We are living a continuous and fast technology evolution, maybe this evolution goes faster than our capacity to assimilate what we can do with it, but the potential is clear and the future will be for those who identifies the right technology with the right application. The way we work with Computer Aided Design (CAD) tools is also changing thanks to the ubiquitous access to information and the different hardware available to exploit that information: Augmented Reality, Virtual Reality or Mixed Reality. Not only the way we work, but also the way we interact with CAD tools is changing, with technologies like natural language processes that allows direct conversation with the applications. The concepts that are absolutely clear from now to the future in shipbuilding are the use of Data Centric models and the concept of Digital Twin. Both provide a real and effective synchronization between what we design and what we construct, by covering the complete life cycle of the product, thanks to technologies like the Internet of Things (IoT) and Radio Frequency IDentification (RFID). Nowadays it is unimaginable to work without using CAD in shipbuilding: ease of design with design rules embedded, speed of design, and the use and reuse of information. It is expected that in the future CAD tools will advance further and allow greater information management through further improvements. The paper presents several scenarios with improvements likely to occur the next few years. Some of these improvements may seem unrealistic in the short term, but reality often exceeds expectations in any field, and probably more so with technology.

The Way

We are living a continuous and fast technology evolution, maybe this evolution goes faster than our capacity to assimilate what we can do with it, but the potential is clear and the future will be for those who identifies the right technology with the right application. In the information era, we are literally swimming in an ocean of structured and not structured data and thanks to the evolution in the Telecommunications technologies, all that information can be used from everywhere. However, information means nothing without the capability to analyze, extract conclusions and learn from it, which is way the technologies like treatment of Big Data and the Artificial Intelligence are crucial. Imagine how these technologies shall allow engaging the design of a part or any concept by applying rules, which will facilitate the design significantly, how the integration of the validation of the structural models by the Classification Societies will be linked directly by cloud applications. Imagine all the benefits of this two simple examples that can be implemented thanks to the potential of these technologies. The way we work with shipbuilding CAD tools is also changing thanks to the ubiquitous access to the information and the different hardware available to explode that information: AR, VR, MR, Smartphones, tablets, etc. Nevertheless, not only the way we work, but also the way we interact with shipbuilding CAD tools is changing, with technologies like natural language processes that allows having a direct conversation with the applications. The concepts that are absolutely clear from now to the future in shipbuilding is the use of Data Centric model and the concept of Digital Twin, a real and effective synchronization between what we design, what we construct, by covering the complete life cycle of the product thanks to technologies like IoT and RFID. This paper tries to explain the importance to understand how the new generations of naval architects and marine engineers are immersed in a technological world in constant and rapid evolution. The way they interacts with this ecosystem will determine the way we should define the new rules of the shipbuilding CAD systems.

Technologies are evolving faster than our ability to assimilate what we can do with them, but the potential is clear and the opportunity will be for those who identifies the right application of each technology. In the information era, we are literally swimming in an ocean of structured and not structured data and thanks to the evolution in the communications technologies, all that data are available everywhere for everyone. But data is not information. It is necessary to have the capability to analyse, extract conclusions and learn from it. Technologies as Big Data (BD) and the Artificial Intelligence (AI) are crucial for this purpose, but the intention of the treatment matters. Imagine how these technologies shall allow to engage the ship design by applying rules which will facilitate the design significantly, how the integration of the validation of the structural models by the Classification Societies will be linked directly by cloud applications. Imagine all the benefits of this two simple examples that can be implemented thanks to the potential of these technologies. The concepts that are absolutely clear from now to the future in shipbuilding is the use of Data Centric model and the concept of Digital Twin, a real and effective synchronization between what we design, what we construct, by covering the complete life cycle of the product thanks to technologies like IoT. It is important to understand how the new generations are immersed in a technological world in constant and rapid evolution. The way they interacts with this ecosystem will determine the way we should define the new rules of the CAD/CAM/CIM Systems. This paper examines different selected solutions describing practical use cases in ship design phase as an example of what IoT, BD or AI will represent for ship design and shipbuilding in the near future.

Contemporary architectural and urban planning aims at optimal development of the environment, including in terms of acoustics. As such, support with computer-aided design (CAD) tools is, nowadays, obligatory. The authors present investigation outcomes of three different CAD and computing methods extracted for the study. The scope covers different scales of considerations from architectural acoustics to the urban level, which relates to the standard architect’s commissions field. The described approaches are applicable for both academics and professionals in the broadly understood building industry There were analysed and synthesized experiences from the use of two-dimensional and three-dimensional simulations, computing based on standardized formulas, and an acoustic meter (here: the SVAN 979 for RT60, LAeq measurement). The article concludes with an assessment, which shows possible uses of methods and confirmations of their usability.

Abstract Computer aided design tools are gaining popularity in industry due to their ability to model the geometric aspects of products. This has shown substantial benefit for reducing the need and expense of building physical prototypes and allowing parts and tooling to be manufactured directly from these models. However, the current capabilities in existing CAD tools for modeling assemblies are quite limited. In this paper we introduce a representation for describing interfaces between parts within hierarchical assemblies for capturing functional and physical mating relations. This representation is designed to support automated reasoning and automated generation and modification of assemblies. It is also designed for use with very large assemblies, compactly representing the interfaces of parts and assemblies that are reused within larger assemblies. We describe how this representation is used in our prototype design system, Genesis, for designing aircraft systems.

Molded Interconnect Devices can be considered as attractive option for the integration of electronic functions into mechanical systems. While development methods and procedures reached high standards, CAD tools still drag behind. This paper focusses the necessary software structure for implementing of automated routing algorithms or other MID specific extensions into CAD tools. An innovative three-layer model will be introduced and explained in detail. This paper also describes a method for mapping electrical components on unfolded surfaces for the further implementation of the automated routing algorithms.

The Impact

AbstractThis paper presents a preliminary comparison between the role of computer-aided design (CAD) and sketching in engineering through a case study of a senior design project and interviews with industry and academia. The design team consisted of four senior level mechanical engineering students each with less than 1 year of professional experience are observed while completing an industry sponsored mechanical engineering capstone design project across a 17 week semester. Factors investigated include what CAD tools are used, when in the design process they are implemented, the justification for their use from the students' perspectives, the actual knowledge gained from their use, the impact on the final designed artifact, and the contributions of any sketches generated. At each design step, comparisons are made between CAD and sketching. The students implemented CAD tools at the onset of the project, generally failing to realize gains in design efficiency or effectiveness in the early conceptual phases of the design process. As the design became more concrete, the team was able to recognize clear gains in both efficiency and effectiveness through the use of computer assisted design programs. This study is augmented by interviews with novice and experienced industry users and academic instructors to align the trends observed in the case study with industry practice and educational emphasis. A disconnect in the perceived capability of CAD tools was found between novice and experienced user groups. Opinions on the importance of sketching skills differed between novice educators and novice industry professionals, suggesting that there is a change of opinion as to the importance of sketching formed when recent graduates transition from academia to industry. The results suggest that there is a need to emphasize the importance of sketching and a deeper understanding as to the true utility of CAD tools at each stage of the design process.
