title	BIM and the Building Site: Assimilating digital fabrication within craft traditions
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 27-36
summary	This paper outlines a particular component of very well known project: Antoni Gaudí’s Sagrada Família Basilica in Barcelona (1882– on-going but scheduled for completion in 2026). At the time of writing the realisation of the project has proceeded for 87 years since Gaudí's death (1852-1926). As a building site it has been a living laboratory for the nexus between traditional construction offsite manufacturing and digital fabrication since the computers were first introduced to the project:CAD in 1989 closely followed by CAAD two years later. More remarkably CAD/CAM commenced its significant influence in 1991 with the take-up of sem robotised stone cutting and carving. The subject of this paper is an elevated auditorium space that is one of the relatively few ‘sketchy’ areas that Gaudí bequeathed the successors for the design of his magnum opus.

title	Leaving the Planar Universe
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 521-534
summary	A computer program is presented which generates realistic images of planned buildings embedded in their future environment through photomontage. The planar universe of conventional photomontaging is extended to three dimensions. During an interactive preprocessing step, a three- dimensional model of the building's environment is created: Geometrical data is retrieved photogrammetrically from a number of site photographs. Atmospheric parameters and the relative weights of the components of natural daylight are also retrieved from the photographs. The final image, combining the artificial model of the building and the photographs of its surroundings, is rendered by an extended ray-tracing algorithm in three-dimensional object space.

title	ABLOOS : an evolving hierarchical design framework
source	Carnegie Mellon University, Department of Architecture
summary	The research reported in this thesis develops an approach toward a more effective use of hierarchical decomposition in computational design systems. The approach is based on providing designers a convenient interactive means to specify and experiment with the decompositional structure of design problems, rather than having decompositions pre-specified and encoded in the design system. Following this approach, a flexible decomposition capability is combined with an underlying design method to form the basis for an extensible and evolving framework for cooperative (humdcomputer) design. As a testbed for this approach, the ABLOOS framework for layout design is designed and constructed as a hierarchical extension of LOOS.’The framework enables a layout task to be hierarchically decomposed, and for the LOOS methodology to be applied recursively to layout subtasks at appropriate levels of abstraction within the hierarchy; layout solutions for the subtasks are then recomposed to achieve an overall solution, Research results thus far are promising: ABLOOS has produced high quality solutions for a class of industrial layout design tasks (an analog power board layout with 60 components that have multiple complex constraints on their placement); the adaptability of the framework across domains and disciplines has been demonstrated; and, further development of ABLOOS is underway including its extension to layouts in 2 1/2D space and truly 3D arrangements. The contribution of this work is in demonstrating an effective, flexible and extensible capability for hierarchical decomposition in design. It has also produced a more comprehensive layout system that can serve as a foundation for the further investigation of hierarchical decomposition in a variety of design domains.

title	Grids in Design and CAD
source	Reality and Virtual Reality [ACADIA Conference Proceedings / ISBN 1-880250-00-4] Los Angeles (California - USA) October 1991, pp. 33-43
doi	https://doi.org/10.52842/conf.acadia.1991.033
summary	The grid is a useful device for expressing design rules about the placement of elements in a layout. By expressing position rules for elements in relation to a grid, a designer can systematically organize decisions in a layout design problem. Grids and placement rules offer a discipline that can help a designer work effectively to lay out complex designs, and it can also facilitate group design work. Unfortunately, computer supported drawing systems often cannot support this way of working because they lack a sufficiently rich implementation of grids. The Grid Manager module of the CoDraw program shows enhancements useful for architectural Computer Assisted Design. These enhancements would enable more effective ways of using the computer as a design tool.

summary	A procedure for generating 3-dimensional spatial configurations for optimization applications, termed Dimension Constrained Rectangular Voronoi Diagram (DC-RVD), is presented in this paper. The procedure is able to generate a non-overlapping configuration of spatial units in 3-dimensional space, given a string of real values. It constitutes an extension and adaptation of the Rectangular Voronoi Diagram generating procedure, found in the work of Choi and Young (1991). An extensive description of the procedure, with the relevant pseudocode is included in the paper. The procedure is tested in a stochastic optimisation-based decision support environment. Testing is done using a case study of a medium-sized family house. The result indicate promising performance.

title	EVALUATION OF THE OSLD HOUSING SYSTEM
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	In the production of low-income housing, one of the factors that most affects the low cost of each unit is its mass production. When it comes to building a proposed design it must have been sufficiently studied and evaluated. When designing low-income housing it is convenient to exhaust all the possibilities of simulation in order to produce a prototype that, once built, has reduced the risk of errors. Simulations allow to improve the prototype before proceeding to build it. The Real Scale Model (RSM) has proved to be a better simulation tool than computer generated models or 1:10 scale models. It allows to reproduce and evaluate perceptual experiences as well as being user friendly because most of the spatial variables can be represented. This research is another example of the use and effectiveness of the RSM in the field of design and architectural research. A Real Scale Model of the basic unit was built by the students of the course Spatial Design Ability dictated by the LEE. The model was first evaluated empty and then a furnishing solution was proposed, built and evaluated. These evaluations were done by another group of students of the Faculty of Architecture and Planning using the Psychological Impressions Measuring Test (IMIP) developed by Luis La Scalea (1991). This test was designed to measure people’s psychological impressions produced by a space, and consists of a semantic differential structured by eleven pairs of opposing adjectives set on a scale of seven levels. The results of this first evaluation were analysed used to modify the prototype which was evaluated again in order to produce a final layout.

