A Case Study on CAD/CAM Data Transfer in CIM Environment
3 A Case Study on CAD/CAM data transfer in CIM Environment K. P. Mahadevan J.Mou M R. Henderson D. L. Shunk Department ofI&MSE Arizona State University Tempe, AZ 85287 US.A. Abstract This case study enumerates the steps involved in testing the data exchange among dissimilar CAD systems using a standard exchange mechanism and discusses the level of inter-operability that can be achieved to facilitate successful transfer of CAD data among three CAD software's namely ProlE version 17, I-DEAS Master series version 3.1 and AutoCAD release 13 in a CIM environment. First the Initial Graphics Exchange Specification (IGES) is used as the data exchange mechanism to test these software's using a standard test procedure. The same test procedure is then used to find out the effectiveness of the data exchange between ProlE and I DEAS using a different exchange standard called the Standard For Exchange Of Product Model Data (STEP). AutoCAD does not support STEP. Experimental results show that ProlE and I-DEAS have the capability to share complete CAD information but AutoCAD has some limitations in transferring information on surfaces and solids using IGES. By using the STEP translator, we are able to translate CAD data efficiently one way from ProlE to I-DEAS and vice versa but have some difficulty carrying out back and forth data transfer between tl1em.

Integrated Feature-Based and Geometric CAD Data Exchange
ACM Symposium on Solid Modeling and Applications (2004) G. Elber, N. Patrikalakis, P. Brunet (Editors) Integrated Feature-Based and Geometric CAD Data Exchange Steven Spitzy and Ari Rappoportz Abstract Data exchange between CAD systems is an extremely important solid modeling concept, fundamental for both the theory of the field and its practical applications. The two main data exchange (DE) paradigms are geometric and parametric DE. Geometric DE is the ordinary method, in which the boundary representation of the object is exchanged. Parametric (or feature-based) DE is a novel method where, given a parametric history (feature) graph in a source system, the goal is to construct a graph in the target system that results in similar geometry while preserving as much parametric information as possible. Each method has its uses and associated problems. In this paper, we introduce Geometry Per Feature (GPF), a method for integration of parametric and geometric data exchange at the single part (object) level. Features can be exchanged either parametrically or geometrically, according to user guidelines and system constraints. At the target system, the resulting model is represented using a history tree, regardless of the amount of original parametric features that have been rewritten as geometric ones. Using this method we maximize the exchange of overall parametric data and overcome one of the main stumbling blocks for feature-based data exchange.

CAD/CAM and the Exchange of Product Data
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by CERN Document Server CAD/CAM and the Exchange of Product Data N.-J. Høimyr CERN, Geneva, Switzerland Abstract A 3D model defined in a CAD-system is used as a basis for design and product development. The concept of Computer Integrated Manufacturing (CIM) consists of sharing information between different applications used for design and manufacturing of a product so that the requirements of the manufacturing processes are taken into account already at the design stage, allowing shortened product development cycles. Later on in the product’s life-cycle, the same product data could be used to support e.g. maintenance processes. This process requires that different CAx applications can share the same product model. Thus CIM puts stringent demands on the abilities of CAx tools to exchange product data and the methodology used in the design process. The emerging ISO STandard for the Exchange of Product Data (ISO 10303 STEP) addresses some of these needs, while use of existing de-facto standards require a pragmatic approach and careful selection of CAD-tools and planning of design methodology. Keywords: CAD/CAM, Shape Geometry, Product Data, STEP, Engineering, Manufacturing 1 Introduction, CAD-data exchange is often the bottleneck A Computer Aided Design (CAD)-system used to be a computerized drawing automation tool. Nowadays CAD/CAM systems are 3D solid modelling tool which allow for complete definitions of product geometry in an electronic form. This data can be used as a basis for numerous other applications. -

