The Business Benefits of Adopting Model-Based Definition
Key Takeaways
- Model-Based Definition (MBD) improves engineering efficiency by including product manufacturing information (PMI) directly within 3D CAD models.
- Adopting MBD tools and practices can reduce reliance on 2D drawings, accelerate time to market, and improve collaboration across design, manufacturing, and inspection.
- MBD supports digital transformation initiatives and improves quality through fewer interpretation errors and better variation control.
For years, engineering teams were forced to rely on fragmented documentation and manual processes during product design and development. The rise of Model-Based Definition (MBD) ushered in a more intelligent and efficient way to create, share, and interpret product data.
Adopting MBD transforms product development into a faster, more accurate, and more collaborative process. Companies that adopt MBD cut costs, reduce waste, and gain a competitive edge.
What Is Model-Based Definition?
Model-Based Definition (MBD) is a modern approach to product design and manufacturing that ultimately seeks to replace traditional 2D drawings with comprehensive 3D CAD models containing all necessary Product Manufacturing Information (PMI). This embedded data covers various process and product details, including:
- Geometric Dimensioning & Tolerancing (GD&T)
- Materials
- Surface finishes
- Assembly instructions
- Inspection requirements
With PMI consolidated within the 3D model, teams gain a complete digital definition of the product and a foundation for a more connected and efficient product development process — one that delivers tangible business advantages throughout the entire product lifecycle.
Benefit #1: Cost and Time Savings from MBD Adoption
MBD saves time and money by streamlining processes and eliminating many of the inefficiencies of traditional documentation. For example:
- When PMI is included within 3D models, teams spend less time communicating design specifications across departments and suppliers.
- Fewer drawing-related clarification requests reduce delays during manufacturing and supplier interactions.
- Less time devoted to creating and updating 2D drawings accelerates project delivery.
- Faster, model-based reviews simplify design approval and engineering change workflows.
- Reduced rework and scrap lower overall production costs while improving quality and consistency.
Together, these advantages help organizations operate more efficiently and shorten lead times, allowing teams to focus on new initiatives rather than routine documentation tasks and rework.
Benefit #2: Improved Cross-Functional Collaboration
MBD creates a shared digital environment that enhances collaboration in several key ways. For example:
- Referencing the same PMI-rich model fosters transparency and alignment between design, manufacturing, and quality teams.
- Clear, data-integrated models reduce ambiguity and prevent inconsistent interpretations of tolerances or specifications.
- Early engagement from manufacturing, inspection, and supply chain teams enables better Design for Manufacturing (DFM) and Design for Assembly (DFA) decisions.
MBD breaks down silos and enables real-time feedback, fostering a more connected way of working that strengthens teamwork, speeds up decision-making, and increases overall product development quality.
Benefit #3: Enhanced Quality Through Digital GD&T
MBD elevates product quality by embedding GD&T directly within the 3D model, ensuring that specifications are clearly defined and consistently interpreted. For example:
- Including GD&T within the 3D model minimizes human interpretation errors that often occur with 2D drawings.
- Integrating GD&T within an MBD environment enables semantic PMI, which in turn supports automated inspection and verification workflows.
- Centralized, data-driven tolerance information enables better variation management across assemblies and suppliers.
This integrated approach reduces quality issues, shortens inspection cycles, and builds confidence in every stage of production.
Benefit #4: Supporting Digital Transformation Initiatives
MBD forms the foundation for broader Model-Based Enterprise (MBE) strategies that connect every phase of the product lifecycle. For example:
- MBD enables digital thread and digital twin initiatives by linking design specifications to real-world performance data.
- Integration with PLM, ERP, CAM, CMM, and MES systems ensures seamless data flow across design, manufacturing, and quality functions.
- A unified, model-centric approach reduces data redundancy and improves traceability throughout product development.
MBD serves as the cornerstone of digital transformation, helping organizations unlock smarter, more connected, and highly automated operations.
Benefit #5: Streamlined Supplier Communication
MBD improves external collaboration by streamlining the way suppliers and contract manufacturers receive and interpret product information. Sharing intelligent 3D models instead of static drawings helps organizations avoid the ambiguity and delays that typically arise from email-based clarification cycles. For example:
- With MBD, vendors and contract manufacturers spend less time resolving drawing-based interpretation issues, accelerating production readiness.
- Models exported in neutral formats like STEP 242 retain embedded PMI, ensuring accuracy and compatibility across different systems.
- Suppliers can perform simulations, toolpath generation, or inspection planning directly from the model, improving efficiency and alignment.
Adopting MBD strengthens supplier relationships, shortens response times, and helps maintain consistent product quality across the entire supply chain.
Benefit #6: Scalability and Long-Term ROI
Once implemented, MBD streamlines operations and reduces the manual effort required to maintain documentation. This long-term efficiency translates into measurable cost savings and scalability across teams, products, and regions. For example:
- MBD minimizes redundancy and versioning errors by ensuring every stakeholder works from accurate, unified data.
- Simplified auditing, compliance, and traceability processes help organizations meet industry and regulatory standards with less effort.
- A model-based approach scales easily across product lines and global engineering teams, supporting consistent processes enterprise-wide.
With predictable results, lower overhead, and continuous process improvement, MBD provides a strong foundation for sustainable growth and ongoing ROI.
How to Get Started with MBD
Adopting MBD requires a structured plan with distinct phases. The following steps can help organizations build momentum in implementing model-based practices:
- Start With Pilot Projects: Focus on key projects and assemblies that will demonstrate ROI, and use those early successes to refine workflows before scaling across the organization.
- Invest in Targeted Training: Provide design, manufacturing, and quality teams with specialized, role-specific MBD training to teach them how to interpret and use MBD data effectively.
- Ensure Standards Compliance: Select tools that align with ASME GD&T or ISO GPS standards to maintain consistency and interoperability.
- Partner With Experienced Providers: Work with vendors offering both software solutions and implementation expertise to guide your MBD journey. Partnering with a trusted provider like Sigmetrix ensures access to proven software tools and decades of experience helping organizations like yours achieve success with MBD.
Unlocking the Full Potential of MBD
Adopting Model-Based Definition improves product development speed, accuracy, and quality. As manufacturers navigate increasing product complexity and tighter timelines, MBD provides the foundation for more agile and scalable product development. It represents the future of product design, where connected data, automation, and collaboration drive quality and innovation.
