title Is it Possible to Design in Full Scale? A CAD Tool in a Synthetic Environment
doi https://doi.org/10.52842/conf.caadria.1999.043

summary This project developed a Virtual Architectural Design Tool (VADeT) executed in the C2 Virtual Reality (VR) space. C2 is a synthetic CAVE environment providing a full-scale setting for image projection and perception. Applying this tool for design offers four advantages over other CAD systems. First, it enables navigation performing in full scale to create the sense of immersion and reflection of the seeing-as. Second, it allows the creation, modification, and editing of three-dimensional objects in a virtual space. Third, designs can be modified and viewed simultaneously inside or outside of the generated model to obtain the best design products. Fourth, the entire design process can be recorded and played back. Collectively, this tool serves the purposes of: (1) a three-dimensional sketching tool for manipulating 3-D objects, (2) a design study tool for transparently displaying the design processes, and (3) a design teaching tool to demonstrate the processes by which designers do design. Thus, design in a full-scale representation not only is possible but also is a new and unconventional mode that will heavily influence design thinking.

title Public Participation in Urban Design Based on Information Technology
doi https://doi.org/10.52842/conf.caadria.1999.393
source CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 393-402
summary For years, lack of public participation has affected the quality of design and planning. The developing cities constantly face the anti-development sentiments on the part of local residents because of controversial decision of development. Rapid development of information technology provides us with a chance to mend the delay of communication with the public in design procedure. It makes it possible to get the resident's reaction to a new project. Unlike a purely CAD-based environment, computer application to urban design is based on a blend of computer-aided design, spatial information system, and interactive multimedia. It is the combination of geometric, geographic, and annotated information and the need of data integration by collaboration and meanwhile it provides opportunities of participation. Due to the position at the crossover of architecture, landscape architecture, and planning, urban design attempts to control the proceeding in both design improvisations and socio-economic policies. In this proceeding, public participation plays an important role in exchanging opinions with the masses. In the situation of participation in China, we can synthesize some useful methods of public participation in the urban design by means of computer simulation, computer communication, and diverse software and tools, etc.

source CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 81-87
summary This paper presents a case study of the application of computer techniques for design communication and visual impact analysis. We were sponsored by China Light & Power Company Ltd. To simulate the design of a proposed electricity substation and its it is setting in a residential neighborhood. During a five-week intensive study, we took nearly one thousand photographs of the existing site. We also created a three-dimensional CAD model of the proposed substation, and produced perspectives from points of view analogous to the photographs. We applied Apple Quicktime VR technology to document the site environment with 360-degree panoramas. We then montaged the computer-generated panoramas with those taken from the real environment. A navigable virtual environment, architectural animation and set of still images were presented to the public in September 1998. The reactions from the regional council members and local residents nearby were recorded to provide evidence to measure the effectiveness of digital architectural design communication.

title CAD Interfaces to the ARROW Manufactured Product Server
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

title Evolutionary Design Tools for Mass-Customisation
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 152-156
summary This paper describes an instance of the author’s ongoing research in the field of Generative Design. The work is based on the premise that computer-aided design (CAD) should evolve beyond its current limitation of one-way interaction, and become a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customised designs which exhibit common features. The understanding of fundamental shape-forming processes in nature inspires us to move beyond the existing CAD paradigms and re-examine the way we can benefit from the computers in design. We can use this knowledge to create a new generation of computer-based design tools which use evolutionary search algorithms to generate create a common family of individual designs optimised according to particular criteria, while supporting our design intuition. The author explores this idea by illustrating a research project between the Hong Kong Polytechnic University and Deakin University (Australia). The project implements a multi-user oriented design tool for evolutionary design, which was tailored to produce a simple object such as door handle. The paper first gives a short historical and philosophical to the work, then describes the technical and algorithmic requirements, and implementation of the system. It concludes by describing an experiment in which the system was used on a "live" test group of people to generate individual, mass-customised designs.

title Towards a Multi-Agent System for Network Decision Analysis

summary We introduce the outline of a multi-agent system that can be used for network decision analysis. This system is based on cellular automata and multi-agent technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior, in architecture and urban planning.

