- 1. September 21-23, 2015 Lessons Learned Leveraging MBE into S1000D 2D Illustrations and 3D Multi-media Presenter Name: Andrew Smith Rank or Title: Technical Services Manager Organization: General Atomics Electromagnetics
- 2. Agenda Lessons Learned Leveraging MBE into S1000D 2D Illustrations and 3D Multi-media (Visualizations) • A Story of MBE Gone Right - Almost • Takeaways – Big Picture • Engineering CAD Model Reuse Across an Enterprise • File types (size, meta-data, texture, animation) • Engineering CAD to IETM & Training – Best Practices • Examples of (Engineering data) Reuse • Summary – Lessons Learned
- 3. A Story of MBE Gone Right - Almost How does a company design, engineer, manufacture, assemble, test and deliver a multi-million dollar product that has major components produced from four different production plants which are spread across four nations? Establish thorough Model Based Engineering processes Murphy’s law always sneaks into the equation: October 2006, lessons learned while leveraging MBE from engineering design to manufacturing: • A major aircraft assembly plant used the latest version of CAD s/w, the design center at the factory used an older incompatible version. This small oversight resulted in 530 km of cables throughout the system having to be redesigned. Although no orders for the system were cancelled, the manufacturer still had to pay millions in late delivery penalties.
- 4. Takeaways – Big Picture • Invest in dedicated MBE processes • Drive business re-use of engineering data • Create the Return on Investment (ROI) • Contract requirements vs. expectations • One single ‘Source File of Truth’ for reuse
- 5. Engineering CAD Model Reuse Across an Enterprise • Engineering – Engineering Initial Design – Logistics for Maintainability, model QA checks, and LSA Data development • Business Development – Presentations, Brochures, Conference Displays, Posters • Peculiar Support Equipment Design/Fitment • Manufacturing/ Installation/ Integration/ Depot – Fabrication/CNC – Manufacturing Instructions (Component assembly instructions) – Integration Floor (Assembly floor instructions) – Depot Remanufacture/ Refurbishment • Technical Manuals (IETP), 2D/3D/ Wire Tracing • Training Interactive Courseware or Media Instruction
- 6. File Types (Size, Meta- Data, Texture, Animation) Using same native 3D CAD model for multiple output files for reuse across an enterprise; File Type Comparisons (Where Used) File Size 150 MB 84 MB 28 MB Uncompressed 3D Visualization 29 MB 3D Animated Visualization - IETM, Training 10 MB 2D Vector (IETM, Training) 0.7 MB Digital Video (Training) 20 MB Static Digital Image – Color or B/W (Business) 2.5 MB
- 7. Engineering CAD to IETM & Training – Best Practices Native 3D CAD 2D CAD Common Source 3D CAD (ASM, PRT) Compressed 3D CAD (STP) Intermediate file conversion(s) (WRL, OBJ, IGES, name your XYZ file) Remove unwanted test and analysis data (gravity, weight, flex, wind resistance, thermal information) 3D Visualization (name your XYZ file) Remove no-value added geometry (sub-assemblies hidden from view, extra lines, finishes (paint, film), or consumables) Restructure product structure (BOM), Set visual parameters (material, lighting) Static Digital Image - Color (JPG, PNG) 2D Vector (CGM) Static Digital Image – Black & White (JPG, PNG) 3D Animated Visualization Digital Video (HTML5, AVI, MOV, WMV)
- 8. Examples of Reuse • Native 3D CAD • Intermediate file (un/compressed) • 3D Visualization (uncompressed) • 3D Animated Visualization (AVI) • 3D Interactive Visualization (HTML5) • 2D Vector (CGM) • Digital Video • Static Digital Image (Color or B/W)
- 9. Summary – Lessons Learned • Dedicated MBE process – where/how does the business want to re-use engineering data? – Where’s the ROI? • Contract requirements – pass down – What are the customers expectations? – Negotiations for requirements/expectations? – Keep the end game in mind. Expectations aren’t always covered by contract requirements. – Draw a clear path from start to finish to include business processes. – Ensure requirement and process pass-down to sub-contractors, what is the business expecting to receive? Drawings, models, STP/ DWGs? • Engineering design – Source data is upmost importance to avoid re-work/ penalties?
Editor's Notes
- #4: Source – Wikipedia – Initial production of the A380 was troubled by delays attributed to the 530 km (330 mi) of wiring in each aircraft. Airbus cited as underlying causes the complexity of the cabin wiring (98,000 wires and 40,000 connectors), its concurrent design and production, the high degree of customization for each airline, and failures of configuration management and change control. The German and Spanish Airbus facilities continued to use CATIA version 4, while British and French sites migrated to version 5. This caused overall configuration management problems, at least in part because wiring harnesses manufactured using aluminium rather than copper conductors necessitated special design rules including non-standard dimensions and bend radii; these were not easily transferred between versions of the software.
- #5: This presentation is to drive business discussions and decisions as to level of MBE reuse within an Enterprise. Crawl-Walk-Run.
- #6: Typical business processes have a gap in the middle between Engineering, and technical manuals and training
- #7: Business processes/departments which can leverage the same source Engineering data and the formats to accomplish that reuse.
- #8: Progression of leveraging the same source Engineering data and the formats to accomplish reuse across the Enterprise.
- #9: File examples developed from the same source Engineering data and used across the Enterprise.
- #10: Lessons Learned in order to Leverage MBE into S1000D 2D Illustrations and 3D Multi-media.
