of a specialized model based on a database query. Point collection techniques supported include traditional and not so traditional) hand measurement, total station surveying equipment and interfaces with other software such as rectification and photogrammetric packages. The applications envisioned include as found recording, facilities management data collection and the possibility of a totally data-driven GIS

title	A Case Study in Teaching Construction of Building Design Spaces
doi	https://doi.org/10.52842/conf.ecaade.2013.2.595
source	Stouffs, Rudi and Sariyildiz, Sevil (eds.), Computation and Performance – Proceedings of the 31st eCAADe Conference – Volume 2, Faculty of Architecture, Delft University of Technology, Delft, The Netherlands, 18-20 September 2013, pp. 595-604
summary	Until recently, design teams were constrained by tools and schedule to only be able to generate a few alternatives, and analyze these from just a few perspectives. The rapid emergence of performance-based design, analysis, and optimization tools gives design teams the ability to construct and analyze far larger design spaces more quickly. This creates new opportunities and challenges in the ways we teach and design. Students and professionals now need to learn to formulate and execute design spaces in efficient and effective ways. This paper describes curriculum that was taught in a course “8803 Multidisciplinary Analysis and Optimization” taught by the authors at Schools of Architecture and Building Construction at Georgia Tech in spring 2013. We approach design as a multidisciplinary design space formulation and search process that seeks maximum value. To explore design spaces, student designers need to execute several iterative processes of problem formulation, generate alternative, analyze them, visualize trade space, and address decision-making. The paper first describes students design space exploration experiences, and concludes with our observations of the current challenges and opportunities.

doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_6
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	Co-creation and real-time collaboration have always been an integral potential of digital design methodologies and have been accelerated by the rapid digitalization of teaching due to current societal developments. This paper discusses the prototype of a real-time multiplayer building platform as a video game developed for a first-year design studio impacted by pandemic-related teaching restrictions. The aim was to develop a methodology that enables first-year students to meet peers, build models collaboratively, and teach implicit design knowledge such as aesthetics and formal analysis while allowing individual creativity within the populous class. Through a combination of a step-by-step iterative design system and a real-time decentralized multi-player platform, students can work collaboratively on common digital designs. The design method is based upon building units and individualized strategies of aggregation and differentiation that are built up into larger structures. Special focus is paid to how new online platforms created for architecture education can migrate the advantages of physical intuitive design methods to a digital setting and eventually fill the gap of lacking implicit knowledge pedagogies.

summary	The paper concerns the potential of sensors as architectural design tools in different spatial and temporal scales. In particular, the focus is on how sensors are able to operate in a constantly changing environment, and how sensors might nurture an intuition of otherwise non perceivable aspects of performance within architecture.The study discus two set-ups. Firstly; an onsite sensor reading of changing performance between a refurbished and a classic Arabic house; the study is in large spatial and temporal scale. Secondly; a model design setup where the performance of the same Arabic house typology is tested in small spatial and small temporal scale. The study shows how large scale architecture can be investigated through the use of sensor chaining and how simple sensors can be implemented in a design task in order to give insight to certain aspects of performance. The paper concludes with a discussion on a more general sensor strategy for changing environments and design setups.

title	Rectangular V-Splines
source	IEEE Computer Graphics and Applications. February, 1986. vol. 6: pp. 35-40 : ill. some col. includes bibliography
summary	This article describes and presents examples of some techniques for the representation and interactive design of surfaces based on a parametric surface representation that uses v-spline curves. These v-spline curves, similar in mathematical structure to B-splines, were developed as a more computationally efficient alternative to splines in tension. Although splines in tension can be modified to allow tension to be applied at each control point, the procedure is computationally expensive. The v-spline curve, however, uses more computationally tractable piecewise cubic curves segments, resulting in curves that are just as smoothly joined as those of a standard cubic spine. After presenting a review of v-splines and some new properties, this article extends their application to a rectangular grid of control points. Three techniques and some application examples are presented

title	The Use of New Media Tools in Environmental Simulation
source	Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary	Urban design model simulations serve to let us envision the future environment. These models are important tools in planning processes and serve to democratize improve the comprehension of decision processes. Those affected and (often) laypeople help in the formulation of opinions. Not lastly, model simulations facilitate the evaluation of the quality of the future urban design spaces and allow for corrections in the optimization of designs. Model simulations can be created by the help of endoscopic techniques already well known to medicine. Nowadays, virtual simulations can, on the other hand, be entirely created on a computer through the use of suitable programs. At the present time a comparative investigation into the performance capabilities of analog and digital technologies is still pending. In a two-group comparative study, static analog and digital simulations were compared by using categorical scales to answer questions on urban design layout and living space quality. The results demonstrated that analog and digital simulations lead to similar value judgments. However, layout and living space quality in the analog simulations were given somewhat higher rankings, on average. A conclusive statement about the performance capabilities of analog or digital simulations in urban design processes is still premature. Future studies should take this context into consideration. Aside from the performance capabilities of a simulation, other aspects are also to be considered, such as the resource requirements for practical urban planning processes. At this time the use of analog simulations is often recommended. This is because the use of analog simulations brings similar results using fewer resources than digital simulations. To the observer, analog simulations retain a more natural quality. Now as before, models are often constructed during the performance of urban design projects, reducing even further the resource demands of an analog model, which in the end is reflected in the costs.

summary	Flexible mass customization of buildings is still in its infancy. Current systems for the automated support of ownerdriven configuration management are limited with regard to the degree of freedom they offer to end-users, due to the lack of an easy way to specify those freedoms. In this paper we present the prototype of an interface that allows architects to define constraints to which user-customized dwellings must conform.

summary	Flexible mass customization of buildings is still in its infancy. Current systems for the automated support of owner-driven configuration management are limited with regard to the degree of freedom they offer to end-users. In this paper we present and discuss a constraint definition and verification system that allows the architect to specify boundary conditions within which the client can vary the design. The required constraint grammar is presented and applied to a real-world building code. A 2D floor plan prototype is tested to reveal the methodological and technical issues to be solved to make a step forward.

title	Plane-Sweep Algorithms for Intersecting Geometric Figures
source	Communications of the ACM. October, 1982. vol. 25: pp. 739-747 : ill. includes bibliography
summary	Algorithms in computational geometry are of increasing importance in computer-aided design, for example, in the layout of integrated circuits. The efficient computation of the intersection of several superimposed figures is a basic problem. Plane figures defined by points connected by straight line segments are considered, for example, polygons (not necessarily simple) and maps (embedded planar graphs). The regions into which the plane is partitioned by these intersecting figures are to be processed in various ways such as listing the boundary of each region in cyclic order or sweeping the interior of each region. Let m be the total number of points of all the figures involved and s be the total number of intersections of all line segments. A two plane-sweep algorithm that solves the problems above is presented; in the general case (non convexity) in time O((n+s)log-n) and space O(n+s); when the regions of each given figure are convex, the same can be achieved in time O(n log n +s) and space O(n)

summary	In the context of activity-based transport simulation models, multi-day activity planning is receiving increasing attention. The aim of this paper is to develop and illustrate an extension of a needs-based model of activity generation that takes into account possible influences of pre-planned activities and events. This paper describes the theory and shows the results of simulations of the extension. The simulation was done for six different activities and different parameter values. The results show that the model works well and the influences of the parameters are clear and seem logical.
