          Unlock More Efficient, Collaborative, and Error-Resistant Processes

          Sigmetrix solutions enhance MBD processes by optimizing tolerances within 3D models, ensuring they are a reliable, manufacturable source of product information.

          Embrace a Unified 3D Model for Streamlined Collaboration, Reduced Errors, and Enhanced Efficiency

          Model-based definition (MBD) is an approach to product development that supplements traditional 2D drawings with a comprehensive 3D digital model, containing all necessary design and manufacturing information such as dimensions, tolerances, annotations, and other specifications. MBD focuses on deploying a singular, authoritative source of information in a digital format, containing all necessary product specifications, dimensions, tolerances, and other relevant details within the “digital twin.” 

            Without MBD systems in place, organizations may experience inefficiencies, increased risk of errors, and difficulties in adapting to the demands of Industry 4.0 practices. 

          Discover the Benefits of Model-Based Definition

          Adopting model-based definition leads to more efficient, collaborative product development and manufacturing workflows, ultimately contributing to improved product quality and efficiencies.

          Single Source of Truth Deployment
          MBD serves as the foundational element that establishes a singular source for design-related information within a larger framework of a model-based enterprise (MBE), which extends to the entire engineering process, ensuring a consistent and reliable reference point from design through deployment and maintenance.
          Reduced Errors
          When all information is directly associated with the 3D model, it leads to more accurate and consistent manufacturing instructions and reduces the chances of misinterpretation and errors.
          Improved Communication
          MBD enhances communication by providing a visual, standardized platform for interdepartmental collaboration, minimizing ambiguity, while enabling efficient documentation and real-time discussions among team members.
          Efficient Design Changes
          Design changes are easier to implement throughout the development process since all information is contained within the 3D model, streamlining the revision and updating process.
          Enhanced Collaboration
          MBD facilitates collaboration within cross-functional teams and enables real-time access to up-to-date product information, fostering better teamwork and coordination.
          Faster Time to Market
          With reduced reliance on manual drawing creation and interpretation, MBD can contribute to shorter product development cycles, leading to faster time-to-market for new products.
          Cost Savings
          MBD can lead to cost savings by minimizing the need for physical prototypes, reducing errors, and streamlining the overall design and manufacturing processes.
          Digital Thread Integration
          MBD connects design, manufacturing, and quality and inspection processes, ensuring a seamless flow of information from design through production and quality control.

          Enhancing the Utilization and ROI of Your MBD Investments

          Sigmetrix helps ensure that geometric and dimensional specifications within 3D models are accurate, aligned with requirements, and easily reusable in subsequent stages of the design process. Our mechanical variation management solutions ensure that geometric and dimensional controls align with the system requirements and downstream inspection needs, verifying their proper application and semantic association for future use, while confirming their completeness and clarity to avoid any ambiguity in design. We also make your MBD implementation more efficient. Our solutions help accelerate the process of determining optimal tolerances, saving valuable time that would traditionally be spent on manual tolerance stack-up calculations. Our software helps ensure compliance within the 3D model, simplifying the specification and interpretation of tolerances.

          Aligning with GD&T, GPS, and Industry Standards for Enhanced Model-Based Definition 

          Our solutions ensure that MBD data is not only accurate but also highly usable across the entire product development process. 

          • Ensure the geometric and dimensional controls specified by GD&T and GPS standards are correctly implemented within the digital models used in MBD.
          • Assist in translating and integrating GD&T and GPS specifications into MBD models, maintaining accuracy and compliance throughout the design and engineering process.
          • Perform automated checks to verify that all necessary geometric and dimensional controls have been appropriately defined and consistent with the given requirements.
          • Minimize potential ambiguities that could arise during the design, manufacturing, or inspection processes by clearly defining the GD&T and GPS definitions within the MBD models.
          • Allow for explicit and detailed specification of geometric and dimensional controls to define tolerances, constraints, and specifications to reduce conflicting interpretations.
          • Define PMI data, including geometric dimensioning, tolerancing, annotations, and other manufacturing information directly within the 3D models used in MBD.
          • Validate PMI is accurately defined and compliant with the intended design and manufacturing requirements.
          • Ensure manufacturing instructions and annotations are readily available within the MBD framework for seamless communication throughout the product lifecycle.
          • Cross-reference and verify semantic associations within the model, ensuring that the relationships between various design parameters are accurate and logical.
          • Confirm semantic principles are applied effectively within MBD to ensure that the digital models maintain meaningful and accurate representations of design information.
