2.
Analyzer: An equation based analysis output that precisely
identifies the amount and source of variation within an assembly.
Optimizer: A tool for optimizing tolerances to achieve best quality
based on a minimal cost or optimize quality based on a fixed
budget.

3DCS Advanced Analyzer creates an equation of the entire
3DCS model and displays the inputs (contributors/tolerances)
and outputs (measurement results) and their relationships
(Coefficients of Influence) in a graphical interactive matrix .
3DCS Advanced Analyzer/Optimizer Module
How does Analyzer work?
1. Tolerance changes can be made in a graphical
interactive matrix providing instantaneous feedback
of updated results.

2. Analysis
Results are viewed in Numerical or
Graphical format.
3. Using a color-coded matrix of the Sensitivity Index,
user can interactively emphasize contributors that
are of great importance to the measurements.

Optimizer Overview
3DCS Advanced Analyzer/Optimizer Module
What does Optimizer do?
Optimize tolerances to achieve best quality at a minimum
cost.
–
2.
Allocate largest possible tolerances (larger tolerance = less cost)
while still meeting dimensional objectives.
Optimize quality for a given fixed budget.
–
Optimizer
Allocate largest possible tolerance at the least amount of cost to
achieve “Target Cost”. In this case it may be possible that
dimensional objectives are not met.

3DCS Advanced Analyzer/Optimizer Module
How does Optimizer work?
User inputs tolerance cost, as well as the total system cost based on
calculation method, and the Optimizer will automatically solve for optimized
tolerances and validate feasibility.

What are the Benefits of Analyzer?
• Real time analysis
– Quickly change tolerances and view new analysis results from a
global perspective instantly – no need to re-run simulations
– Sensitivity Index (Coefficients of influence) quickly identifies where
design is sensitive to variation
– Influence design decision making process before tooling kickoff
• Analysis at any level within the assembly process
– Efficiently drill down through the assembly process to pinpoint the
exact source of variation
