Strategies for the Transition to CAD Based 3D Design Education

AbstractIn the proposed paper, our experience in managing the transition from traditional design education to CAD based design as a case study for comparison is documented. Use of CAD technologies on both undergraduate and Master level is also discussed.

Applying 3D Scanning and Modeling in Transport Design Education

Advanced 3D Laser Scanning processes have developed over the last decade and are now available and affordable for medium to large companies as well as education. This study examines the overall efficiency of the 3D scanning process and potential value for use in design education. The potential effectiveness of the 3D laser technology for education is also assessed with live projects. This article explores a reverse engineering approach for product form design. Three-dimensional models of design concepts are created in clay, and data points on the surface of the model are then measured using a non-contact 3D scan device. The resulting data is then imported into an appropriate CAD design package for further design development.

A comparative study of 3D scanning in engineering, product and transport design and fashion design education

The aim of this paper is to evaluate the use of three‐dimensional (3D) scanning technologies for design and engineering courses. This paper will provide a comparative discussion of the current 3D scanning technologies; and then describes three experimental studies in engineering, transport design and fashion design. Using 3D scanner technology the experiments tested the transferral of a variety of different data from scanned organic 3D shapes to 3D CAD packages for learning and teaching in undergraduate education.

Virtual stonehenge reconstruction

Visual and spatial technologies are increasingly revolutionising how archaeology and many other disciplines understand the past in relation to the contemporary world. From digital objects to landscapes, through geophysics, geographical imaging systems and the creation of virtual worlds, new technology provides alternative routes to seeing and understanding both past and present [1]. This research paper describes an interdisciplinary art and design approach to rebuilding and visualising phase 3vi of the Stonehenge site for interactive cultural heritage applications in the 21st Century. A 3D digital research team based at the School of Art, Design & Architecture collaborated with music technologists, sculptors and game designers to gather, interpret, re-imagine and digitally re-model historical and contemporary data on Stonehenge to create a virtual 3D reconstruction of Stonehenge phase 3vi. The researchers discuss the range of digital data, tools, methods used in this phase of the Virtual Stonehenge reconstruction project.

Innovative potential of 3D software applications in fashion and textile design

Advanced cloth simulation plug-in tools are increasingly being used by designers in movies, television, advertising and computer games, to take the strain out of creating and simulating realistic cloth effects for dressing virtual characters. This paper describes experiments into designing textiles and clothing using 3D graphics software and a digital cloth dynamics plug-in, which are an integral part of PhD research in progress. The methods used in testing the 3D software and the cloth dynamics plug-in illustrate the experiences of a designer/learner. The results identify designer/learner needs and expectations for the further educational development of the research and use of cloth simulation tools in textiles/fashion design in the near future.

Experimental Investigation of Sheet Metal Forming Using a Recyclable Low Melting Point Alloy Tool

Abstract Due to intense competition in automotive industry, new car models have to be launched as quickly as possible. A re-evaluation of the design and development phases has reshaped product development in order to get product earlier than competitors. Prototype production is one of the longest stages of product development due to physical verification activities. Shortening of this process will provide more opportunity to get project schedule earlier. Rapid prototype technologies are usually used as a guide for visual and packaging analysis. However, there is a requirement to use these parts for functional testing as well. Developing alternative rapid tooling methods which shorten the physical prototype production phase, while adequately supporting visual, packaging and functional aspects of sheet metal forming, can lead to considerable savings in vehicle prototype development. In this study, sheet metal prototype part using recyclable low melting point alloy was experimentally investigated by analysing dimensional conformance of tools and parts. In addition to wear performance, thickness reduction was investigated for stamped parts.

Digital sculpting for historical representation: Neville tomb case study

ABSTRACT Despite digital 3-D polygon modelling applications providing a common and powerful tool-set for archaeological, architectural and historical visualisation over recent years, the relatively recent developments in high-resolution sculpting software allow for the possibility to create digital outcomes with a degree of surface fidelity not previously obtainable from the more widely used poly-modelling software packages. Such digital sculpting applications are more commonly applied within the video games and TV/motion picture industries, the intention of this paper is to show how such tools and methodologies together with existing scanned data and some historical knowledge can remediate and re-imagine lost sculptural form. The intended research will focus on an examination and partial re-construction of the tomb of Sir John Neville, 3rd Baron Raby located at Durham Cathedral, County Durham UK.

Application of carbon reinforced composites and rapid prototyping in low volume automotive production

Abstract In this publication, a method was developed for the production of plastic parts for the use in low volume automotive production. The hollow parts having a complex geometry were produced in blown plastic injection molds. The part production method employed a combination of carbon fiber reinforced composites and rapid prototyping technology. Surface operations were applied on the core model and the effects of the surface quality were researched as a case study. The fused deposition modeling method was used to build the core from soluble material. This technique affected the inside surface roughness and quality of the final parts. As these types of components require smooth surfaces for good air flow and low resistance, the surface area of the physical model of the soluble core was unfortunately too rough to be used directly in the carbon fabric application process and consequently, required preliminary surface treatment in order to improve the surface quality of the manifold part. Specimens were fabricated using different surface treatments in order to determine the smoothest surface quality. The best result was obtained using the acetone-gelcoat post-processing method.