title Arties: Meta-Design as Evolving Colonies of Artistic Agents
source International Conference on Generative Art
summary Meta-design, the act of designing a system or species of design instead of a design instance, is an important concept in modern design practice and in the generative design paradigm. For meta-design to be a useful tool, the designer must have more formal support for both design species definition/expression and the abstract attributes which the designer is attempting to embody within a design. Arties is an exploration of one possible avenue for supporting meta-design. Arties is an artistic system emphasizing the co-evolution of colonies of Artificial Life design or artistic agents (called arties) and the environment they inhabit. Generative design systems have concentrated on biological genetics metaphors where a population of design instances are evolved directly from a set of ‘parent’ designs in a succession of generations. In Arties, the a-life agent which is evolved, produces the design instance as a byproduct of interacting with its environment. Arties utilize an attraction potential curve as their primary dynamic. They sense the relative attraction of entities in their environment, using multiple sensory channels. Arties then associate an attractiveness score to each entity. This attractiveness score is combined with a 'taste' function built into the artie that is sensitized to that observation channel, entity, and distance by a transfer function. Arties use this attraction to guide decisions and behaviors. A community of arties, with independent evolving attraction criteria can pass collective judgement on each point in an art space. As the Artie moves within this space it modifies the environment in reaction to what it senses. Arties support for Meta-design is in (A) the process of evolving arties, breeding their attraction potential curve parameters using a genetic algorithm and (B) their use of sensory channels to support abstract attributes geometries. Adjustment of these parameters tunes the attraction of the artie along various sensing channels. The multi-agent co-evolution of Arties is one approach to creating a system for supporting meta-design. Arties is part of an on-going exploration of how to support meta-design in computer augmented design systems. Our future work with Arties-like systems will be concerned with applications in areas such as modeling adaptive directives in Architecture, Object Structure Design, spatio-temporal behaviors design (for games and simulations), virtual ambient spaces, and representation and computation of abstract design attributes.

title Digital Environments for Learning and Collaboration Architecture, Communication, Creativity, Media and Design Process
doi https://doi.org/10.52842/conf.acadia.1999.040
source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 40-52
summary Digital networks are gaining importance as environments for learning and creative collaboration. Technical achievements, software enhancements, and a growing number of applicable principles make it possible to compile complex environments that satisfy many aspects necessary for creative collaboration. This paper focuses on three issues: the architecture of collaborative environments, communication in these environments and the processes inherent to creative collaboration. The information architecture of digital environments looks different from physical architecture, mainly because the material that it is made out of is information and not stone, wood or metal and the goal is to pro-vide appropriate paths and views to information. Nonetheless, many analogies can be drawn between information architecture and physical architecture, including the need for useability, aesthetics, and consistency. To communicate is important for creative collaboration. Digital networks request and enable new strategies for communicating. Regarding the collaborative creative process we have been able to detect principles and features that enhance this process, but there are still many unanswered questions. For example, the environment can enable and improve the frequency of surprise and coincidence, two factors that often play decisive roles in the creative processes but cannot be planned for in advance. Freedom and transparency within the environment are other important factors that foster creative collaboration. The following findings are based on numerous courses, which we have taught using networked environments and some associated, research projects that helped to verify their applicability for architectural practice.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title PUSH: Generating Structural Form with Haptic Feedback
doi https://doi.org/10.52842/conf.acadia.1999.252
source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 252-259
summary This paper looks into the use of haptic feedback (also known as force feedback) in helping generate and evolve structural forms, a process that is important to students of architecture and engineering. Force feedback provides these students with opportunities to “feel and manipulate” virtual 3D structures in a very natural and intuitive way. It also makes it possible to have real time holistic evaluation of structures in a qualitative rather than quantitative manner, something of particular importance to introductory-level students. Furthermore, the incorporation of force feedback into a highly interactive multimodal structural behavior application furnishes students not only with a means to observe virtual structures but also a tool to help generate and develop efficient, innovative and alternative ones. This also is of vital importance to students of architecture as they are often challenged to explore non-conventional forms.

Implementing force feedback systems for these purposes need not necessarily require sophisticated and expensive VR hardware. This paper describes a structural behavior application called PUSH which utilizes a simple force feedback joystick connected a reasonably fast desktop computer.

