Today's fast paced product market has shorter lifecycles and tighter budgetary concerns. Tolerance analysis software provides an ideal solution to reduce the number of crucial steps needed to optimize a product at the design step itself. 3DCS Variation Analyst is the world's most used tolerance analysis software that is fully integrated into NX/ CATIA V5/ Creo and CAD Neutral Multi-CAD. 3DCS Variation Analyst is designed to use a consistent format and set of mathematical formulae that create reliable results, enabling engineers to gain a complete insight into their design. The software empowers design engineers to control variation and optimize their designs to account for inherent process and part variation, which in turn reduces non-conformance, scrap, rework and other associated costs. 3DCS Variation Analyst Used by the world’s leading manufacturing OEM’s to reduce the cost of quality, 3DCS Variation Analyst comes in two flavours: 1) 3DCS Variation Analyst (NX / CAA V5 or Creo Based) is an integrated solution for NX / CATIA V5 or Creo. Since it is an integrated solution, users can not only activate 3DCS workbenches from within the modelling solution, they can use many of its inbuilt functionality to support their modelling. 3DCS Variation Analyst provides three analysis methods: Monte Carlo Analysis High-Low-Mean (Sensitivity Analysis) and Geofactor Analysis (Relationship)

15. Repair, Rework, Scrap -Familiar
Scenarios?.....
What We Do When We find
•Excess Material needs to be removed from Mating Parts
•Unexpected Distortion observed in Parts Leading to Mismatch
•Locating Pins and Holes are Not Matching
•Gaps and Flush More or Less than Expected Leading to Impaired Aesthetics or
Functionality
•Interference Between Parts which Affect Smooth Motion
We Measure, Repair, Rework, Scrap…….
In short
We Waste Time, Money and Effort to
Match ‘As Built’ Quality with ‘As Designed’ Quality
Do We Want to ‘Do It Right The First Time’?

20. Why Tolerance Analysis?
• Improve both Visual and Mechanical Quality of your
product
• Determine Optimum Gap and Flush
• Optimize your Manufacturing and Assembly Processes to
determine optimum methods and order.
• Reduce Overall Variation by compensating for it in design
• Control Rework and Scrap Through robust design and GD&T
• Resolve Manufacturing Issues using measurement data
from the plant and comparing with Design data
