This paper adress the problem of supporting collaboration among designers in a distributed design environment. Our goal is to allow designers to work synchronously even though they are geographically dispersed. The collaboration support is based on shared object spaces as technological infrastructure and its methodology is based on Pair Programming. It was implemented using Jini/Javaspaces and it was incorporated in the Cave2 CAD framework. The implemented collaboration support is availabre as a servicee that ca be requested by the design tolls and it allows design data sharing and facilitates the experience sharing among designers. The proposed approach was validated with a case stufy on a diagram editor.

Abstract Network and Internet technology open up another domain for building future CAD/CAM environments. The environment will be global, network-centric, and spatially distributed. In this paper, we present Web-enabled feature-based modeling in a distributed design environment. The presented approach combines the current feature-based modeling technique with distributed computing and communication technology for supporting product modeling and collaborative design activities over the network. The approach is implemented in a client/server architecture, in which Web-enabled feature modeling clients, neutral feature model server, and other applications communicate with one another via a standard communication protocol. The paper discusses how the neutral feature model supports multiple views and maintains naming consistency between geometric entities of the server and clients as the user edits the part in a client. Moreover, it explains how to minimize the network delay between the server and client according to dynamic feature modeling operations.

Abstract Most consumer or commercial electronic products are electromechanical systems consisting of mechanical components such as structures, enclosures, driving systems and mechanisms, combined with electrical components such as printed circuit boards (PCBs), power supply, wires (harness) and switches. The design of such multidisciplinary products involves high coordination and cooperation between the two different engineering fields of mechanical and electrical design. However, in spite of the advancements of CAD tool development in design automation technology within each field, a gap still exists for good communication between the designers in these two fields during the course of the design. This gap makes the design process of such products time-consuming and error prone. This paper describes a research effort that facilitates multidisciplinary concurrent design for consumer electronic products. The focus is on how to integrate mechanical and electrical CAD tools into a more flexible and extensible concurrent design environment to share and communicate critical design information during the design process. A multidisciplinary concurrent design environment based on the CAD framework concept is described. Approaches for integrating the design data and information in such a multidisciplinary design environment are discussed. A prototyping system for the concurrent design of consumer electronic products is also presented.

This paper discusses the design modification issue in a collaborative assembly (co-assembly) design environment, which enables multiple geographically dispersed designers to design and assemble parts collaboratively and synchronously through the Internet. An assembly representation model, viz. feature-based hierarchical co-assembly representation, is proposed to resolve the co-assembly design issues. In order to realize the design modification, a design modification propagation control mechanism is proposed. A system framework that is suitable for realizing the design modification is also proposed and developed. Finally, the detailed design modification propagation control mechanism is demonstrated through a case study.

The architecture of an integrated suite of automation tools used to manage all project data for a major engineered facility is described. This paper discusses how these tools are configured to manage and manipulate the generation of design data by geographically dispersed team members; to support engineering, procurement, construction, operation and decommissioning; and to maintain data integrity throughout the project lifecycle. The challenges of team collaboration, knowledge management, cultural integration, and lessons learned are described.

Virtual Platform

An overview of a virtual design environment (virtual platform) developed as part of the European Commission funded VRShips-ROPAX (VRS) project is presented. The main objectives for the development of the virtual platform are described, followed by the discussion of the techniques chosen to address the objectives, and finally a description of a use-case for the platform. Whilst the focus of the VRS virtual platform was to facilitate the design of ROPAX (roll-on passengers and cargo) vessels, the components within the platform are entirely generic and may be applied to the distributed design of any type of vessel, or other complex made-to-order products.

Abstract This paper proposes an algorithm for streaming manifold solid models and NURBS geometry. A neutral streaming representation consisting of a nodes graph is encoded by a one-dimensional dynamic stack. The encoded model is transmitted over the Internet, where a two-dimensional dynamic stack decodes and reconstructs the solid model. The time and storage complexity of the algorithm are investigated. An example of streaming a solid model, resulting from a proof-of-concept implementation, is demonstrated.

Step Over

An important aspect of successful aircraft design is the concept of ‘right first time’, as any design changes downstream can be costly and may cause project delays. This is most applicable to the conceptual design phase. However, in the early stages of aircraft design, data is limited and prone to inaccuracies. Consequently, a design will typically traverse through a number of iterations, improving and refining with each step. Over the past 15 years, computer-based tools have become commonplace in aircraft design [1]. In general, most computer-based tools have been developed for the more advanced stages of the design process. For these tools to be useful in conceptual design, they must be user-friendly, interactive, and provide quick return times. A classic example is the aerodynamic load data required for structural design. Both are dependent on geometric parameters, which may still be subject to change. To complete the analysis within practical time constraints, a highly integrated and automated system is required [2, 3]. This paper presents such a system, developed using industry accepted software components including AutoCAD, VSAERO and MSC Nastran. This system allows an automatic, structured topology mesh to be generated from a basic three-view aircraft drawing, which inputs directly into VSAERO for loads calculations. The loads are subsequently transferred to MSC Patran as a pre-processor for structural analysis using MSC Nastran. If the result is unsatisfactory, the geometry or placement of structural components can easily be changed and the process repeated. The design environment was developed using FORTRAN90. The results of an application of this system to a simple wing, as well as a regional transport aircraft, are also presented.
