summary	It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.

title	XML for Flexibility an Extensibility of Design Information Models
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title	Distributed Representation of an Architectural Model
source	Harvard University
summary	This thesis proposes a new strategy for design representation that uses dynamically decentralized design objects, distributed over the web and instantiated just-in-time, instead of the traditional centralized, static and local CAD model. It addresses the problem of coping with dynamic information changes that architects face when designing with increasingly time-sensitive product information from multiple suppliers. The dissertation describes the new distributed architecture for design representation, and outlines a corresponding new process model to address the needs of AEC (Architectural, Engineering and Construction) industries' architectural designers during design and procurement phases. The feasibility of the process was tested in a prototype system that combines existing state-of-the-art technologies. The prototype integrates the direct manipulation functionality of Autodesk's i-Drop technology with the Internet communication protocols HTTP and TCP/IP, and a VBA macro running from within AutoCAD 2000i. In the proposed model, libraries of AEC objects, representing suppliers' products, are located in multiple suppliers' databases and are made available to CAD designers remotely over the Web. Suppliers using the system are expected to produce product information as XML documents. This standardizes the interface with the remote designers.

title	Case-based Reasoning in Collaborative Design: The role of product models and information structures
doi	https://doi.org/10.52842/conf.ecaade.2001.092
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 92-97
summary	This paper discusses methods for information management through the rational application of IT within collaborative design. We explore the possible integration of the platforms of case-based reasoning and information structures. We examine the potential combination of existing techniques (CAD-tools, word processors, general applications, WWW) and standards (IFC, national classification systems) into a system for information management. We focus on the designers’ use of heterogeneous information and the further development of a prototype based on product-model and process-model technology. Today, XML helps us structure various kinds of information before the system performs case-based reasoning sessions. The aim is to promote efficient and flexible information management in a casebased design process. Through the use of standardized product models, this information will be sharable and suitable for reuse and feedback. The more often the information is reused, the more general and adaptable it becomes i.e. it evolves. This scenario requires, though, efficient information management in the design office: a quality system for evaluating the information for reuse, consequent use of standardized product models and IT.

title	Representation of architectural analyses. Two prototype applications
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 495-505
summary	We present a methodology for decomposing documents by content and integrating these into a rich information structure. This implies both expanding the document structure, replacing document entities by detailed substructures, and augmenting the structure’s relatedness with content information. This paper focuses on some of the representational issues involved in the process of interpreting, breaking up, and relating documents. We describe a prototype application as a tool for building up, storing, and presenting architectural analyses in an educational setting implemented using XML, discuss a similar prototype application to be implemented using sorts, and compare these two different methodologies.

summary	A collaborative design project consists of a team of design partners who are engaged during the period of the project in a particular design task. The group forms a short-lived community with the goal to create a design. The environment in which this is done today, consists of the participants office spaces, completed with equipment such as drawing tables, coffee machines, fax machines, CAD stations, etc. None of these elements reflect the existence of the (temporary) community that a design partner participates in. In this workshop paper we propose that the current two-dimensional desktop metaphor in a computer does not adequately support collaborative design. The typical 2D-desktop multiple open windows with different applications gives a fractured view of the design project in which by contrast the designer as a person conceives of himself as a whole. Moreover, the sense of place, or a consistent identity in which the design takes place is also lacking. The notion of _virtual environmentsÑ can assist in further developing design support for collaborative design in the future, as is sketched in the following outline.

summary	The present use of digital media in architectural practice and education is primarily focused on representation, communication of ideas and production. Designers, however, still use pencil and paper to assist the early conception of ideas. Recently, research into providing digital tools for designers to use in conceptual designing has focused on enhancing or assisting the designer. Rarely has the computer been regarded as a potential teaching tool for design skills. Based on previous work by the author about visual thinking and the justification for a digital design assistant, the intention of this paper is to illustrate to the reader the feasibility of a digital design coach. Reference is made to recent advances in research about design computability. In particular, research by Mark Gross and Ellen Do with respect to their Electronic Cocktail Napkin project is used as a basis on which to determine what such a digital coach may look and feel like.

