2. Overview • Why MBD ? • Risk • Benefits • Future of MBD-”Smart Models” • Quality Information Framework-QIF • Summary and conclusion • Questions\Comments

3. Why model based definition ? • Move away from 2-D paper drawings • Smart 3-D Models • PMI • GD&T • Aerospace, military, automotive • NIST developing QIF with DMSC, manufactures and software vendors

4. Risks to MBD implementation • Culture of organization • Documentation • FAA rules and regulations • Advisory circular No: 21-48 • Used to describe electronic modeling system • If used must be in its entirety • Adequate replacement for 2-D paper prints

5. Concerns when developing an MBD environment • Data accessibility • Data content • Data presentation to standards • Data management • Data security • Data retention

6. Many benefits to MBD • Viewed in a common platform • PDF viewer • Keep cost down for OEM suppliers and vendors • Fully annotated model • Defining a common methodology for CAD techniques across internal and external supply chain

7. Levels of annotation • As model develops definition becomes rich with data • Will become the standard • 2-D paper prints no longer needed • Can be made for convenience during transition • Annotations to models added in steps

8. Level 1-minimal annotation • Envelope dimensions (overall boundary dimensions of the part) • “Block” or profile tolerance as applied to the entire part • Material and finish requirements • Title block information

9. Level 2-partial annotation • Envelope dimensions • “Block” or profile tolerance • Material and finish requirements • Title block information • Non-standard dimensions • Site map • Critical notes

10. Level 3-full annotation • Envelope dimensions • “Block” or profile tolerance • Material and finish requirements • Title block information • Full dimensions • Site map • Full notes • Auxiliary views

11. MBD working environment • Large amount of engineering knowledge captured in model • Complete annotated model avoids ambiguities • Reverse engineering of legacy products • Manufacturing\Inspection programming saving will show significant benefits

12. Smart models • All inclusive data set of product • Programming speed increased • Interoperability standards being developed • Associativity of all entities

13. Quality Information Framework-QIF • DMSC & NIST helping to develop standard • Holistic and integrated set of information models • QIF development of standards • Quality Measurement Plans-QMPlans • Quality Measurement Rules-QMRules • Quality Measurement Results-QMResults

14. QIF development • Ensure interoperability • Any information for manufacture or inspection • Semantic connections • Provide a platform that is easy for everyone to access and understand

15. Summary • Many transitioning to MBD • Collaboration between operations, engineering, and supply chain • Reduces labor costs, quality losses • Enterprise agility • Lower product costs • Culture changes top down • Model is final normative of part definition

16. Conclusion • Best practices developed and followed • All in supply chain need to be on board • Communication of intent is vital • No surprises • Every effort to help all involved • Correct path for future business • Reliable and accessible data for supply chain