title Geographic Information Database for Landscape Evaluation

summary In a landscape evaluation of a large-scale facilities construction such as garbage disposal facilities, it is necessary to grasp landscape characteristics of the area that is able to observe object facilities. This landscape characteristic consists of both a geographical characteristic (landscape resources, public space, districts designated by various urban planing laws, etc.) and a visual characteristic (visibility / invisibility range, distance from the object). The facilities design with consideration for landscape requires a geographic information database for the landscape characteristic, which enable planners to share the geographic information in the area. Authors proposed Network-based Dynamic Evaluation Process for urban landscapes in CAADRIA98, and illustrated the need of the common place that shares geographic information in the process. The system has function to provide the information of the area with layered maps simply. However the system developed with HTML Layer Function, that has limited to update data and boolean operate of layers. For using the system for practical purposes, it should conduct a GIS lookup and report back, via HTML. On the other hand, at present, there are various analogue thematic maps, digital maps are not prepared enough for landscape evaluation. It causes that landscape design process is not efficient. Also, a potential (importance) of viewpoints for evaluating facilities design have been defined by qualitative analysis so far, therefore a quantitative comparison of viewpoints was not available. As a solution of those problems, authors are tackling the development of Geographic Information Database (GIDB) by using GIS. In this paper authors give an outline of GIDB composed of overlaying various digital thematic maps included visual characteristic of the facilities. As a case study, in construction of the garbage disposal facilities in Kumamoto city, the important viewpoints was extracted by GIDB.

summary In the past CAFM system study, we proposed a system for supporting data-processing and plan-drafting, on the assumption that it is to be used in different stages of Building Construction, Interior Spatial Planning and Maintenance. By the above system, we have developed a CAFM system using the DBMS (Data Base Management System), CAD (Computer Aided Design) and Spread Sheet as the analysis tools. Management system with FM-related data editing functions such as 'Input', 'Modification', 'Deleting', etc, are proposed. To promote the FM business smoothly, information should be shared among departments concerned, and informative administrative framework should be organized. This time, we propose a prototype of CAFM system on INTRANET which is developed for general users that permits browsing and downloading of system database.

summary Design studio still plays a very important role in architectural design education today since teachers and students can exchange their thinking directly. In the whole teaching/learning process, there are a lot of information to be exchanged between the teachers and the students. How to organize the information and record the whole teaching/learning process is very interesting to us. The increasing use of CAD raises some problems with its advantages when the amount of compute-files becomes very big and they are in different formats. In the third year design studio teaching in the academic year 1998/99 at Department of Architecture in Southeast University, we try to use WWW techniques and features to organise the design information. We try to integrate the teaching programme, the project information, the reference material and the students' work together, to record and monitor the teaching process. Since the teaching programme is clearly organised, we could use some strategies and ideas to control the organisation of file storage and presentation. It creates the basis for the further development of applying network to aid the studio teaching.

summary In this paper, we discuss about the architectural design collaboration and information management based on the worldwide network. Internet and WWW are rapidly infiltrating through the architectural schools in the world, so it is easy to communicate and share the design information with web homepage and e-mail. But, a set of homepage and e-mail is not sufficient for easy and smooth design. Because of the data management method and system for network collaboration is not yet well organized nor well developed. In this paper, we report the results of two Virtual Design Studio projects that we have experienced and intend to analyze the problems to exchange and share the design information on the web. Then we propose the collaborative design system environment and evaluate it from the result of the experimental third Virtual Design Studio project that we have executed.

summary In the age of information technology, architectural design problems become increasingly complex, the finding of optimal solutions has become more difficult and obscure. Computer-aided design techniques have been applied to solve these ill-structured design problems; however, most of these applications have been used for graphical automation. Design improvement in quality has not been achieved using traditional computer programs. To handle the critical design decision problems, design systems need to be structured based on theoretical problem solving models. This would enable the design system to handle the problem solving design knowledge as well as the various technological aspects and geometrical representations. A theoretical model, knowledge-aided design, is proposed. Knowledge-aided design is a conceptual and theoretical model based on fundamental principles of design. It provides a problem-solving environment and a procedure for knowledge-based computer-aided architectural design based on cognitive science and artificial intelligence techniques. As a partial implementation of the theoretical model, the development of knowledge-aided design system for intelligent building design is described.