CAD among joint venture partners. Because of the lack of any tools also opened new opportunities, such as enabling common set of tools, a common format for neutral file manufacturing instructions to be derived automatically exchange is needed. Using a neutral standard for and executed directly from the drawing. Nevertheless, as transferring information across systems drastically computer design and manufacturing tools proliferated to reduces the requirements for translators. The cost meet increasingly complex and diverse engineering benefits are suggested by the reduction in necessary needs, so did the formats that each tool used to capture translators shown in Fig. 1. It illustrates that by using a and store product data. While paper drawings can be neutral file exchange, the number of translators marked up by anyone with a pencil, a product model (for N systems) can be reduced from scaling as n (n–1) that cannot be interpreted by the necessary CAD tool to 2n. is useless. For organizations to share designs across In 1979, a series of events catalyzed the CAD vendor various CAD and Computer-Aided Manufacturing and user community to create the first national standard (CAM) tools, their data files must be formatted in a for CAD data exchange, which is documented in the manner that the tool can recognize. -

Advances in Computer Science Research, volume 71 4th International Conference on Machinery, Materials and Information Technology Applications (ICMMITA 2016) A Feature-based Method for MBD Model Exchange among Heterogeneous CAD Systems Xie Weikang1, a, Zhao Gang1, b, Yu Yong1, c and Wang Yaodong2, d 1 School of Mechanical Engineering and Automation, Beijing University of Aeronautics and Astronautics, Beijing 100191, China; 2 Institute of Telecommunication Satellite, China Academy of Space Technology, Beijing 100094, China. [email protected], [email protected], [email protected], [email protected] Keywords: heterogeneous CAD; MBD model; feature-based; data exchange; non-geometric information. Abstract. To solve the problem that missing feature and non-geometric information when MBD (Model Based Definition) model is exchanged among heterogeneous CAD systems, a feature-based heterogeneous MBD model exchange method is proposed considering geometric feature information, non-geometric information and the association between them. Firstly, use a neutral format to express the feature information and non-geometric information of MBD model and the association between them. Secondly, transform the geometric feature information and engineering note information at the same time and maintain the relationship between them through information extraction and reconstruction by using XML (Extensible Markup Language) file as neutral format. Finally, exchange a structural model of a certain type of aircraft between Pro/E and CATIA to verify the validity of the method. 1. Introduction With the rapid development of economic globalization and digitalization technology, collaborative design for complex product by distributed in different locations, belong to different enterprises or departments has become a trend [1]. In the process of product collaborative design, due to reasons of function or economy, different enterprises or departments often choose various CAD systems. -

Until recently, standards for CAD data exchange among different CAD systems were restricted to the exchange of pure shape information. These standards ignored the parameters, constraints, features, and other elements of ‘design intent’ present in the model to be transferred. This paper suggests an implementational foundation for CAD data exchange with parametric information for the preservation of design intent, based on the use of newly published parts of the International Standard ISO 10303, which is informally known as STEP – STandard for Exchange of Product model data. A case study is presented, which employs a hypothetical STEP application protocol (AP) using Parts 55, 108 and 111 of ISO 10303. -

This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/ Title: A Survey on 3D CAD Model Quality Assurance and Testing Tools 1. Introduction According to the SASIG Guidelines for the Global Automotive Industry, “good product data quality means providing the right data to the right people at the right time [1].” Because the design field is so inherently rich in information, it is necessary to implement systems that can efficiently and securely track, control, manage, and share these data. Product data is an umbrella term that includes many different types of information. In this paper, we specifically focus on 3D CAD models. In this context, CAD model quality is a key concept, as the quality of a manufactured product depends on the quality of its design processes, which then depend on the quality of their data [2]. High quality product data is essential, as low quality often delays product development, and can negatively impact the overall quality of the final product [1,3]. In this paper, we provide an examination of CAD Model Quality Testing (MQT) tools and techniques, which are used in situations where CAD models contain errors or anomalies (in most cases, unnoticeable to the user) that can hinder simplification, interoperability, and/or reusability.
