“…With regard to this, Nguyen et al [18] proposed a method for reducing the size of lightweight models by representing a triangular mesh model and a B-rep model in hybrid. Furthermore, Eigner et al [19] suggested a method for using the JT file together with an XML file that contains additional information in order to improve the utilization of the JT file. Kwon et al [20] proposed adaptable lightweighting procedures of 3D CAD models considering various semantics during the lifecycle of plants.…”

One of the most widely used methods for representing the shapes of ships and offshore plants is triangular mesh, which has a simple structure and is easy to visualize. In particular, lightweight models composed of triangular meshes are often used as a sharing medium for three-dimensional (3D) shape design results in the collaboration process among many stakeholders participating in the construction process. Currently, there are demands for visualizing the total shapes of ships or offshore plants for design review, interference check, construction monitoring, and securing maintenance space. However, this requires high computing power and much time due to the large size of the triangular mesh model. We have two general solutions as follows: simplifying the shape of the ship and offshore plant structure and reducing the size of the lightweight file itself. Between them, this study proposes a method for reducing the lightweight file. This method classifies the part types of the ship or offshore plant structure and then only stores the minimum triangular mesh information for each part type, excluding unnecessary information. Then, the topographic information of triangular meshes is stored together in the lightweight file to shorten the time required for restoration of the lightweight file.

“…It can be an addition to the JT-format. [28] There are first approaches to translate complete models from one CAD-system to another [29], but those are incomplete, not standardized and the tools cannot be used to share product data with other systems besides the target CAD-system.…”

In order to develop new products, design engineers build digital product models leveraged by 3D-Computer-Aided-Design (CAD)-systems. During design, they specify various aspects of the product: e.g., which technical elements like wholes, pockets and materials the product consists of, or which tolerances have to be observed during production. This information is vital to stakeholders in subsequent processes like production planning and control as well as process engineering or quality management. Nowadays, the information is shared via the distribution of technical drawings, which implies various problems (e.g. change of media, different CAD-systems in use by different organizational units, or unnecessary overhead to retrieve the required information from the model). In order to mitigate these problems, this paper proposes an approach to extract the information that is relevant to the stakeholders from various CADsystems, and store this information in a vendorneutral format, which other application systems or employees are able to process.

“…These formats offer potential for cost savings by the reduction of license fees, to reduce time to market, and to improve interoperability in heterogeneous system landscapes. For a business strategy, the main objective is to establish one standardized data format for all engineering downstream processes [9], [10].…”

Part 9: Simulation and Virtual EnvironmentsInternational audienceIn this paper a concept for the virtual validation of automotive measurement services based on JT (ISO 14306:2012) is introduced. Each physical measuring component has a digital representation, represented by a 3D JT model. These models contain all necessary information of the measurement process and are the basis for the application of physical sensors. The developed concept enables the consistent usage of JT models and the suitable integration of virtual engineering methods into measuring services, resulting in improved efficiency and interoperability. For the implementation, instead of a CAD system, the viewing software Teamcenter Lifecycle Visualization Mockup is used. This leads to cost savings by the reduction of license fees. The concept is validated based on two measuring projects, containing separate component models and a complete vehicle model
