“…Furthermore, the exact procedures, associated implementation costs, and practical steps that can lead companies to these savings need to be formally established. Nevertheless, the adoption of MBE practices has become a reality in industry, as shown by the increasing number of companies that are transitioning to model-based paperless environments [26]. In this paper, we focus on the proper communication of design information within MBE environments.…”

Revista:Computer-Aided Design Versión / Versió: Preprint Cita bibliográfica / Cita bibliogràfica (ISO 690):CAMBA, Jorge, et al. Extended 3D annotations as a new mechanism to explicitly communicate geometric design intent and increase CAD model reusability. ComputerAided Design, 2014, vol. 57, p. 61-73 AbstractA successful implementation of the Model-Based Enterprise concept (MBE) requires maximizing the potential benefits of annotated 3D models. The foundations of the MBE model are established by digital product definition data practices, which are currently regulated by standards such as ASME Y14. 41-2003 and ISO 16792:2006. At the center of the MBE concept is the notion of CAD model reusability, which relies on the idea that 3D CAD models can be reused both throughout the entire product lifecycle and as a starting point for future development of new products. In this context, a critical aspect of CAD model reuse is the proper identification and understanding of the geometric design intent that is usually expressed implicitly within the CAD model.In this work, we present a method to communicate geometric design intent explicitly by overloading and extending the scope of the current annotation instruments available in the MBE approach. We propose a new broader type of model annotation that we call "extended annotation," where design information is represented both internally within the 3D model and externally, on a separate repository. This structure naturally demands additional mechanisms to support the interaction of users with the information. In order to manage the information stored in these extended annotations effectively, we implemented an annotation manager that automatically synchronizes the dual representation of the annotations. To reduce the visual clutter in the 3D model, the software provides powerful filtering, editing, and visualization capabilities, giving users complete control of the information stored in the model. Finally, a study was conducted with 60 participants to evaluate the performance of the proposed model and the usability of the annotation manager. Results show a statistically significant benefit of using the extended annotation system, suggesting the use of this model as a valuable approach to improve design intent communication.

“…It is important that manufacturability information given to them should be in a language understandable to them. Many manufacturing and architecture industries still make use of traditional paper and 2D engineering drawings to convey design intent (Gott, 2003;Lubell, Chen, Horst, Frechette, & Huang, 2012;Opsahl, 2013). Studies have shown that modality of information affects performance and workload of humans (Cao, Theune, & Nijholt, 2009;Tavanti & Lind, 2001;Kashihara, 2009;Gîrbacia, 2012).…”

The aim of the study is to develop and evaluate a prototype designer feedback tool to give manufacturability feedback information to design engineers early at the conceptual design stage. Providing design engineers early manufacturability information on their designs helps them to improve manufacturing quality of their designs thus reducing the overall cost and lead time to manufacture. The Three Dimensional Integrated Feedback (3DIF) system is designed to be a manufacturing visualization feedback tool that is generalizable, automated, usable, inexpensive and portable. Feedback given to design engineers can be in various modalities, including verbal, text, 2D drawings, or 3D. Information abstraction and modality significantly affect its interpretation, so it is important that feedback given to the design engineers should be in the language understandable to them and is able to convey necessary information with minimal interpretation. An experiment has been designed to evaluate performance and workload differences between expert and novice design engineers when they conduct design tasks in feedback modalities. The preliminary results from the study show that providing feedback in 3D improves the manufacturing quality of the end design with lower overall cognitive workload.

“…The Model-Based Engineering (MBE) paradigm is an approach to product development that uses CAD models rather than documents as the data source for all engineering activities throughout the product life cycle. The core idea is that models can be used to drive all aspects of the product lifecycle and data is created once and reused by all downstream stakeholders [Lubell et al, 2012]. This means that all the required engineering information is communicated to everyone from one source, the digital model.…”

ACKNOWLEDGEMENTSI would like to express my deepest gratitude and appreciation to my advisor, Professor Dr. Manuel Contero, for his expert guidance, support, and valuable suggestions and critiques to this work. Thank you for accepting me as your PhD student and giving me the opportunity to work with you. I honestly could not have asked for a better advisor.I also thank my family for their love, patience, and support throughout this process and for letting me steal their valuable time to work on this dissertation. It is my hope that their sacrifice has finally paid off. ABSTRACTDespite the evolution of technologies intended to facilitate and optimize product development processes and foster collaboration, effective reuse of 3D models remains one of the biggest challenges in the area of ComputerAided Design. Whether a manufacturer is designing a new commercial aircraft or a household appliance, engineering teams often start with existing designs and adapt them to new cases, rather than designing every product from scratch. Nevertheless, CAD model reuse is not effectively supported by conventional CAD packages, as much of the burden related to reusability lies on the CAD user.It has been shown that CAD model reusability largely depends on a proper definition and communication of the geometric design intent, which are usually expressed implicitly within the CAD model. This implicit representation makes it difficult for CAD users interacting with a CAD model to understand how and why the model was created in a specific manner. This is especially true for models being reworked by designers that are not the original creators of the models. The inability to understand and modify existing CAD models negatively affects reusability and hinders the collaborative design process. The problem becomes more relevant in modelbased engineering environments, where 3D models are used as the main shared data source for all engineering activities throughout the product life cycle.Recent research has explored the potential of 3D annotations as tools to carry design intent information. The focus of this doctoral research is to study the effectiveness of 3D CAD annotation techniques to support the explicit representation and communication of design intent, and to analyze the impact of these techniques in the alteration and reutilization of 3D models in a product design context. Literature shows that a good and structured methodology is an essential step to create parametric models that are reusable and can be altered easily. However, when models reach a certain level of complexity in terms of number of features and interdependencies, additional mechanisms must be established so design intent can be communicated effectively in an explicit manner. In this regard, a comparative study was conducted to determine the complexity of three professionally accepted modeling methodologies. These methodologies represent a group of well tested and documented methodologies that are currently available to the public. An efficient 5 modeling methodology c...