summary	To begin with, I would like to say a few words about the problem of alienation of modern technologies which we also inevitably faced while starting teaching CAD at our department. Quite often nowadays a technology becomes a fetish as a result of lack of clear goals in human mind. There are multiple technologies without sense of purpose which turned into pure experiments. There is always the danger of losing purposeness and drifting toward alienation. The cause of the danger lies in forgetting about original goals while mastering and developing the technology. Eventually the original idea is ignored and a great gap appears between technical factors and creativity. We had the danger of alienation in mind when preparing the CAAD curriculum. Trying to avoid the tension between technical and creative elements we agreed not to introduce CAD too soon then the fourth year of studies and continue it for two semesters. One thing was clear - we should not teach the technique of CAD but how to design using a computer as a medium. Then we specified projects. The first was called "The bathroom I dream of" and meant to be a 2D drawing. The four introductory meetings were in fact teaching foundations of DOS, then a specific design followed with the help of AutoCAD program. In the IX semester, for example, it was "A family house" (plans, facades, perspective). "I have to follow them - I am their leader" said L.J. Peter in "The Peter's Prescription". This quotation reflects exactly the situation we find ourselves in teaching CAAD at our department. It means that ever growing students interest in CAAD made us introduce changes in the curriculum. According to the popular saying, "The more one gets the more one wants", so did we and the students feel after the first semester of teaching CAD. From autumn 1991 CAAD classes will be carried from the third year of studying for two consecutive years. But before further planning one major steep had to be done - we decided to reverse the typical of the seventies approach to the problem when teaching programming languages preceded practical goals hence discouraging many learners.

title	The Limitations of Current Working Practices on the Development of Computer Integrating Modelling in Construction
source	computer Integrated Future, CIB W78 Seminar. Calibre, The Netherlands: Eindhoven University of Technology, september, 1991. Unnumbered. includes bibliography
summary	For the construction Industry to improve its processes through the application computer-based systems, traditional working practices must first change to support the integrated control of design and construction. Current manual methods of practice accept the limitations of man to process a wide range of building performance and production information simultaneously. However when these limitations are removed, through the applications of computer systems, the constraints of manual methods need no longer apply. The first generation of computer applications to the Construction Industry merely modelled the divided and sequential processes of manual methods i.e. drafting, specification writing, engineering and quantity calculations, estimating, billing, material ordering data-bases and activity planning. Use of these systems raises expectations that connections within the computer between the processes modelled can actually be made and faster and more integrated information processing be achieved. 'Linking' software is then developed. The end result of this approach was that users were able to produce information faster, present it in an impressive manner but, in reality, no perceived improvement in actual building performance, production economy or efficiency was realized. A current government sponsored Teaching Company Programme with a UK design and build company is addressing the problem of how real economic benefit can be realized through improvement in, amongst other things, their existing computer applications. This work is being carried out by both considering an academic conceptual model of how 'designing for production' can be achieved in computer applications and what is immediately realizable in practice by modelling the integration of a limited number of knowledge domains to which computers are already being applied. i.e. billing from design, estimating and buying. This paper describes each area of work and how they are impacting on each other

title	Integrated Design and Sustainable Building
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In the international student-project "European Environmental Campus 91 TU Delft Dordrecht" 20 students from 13 European countries worked in september 1991, during three weeks on "EcologicalSketches for the Island of Dordrecht". They worked on four different scales: the region isle of Dordt / the district Stadspolders / the neighbourhood I the house and the block. The environmentaltheme's Energy, Water, Traffic & Noise, Landscape & Soil were together with spatial analyses combined with the different scales. This combination was organised following the scheme mentioned below. The characters stand for the students. During the first period they worked in research groups, during the last period more in design groups. For instance: student L works in the beginning with the students B, G and Q in the research group water. In the last period sheworks with K, M, N and 0 in the design group Neighbourhood. Those students worked earlier in the other research-groups and contribute now in the design-group their thematic environmental knowledge. The results were presented to the Dordrecht council, officials and press. In the next project in september and october 1993 we started earlier with the design groups. Ten Dutch and ten "Erasmus" students worked for six weeks on proposals for the Vinex location Wateringenthe Hague. Each morning they worked in the research groups each afternoon in the design groups. The research groups used the EcoDesign Tools, small applications in Excel on Apple Macintoshto quantify the environmental pressure.