source	Automation in Construction 10 (4) (2001) pp. 527-540
summary	Further developments in an ongoing multi-disciplinary research programme concerning the automation of sewer surveys are reported. Previous papers have suggested a theoretical model for use in establishing a frame of reference for closed circuit television (CCTV) camera images of non-man-entry (NME) brick sewers, in order to enable quantitative observations to be automatically acquired employing computer vision techniques. Herein is discussed a simulation testing strategy designed to determine the model's predictive accuracy and thereby assess the corresponding assumptions made. Test results are presented which display robust model characteristics. Further developments are then considered in the context of in-service practice.

summary	The way screens are attached to architecture at present limits architectural surfaces to carriers of signs. The research presented in this paper offers a possible solution that allows architectural surfaces to be both a space-defining element that has certain architectural material qualities and at the same time allows media technology to be embedded. These surfaces can alter their state from static material to dynamic image in an instance. The paper presents a prototype capable of fulfilling this requirement. It also positions the research within the architectural discussion by comparing it to works of others and confirming its research value by reference to work in a similar direction. Finally, the paper evaluates the research and concludes that it could offer a ‘fabric’ to be used as a sort of media clothing for architecture in the electronic age (Ito, 2001).

Introduction of this methodology intends to improve the natural landscape cooperation in China urban planning through visual protection. Combining with popular CAD software such as AutoCAD and Microstation, the research team uses ArcView GIS software and its 3D Analyst extension to accomplish a set of research procedure, which includes data modification, model making, viewshed and view sensibility analysis. In addition, this system can create simultaneous 3D scenes or hire other information media as reference tools for professional analysis, design consultation and intercommunication. The core technologies of this proposed system are viewshed calculation and overlay analysis. In viewshed analysis, human visual characteristics are simulated by a series of ergonomics parameters of viewpoints. Viewshed of each viewpoint can be calculated into vector data and mapped by polygons identifying which region is visible and which is not. Overlay function of the proposed system is used in visual sensibility analysis to achieve the division of higher visual sensible area which indicates the common visible area from different viewpoints. Additionally, viewshed maps and visual sensibility results can add more information to mark out the areas that can satisfy certain visual parameters such as appropriate visual angle or visual distance. These overlaying results can visualized the visible areas into hierarchical visual perception quality categories in order to define the visual landscape significance of particular planning regions. A case study was operated to evaluate this system. The case is in Zhongshan city, Guangdong Province of China. Jinzishan hill region is the study site that picked by collaborating discussion of research team and the local government. It is located on the edge of urban built-up area. Jinzishan massif is the prominent landscape element of the surrounding environment. There are three topics in Jinzishan visual perception in this paper. The first topic is the visual quality evaluation of the intersections of its surrounding road system. The second is the integrated visual perception of two main roads called Qiwandao and Bo‚Äôailu. Finally is the analysis of the hill skyline visual quality in surrounding area. The analysis results in GIS vector data can be converted into popular data format and combined with other spatial information for practical application. And comments for future urban planning are collected and analyzed by professional responses to the computer-generated information investigation.

summary	The ideation phase in the design process includes ambiguous, quick, and exploratory representations: sketches and models. A sketch in perspective visualizes a single view, lacks dimensions, and is not to scale. Models at full scale are not always viable and printing them in 3D requires CAD models whose level of definition is premature in ideation. Virtual Reality (VR) and mixed reality allow for immersive and full-scale 3D sketching. 3D printing these “virtual drawings” turns models and sketches into a single representation existing simultaneously virtually and physically. This article reports two exploratory exercises in industrial design in which three types of 3D sketches were used: virtual on tablets, mid-air with controllers and a VR headset, and 3D printed. Reflections by researchers and participants about these exercises were used to begin elucidating the impact of this new media for ideation in the design process.