title Generative Polymodal Music Process
source International Conference on Generative Art
summary We present underlying ideas used to develop an Algorithmic Composition software named KYKLOS. It was designed to generate music based on generalised musical scales and modes. It is an interactive sonic device to be applied in composition as well in performance. The sonic output of the whole process can be described as generalised polymodal music since “synthetic scales” are generated by the algorithm. This environment can be used in a Computer Assisted Composition manner in order to generate MIDI files. On the other hand, it can equally be used as a performance environment in which a dynamic change of parameters enables a real time control of the sonic process. Recently, we advocated that several mathematical applications in Computer Music can be understood as Sound Functors [1]. In extension, we describe here a sound functor used to model scales and modes. As can be verified, part of early investigations on mathematical structures in music studied musical scales and modes using Combinatorics, Fibonacci Series and Golden Mean in order to understand compositional processes which use modal concepts. Using the Functor definition it is possible to enumerate n-scales as a sequence of integers. Each value in that sequence gives the distance (in half tones) between two consecutive tones. For example, the sequence 3:2:2:3 is interpreted as a pentatonic scale C-Eb-F-G-Bb, and as defined above it is a C mode. So, if we apply cyclical permutations, (n-1)-sequences of numbers should be interpreted as n-modes of tones. Our algorithmic implementation is described briefly. A n-mode is defined as an array with n-1 integers [a1, a2, ...an-1]. Each array generated at k-th step can be read as a number a1a2a3 ....an-1 in decimal representation, where ai is a integer between 1 and 9. We denote the number obtained at k-th step as (a1a2a3 ...an-1)(k) . The rules to implement the algorithm are the following:1) V0 = (1, 1, 1, 1 ......,1) (initial n-mode)2) ? ai ? 11 with i= 1, 2...n-1 (octave range constraint)3) Vk = (a1a2a3 ...an-1)(k) < (b1b2b3 ...bn-1)(k+1) = Vk+1 where aj ?bj , 1? j ? n-1.4) Vmax = (13 – n, 1, 1, ...,1)In this paper we start with a theoretical view and an introduction on the algorithmic mechanism used. Further, we present a concept of man ? machine interaction used to create the composition environment. We also describe the compositional graphic interface developed and general functions of the system. Finally there is a set of music examples generated by KYKLOS as MIDI files.

summary EFA ‘ 99 covered the use of light throughout 1:1 simulation. As a rule the field of light design has a closer relation with simulation in true scale. Therefore, it is surprising that a conference dealing with this field did not take place at an earlier stage which might be due to the differing approaches concerning implementation and working focus at the various laboratories. The remarkable achievements of the individual lighting companies on the market regarding research work seem very promising and necessarily are to be duly acknowledged also on the part of academic circles. Furthermore, a productive exchange of information might develop between the, somewhat incompatibly seeming, interest groups. More interaction would surely prove wise, as the stage for successful research work in the field of light design and light impact is only to be set by combining all strengths.

title 1:1 SIMULATION IN ARCHITECTURAL PRACTICE
source Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 57-66
summary Full-scale mock ups have a long and successful history within the architectural profession. There is consensus that future users as well as professionals are better able to make design decisions in full-scale and in real time. Full-scale analogue simulation must be implemented as part of a typical design process for the sake of our clients as well as the sake of the profession: the cost of doing anything less is enormous. Altonview believes it is possible to develop an economical, flexible and utilitarian architectural environmental system (AES) which can be used, with modifications, by all professionals. Additionally, the media needs to take an interest in the AES movement, which will change their focus from the building image to the user. American architectural schools need to increase their interest in AES as well. The AES movement can be closely linked with the zeitgeist that will define the next century as seen in further examples and references from the popular press.

title Simulation-driven Design
source KTH Stockholm
summary Efficiency and innovative problem solving are contradictory requirements for product development (PD), and both requirements must be satisfied in companies that strive to remain or to become competitive. Efficiency is strongly related to ”doing things right”, whereas innovative problem solving and creativity is focused on ”doing the right things”. Engineering design, which is a sub-process within PD, can be viewed as problem solving or a decision-making process. New technologies in computer science and new software tools open the way to new approaches for the solution of mechanical problems. Product data management (PDM) technology and tools can enable concurrent engineering (CE) by managing the formal product data, the relations between the individual data objects, and their relation to the PD process. Many engineering activities deal with the relation between behavior and shape. Modern CAD systems are highly productive tools for concept embodiment and detailing. The finite element (FE) method is a general tool used to study the physical behavior of objects with arbitrary shapes. Since a modern CAD technology enables design modification and change, it can support the innovative dimension of engineering as well as the verification of physical properties and behavior. Concepts and detailed solutions have traditionally been evaluated and verified with physical testing. Numerical modeling and simulation is in many cases a far more time efficient method than testing to verify the properties of an artifact. Numerical modeling can also support the innovative dimension of problem solving by enabling parameter studies and observations of real and synthetic behavior. Simulation-driven design is defined as a design process where decisions related to the behavior and performance of the artifact are significantly supported by computer-based product modeling and simulation. A framework for product modeling, that is based on a modern CAD system with fully integrated FE modeling and simulation functionality provides the engineer with tools capable of supporting a number of engineering steps in all life-cycle phases of a product. Such a conceptual framework, that is based on a moderately coupled approach to integrate commercial PDM, CAD, and FE software, is presented. An object model and a supporting modular modeling methodology are also presented. Two industrial cases are used to illustrate the possibilities and some of the opportunities given by simulation-driven design with the presented methodology and framework.
