Use AAO, Advanced Analyzer and Optimizer, to quickly optimize your designs for maximum quality at the lowest cost. Excellent for quickly testing and changing many tolerances at once, AAO is a great way to speed up modeling, and more importantly, speed up the process of testing and checking new tolerance strategies. As an inexpensive add-on to any of DCS's 3DCS software suites, including the embedded CATIA versions, AAO is a simple way to save time and increase efficiency.

5. It has a lot of important measurements.
AAO Overview2
My model has dozens of tolerances.

6. What feature is my model most sensitive to?
Which tolerances contribute the most?
How can I save money?
How do I know I’m getting the
best quality for my money?

7. Where Do I Start?

8. • Quickly identifies where design is sensitive to variation
• Enhanced GeoFactor results
• Change individual tolerance ranges for instant results
• Show GeoFactor or Percentage Contribution
• Global color scaling based on adjustable sliders

*Assumption: larger tolerance = less cost

15. Measures
• Goal Value: check all spec limits, default is fine
Tolerances
• MaxTol/MinTol
– Profile, MinTol = 1.0mm
– Position, MinTol = 0.5mm
• Locking
– Tooling (no ability to change)
– Size (low influence on model)
• Cost
– Profile tolerance costs 20% of Position tolerance
– All other tolerances equal

– Profile, MinTol = 1.0mm
– Position, MinTol = 0.5mm

• Total Available Budget: estimated cost (assume unlimited to see best
quality)

21. With an “unlimited” Budget, best achievable quality is -0.412 @ $8276.25
Assume an Available Budget of $5000, quality is -0.586
After Max/MinTol Adjustments with $5000 Budget, quality is -0.436
