<strong>MBD</strong> <strong>Interoperability</strong> <strong>Challenges</strong> <strong>and</strong> <strong>Solutions</strong>Global Product Data <strong>Interoperability</strong> Summit | 2012The adoption of Model Based Definition (<strong>MBD</strong>) practices promises savings due to the elimination (or significantreduction) of CAD drawings. New <strong>MBD</strong> compliant models can be easily created <strong>and</strong> shared using today's CAD<strong>and</strong> PLM software, but what about all of the existing legacy drawing based data? Is <strong>MBD</strong> data reliable whenreused downstream? As companies develop strategies to implement <strong>MBD</strong>, questions about interoperability playa central role in planning.• How is the drawing checking function replaced?• What about all of the legacy 2D CAD drawings?• Without drawings to red line, how will engineering changes be documented?• Are lightweight visualization models (JT, 3D PDF etc...) complete <strong>and</strong> correct?• Are direct translations to other CAD formats successful?• Can we rely on neutral st<strong>and</strong>ards for translation?• What are the risks when switching CAD versions? CAD platforms?• How are archiving strategies (LOTAR) impacted?This session will highlight how migration, translation, <strong>and</strong> validation technologies are being deployed by leadingaerospace companies to address these challenges <strong>and</strong> ensure successful <strong>MBD</strong> implementations. It will alsoinclude updates on recent st<strong>and</strong>ardization initiatives within the US Department of Defense <strong>and</strong> the InternationalSt<strong>and</strong>ards Organization.BOEING is a trademark of Boeing Management CompanyCopyright © 2012 Boeing.