title	Intra-Medium and Inter-Media Constraints
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 365-380
summary	Designers work with multiple representations in a variety of media to express and explore different kinds of knowledge. The advantages of multi-media in design are well- known, and exemplified by the current interest in 'hyper-media' approaches to knowledge exploration. A principal activity in working between views in one medium (e.g. plan, section and perspective drawings), or between different representations (diagrams, maps, graphs, pictures, e.g.) is extrapolating decisions made in one view or medium over to others, so that some consistency is maintained, and implications can be explored. The former kind of consistency maintenance (intra-medium) is beginning to be well understood techniques for constraint expression., satisfaction and propagation are starting to appear in 'smart CAD' systems. The latter kind of consistency maintenance inter-media.) is different, less well understood, and will require new mechanisms for constraint management and exploration. Experiments, hypotheses, and solutions in this direction will be central to any effort that seeks to explain, emulate or assist the integrative, synthetic reasoning that characterizes environmental design and planning. This paper examines some of the characteristics and advantages of intra and inter-media constraint exploration, describes a prototype "designers workstation" and some experiments in the context of landscape planning and design, and lays out some directions for development of these ideas in future computer aided design systems.

title	A Conceptual Framework for Design and Construction Information
source	The Computer Integrated Future, CIB W78 Seminar. september, 1991. Unnumbered : ill. includes bibliography
summary	This paper tries to sketch out a conceptual framework model for design and construction information. This conceptual model is formed by extending the Finnish RATAS building product data model to include also construction activities, resources, costs, organizations, contracts, etc. and relationships between them. The overall conceptual framework model can be used to extract conceptual submodels related to the information needs of particular participants of the construction process. As an example of different views to design and construction information the views of design, cost estimating and production planning discussed in the paper. The framework model can also be used to define the position of traditional classification systems and general databases in the construction information process

title	CASOB - Simultaneous Surveying and Drawing

doi	https://doi.org/10.52842/conf.ecaade.1991.x.t7p
summary	Accurate planning and economical building within an existing structure require a complex building analysis based upon detailed scale plans. Work has shown unsatisfactory of measuring tools: (1.) Recording of measurements with meterrule and measuring tape often results in mistakes and wasted time. Since the data is not digitalized the measurements cannot be used by a CAD system. (2.) Commercially available CAD software is made only for new planning but not for planning with an existing structure. Up till now architects who predominantly work with existing structures were not able to take advantage of products in the software- and hardware market which would satisfy their needs. The problems already begin with the search for appropriate tools for the surveying of existing structures and the simplest possible transfer of the data to a CAD System. There is an increased demand for quality surveying of existing structures. In Germany, far more than 60 % of all construction planning is related to existing structures. Due to the special situation in the five new states this percentage will grow significantly. Other countries will find themselves in a similar situation. A large number of precise and analytical surveys of existing structures will be needed in a relative short time. Time pressure and stress factors at construction sites call for quality planning and economical construction which can only be accomplished with reliable and exact surveying of structures. Frustrating experiences in the field have led me to develop systems for the surveying of existing structures. With CASOB (Computer Aided Surveying of Buildings) we have a tool today that simultaneously surveys and creates a CAD compatible drawing.

title	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

summary	An approach for a graphical CAD system that is capable of representing physical and geometric aspects of a design using high-level constraints (HLCs) is presented. A prototype spatial planning system incorporating constraints is used in an interactive manner to refine designs by following an iterative approach which uses visual information to evaluate the design at each stage of iteration. High-level constraints aid this iterative approach by influencing (or constraining) the behavior of objects as they are interactively manipulated during the design stage of problem solving. High-level constraints also define the scaling properties of objects which are useful during the construction stage of problem solving. This system and its implications for the design of CAD systems incorporating HLCs are discussed.

source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 87-94
summary	This paper reviews several theoretical frameworks of visual analysis used in computer-based Visual Impact Assessment (VIA) for design decisions in architecture, urban landscape and urban planning. The discussion will focus on the underlying issues of preferences and predictions between designer and lay-public, methodologies of visual analysis, and computing media technologies due to fact that these components primarily contribute towards the result of VIA. Two different sets of visual analysis (i.e. designer’s and layman’s points of view) are presented based on Sanoff’s (1991) arguments that lay-public preferences are always become a second opinion compared to the judgments by designers. These theories will then be developed and used in the VIA experiments to understand the impact of the visuals in different media for viewers’ understanding. This paper concludes with a discussion and suggestion of analysis framework to be used for the visual experiments.

title	Constructing Three-Dimensional Mental Models from Two-Dimensional Displays
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In the present study we adopted the tasks and the experimental procedures used in a recent series of study by Cooper (1990, 1991) for the purpose of examining how we utilized two-dimensional information in a line-drawing of visual objects to construct the corresponding three-dimensional mental structure represented by the 2-D displays. We expected that the stimulus materials we used avoided some of the problems that Cooper's stimuli had, and with that we examined the effect of complexity on the process of constructing 3-D models from 2-D displays. Such a manipulation helps to elucidate the difficulties of solving problems that require spatial abilities. We also investigated whether or not providing information representing an object viewed from different standpoints would affect the construction of the object's 3-D model. Some researchers have argued that 3-D models, once constructed, should be viewer-independent or viewpoint-invariant, while others have suggested that 3-D models are affected by the viewpoint of observation. Data pertinent to this issue are presented and discussed.
