What is it?What is it?3DCS Advanced Analyzer/Optimizer is an add-on module to

3DCS comprised of two core functionalities:1. Analyzer: An equation based analysis output that precisely

identifies the amount and source of variation within an assembly.

2. Optimizer: A tool for optimizing tolerances to achieve best quality based on a minimal cost or optimize quality based on a fixed budget.

How does Analyzer work?How does Analyzer work?

The 3DCS model is converted into an equation based model where:

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.

Random method Equation Based

Monte Carlo 3DCS Advanced Analysis

Predictive analysis with potentially time consuming simulation runs (depending on complexity of model).

EQUATION BASED representation of the design and manufacturing process with instantaneous results.

Deficiencies:

× Potentially time consuming

× re-run simulation each time a tolerance is modified

Benefits:

Immediate results

No need to re-run analysis after tolerance changes

Visualize input-output inter-relationships

OptimizerOptimizer

What does Optimizer do?What does Optimizer do?

1. Optimize tolerances to achieve best quality at a minimum cost.

– Allocate largest possible tolerances (larger tolerance = less cost) while still meeting dimensional objectives.

2. Optimize quality for a given fixed budget.– 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.

• Real time analysis– Quickly change tolerances and view new analysis results from a

global perspective instantly – no need to re-run simulations

• Quickly identify contributors to variation– 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
