Model Based Enterprise - Model Based Definition : Definition and Approach

Model-Based Definition (MBD) is an approach that documents a product using exclusively enriched 3D data. This system combines 3D geometry, Product Manufacturing Information (PMI), and metadata to create a single source of complete information. MBD relies on 3D annotations, including dimensions, tolerances, roughness, and other attributes essential to manufacturing. Additionally, 2D documents such as lists, diagrams, or matrices can be included in a Technical Data Package (TDP), which centralizes all the necessary information to fully define a product and its requirements.

The Advantages of MBD and MBE

The MBD approach represents a true revolution in the CAD/CAM/CAE field. Annotated 3D models and 3D TDPs are gradually replacing 2D drawings as the sole source of all design information. When an MBD approach is deployed from the early stages of the product lifecycle and reused throughout the company and its supply chain, it enables faster, more consistent, and cost-effective product development, from design to disposal.

This transformation leads to the creation of an environment called Model-Based Enterprise (MBE). In an MBE environment, MBD becomes the design reference or product authority. Transitioning from 2D drawings to a 3D model with annotations reduces errors, rework, and the costs associated with creating physical documents. Collaboration between stakeholders is optimized, and data is shared more efficiently.

Challenges in Transitioning to MBD

While the implementation of MBD is promising, it involves many challenges. Companies must not only migrate their legacy 2D/3D data but also ensure the reuse of MBD data throughout the supply chain. This requires rigorous data management and the adoption of new standards for creating and sharing 3D annotations. Technical Data Packages (TDPs) must be compatible with all CAD systems used to ensure seamless interoperability with partners and suppliers, regardless of the platforms they use.

The Importance of Data Quality in MBD

It is essential to ensure data quality in 3D models and TDPs. The goal is for all model users to share the same information unambiguously, enabling smooth and error-free collaboration. If the original design intent is faithfully maintained within the 3D model, the risk of downstream issues, especially in production, is minimized. This also reduces the need for exchanges of questions and clarifications between teams.

A Successful Digital Transformation

The transition to an MBD environment represents a major evolution for companies, offering tangible benefits in terms of productivity, efficiency, and cost reduction. However, this transition is not without challenges, and companies must ensure rigorous data management and interoperable compatibility across all their systems. Thanks to CAD Interop's interoperability solutions, this transformation becomes an opportunity for continuous improvement, enabling companies to remain competitive and optimize their processes throughout the product lifecycle.

The evolution of Technical Data Packages (TDP) has transformed the way industries manage and share their information. By transitioning from traditional 2D drawings to intelligent 3D formats such as 3Di PDF, companies now benefit from enhanced interoperability between different CAD systems. 3Di PDFs not only centralize critical design information but also make it accessible in complex workflows while ensuring data fidelity. With their universal compatibility and ability to integrate interactive annotations (PMI), 3Di PDFs have emerged as a key solution to address growing challenges in digital collaboration and standardization.

Navigating the complexities of CAD collaboration and manufacturing often feels like a high-stakes chess game. From maintaining robust models to reducing engineering errors, businesses are fraught with challenges that could potentially cost a fortune if not addressed promptly. Recent discussions with ITI partners and industry professionals confirm that while these topics are undeniably crucial, they are often sidelined due to budget constraints and a lack of expertise. What if we told you that ignoring these could lead to far graver repercussions than the cost of dealing with them? Dive in to unearth effective solutions for overcoming these hurdles and why making an early investment could save you big in the long run.

There will always be differences between the design model and the manufacturing model. Zero article inspection (ZAI^TM) answers the important and potentially costly question: Are differences between the design and manufacturing model acceptable?

Today, the evolution underway for many engineering enterprises is the implementation of 3D Model Based Design (MBD), using applications such as Catia 3D Master, where all Product Manufacturing Information (PMI) such as functional tolerances, dimensions, and annotations are stored in the 3D model rather than in the linked associative 2D drawings.

Dive into the heart of design validation by leveraging the power of 3D MBD models. Discover how robust validation can become an essential link in every phase of the product life cycle. From simulation to manufacturing and through to support, your 3D model will be the reliable foundation for all your activities. Moreover, explore how CADIQ emerges as the tool of choice for validating the quality of your geometry and your 3D PMI annotations.

The evolution of Model-Based Definition (MBD) has redefined the industrial landscape. 2D drawings are giving way to 3D models enriched with Product Manufacturing Information (PMI). 3DViewStation has emerged as a key player in this revolution, offering sophisticated tools to visualize and interact with these annotated 3D models, meeting the interoperability and complex data management requirements.
