  Title Extraction and visualization of dimensions from a geometric model Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 4 Pages 579-589  
  Keywords Mathematical transformations;Visualization;  
  Abstract Many applications require information on dimensions of a geometric model, but these are usually not all explicitly present in the model. A method is introduced that extracts and visualizes information on dimensions from a geometric model. It first computes the medial axis of the model, and then uses this representation to determine certain dimensions in the model, in particular thicknesses and angles, and to visualize these on the boundary of the model. Presented results show that the method can visualize important dimensional information in a geometric model. © 2010 CAD Solutions, LLC.

  Title Experience in development of translators for AP203 edition 2 construction history Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 4 Pages 565-578  
  Keywords Standards;  
  Abstract Over the last two decades, the mechanical CAD industry has witnessed the development of many powerful 3D CAD software products built upon proprietary geometric kernals. The ISO 10303 STEP standard was developed, with the Application Protocol (AP 203) in particular, to provide a medium for product data exchange of lower-level geometry of mechanical parts and assemblies. A recent version, AP203 Edition 2, introduced the exchange of product data using a hybrid model containing construction history, GD&T, parameters and other high-level content. This paper presents an interpretation of the schema definitions provided under the current standard, presents a generic approach to map feature history data between CAD systems, discusses an implementation of this approach for data translation, and discusses the issues in the standard realized during this effort. © 2010 CAD Solutions, LLC.

  Title Assessment of 3D annotation tools as a substitute for 2D traditional engineering drawings in aerospace product development Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 4 Pages 547-563  
  Keywords Computer aided design;Concentration (process);Engineering;Product development;Software design;Three dimensional;  
  Abstract Reducing the costs of bringing a new product to market is an objective common to all industries. In aeronautics, one of the options being pursued to achieve this goal is to eliminate the use of traditional engineering drawings from the product development process-chiefly by integrating a portion of the information normally contained in these drawings into a 3D digital mockup (DMU). Before making this major change, several industrial practices must be revised and certain technological problems need to be resolved. One of the challenges is the transposition of the information found on traditional 2D engineering drawing, namely notes, dimensions and tolerances, to a 3D DMU. This article presents an evaluation of the feasibility of enriching 3D DMU with the aim of eliminating engineering drawings, based on the results of experiments in transposing samples of aerospace 2D engineering drawings to 3D environments using Catia V5 R17 SP6, a Computer-Aided Design software product. Experimental results show that placing annotations on the 3D DMU is feasible even for complex aerospace drawings. These results should help engineering design organizations decide if eliminating traditional engineering drawings is suitable for them. © 2010 CAD Solutions, LLC.

  Title Kinetic art design system comprising rigid body simulation Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 4 Pages 533-546  
  Keywords Computer aided engineering;Three dimensional;  
  Abstract Kinetic art, such as mobile sculptures and balance toys, is art that involves movement. The design of original kinetic art is difficult because one must consider physics in order to predict the result. Current computer aided design (CAD) and computer aided engineering (CAE) tools are of limited use when designing such dynamic objects because typically these systems are entirely separated. In this paper, we propose a new system for designing original kinetic art objects in which a three-dimensional (3D) geometrical modeling interface and a rigid body simulation are combined. In this study, we introduce an implementation technique to achieve real-time responses and present a prototype system. To demonstrate the techniques effectiveness, we report the results of user studies and show several objects designed on the system. © 2010 CAD Solutions, LLC.

  Title Raw shaping form finding: Tacit tangible CAD Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 4 Pages 505-531  
  Keywords Experiments;  
  Abstract This paper is aiming at the identification of essential voids in the support of design processes offered by commonly available methods and tools. Some remarkable results were obtained during design sessions with novices and experts by engaging them in tangible experiments that were designed to trigger and enhance their skills, tacit knowing and creativity that enable them to represent their ideas and concepts in an intuitive way. We explored the differences in designers behavior during use of “analogue” and digital representation tools. We will explain our laboratory experiments, test results, educational embedding and creative opportunities that emerge from hybrid design tools. Furthermore we propose an exciting hybrid design tool to bring back the tacit and tangible elements of design processing into CAD systems. © 2010 CAD Solutions, LLC.
