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)

• 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?
