Geofactor Analyzer 
shows the relationship between each tolerance measure pair. The simplified Analysis is done using a numerical matrix format that places all tolerances and measurements in a single window.
•You have AAO_Lever_Assembly already open.
•Click 
Nominal Build.
•Click 
Run Analysis for 2000 runs (inactive floats OK) and scroll through the measurements. Note that some results are out-of-spec (red in Meas4 below). This tutorial attempts to minimize those out-of-spec samples.
•In the Advance Analyzer and Optimizer toolbar click on the GeoFactor Analyzer icon.
oClick Run Analysis from the dialog
oThe purpose of this button is to collect information from the existing 3D model to be used in calculating the matrix.
oClick OK to confirm the default File Path and the Gradient Step value. The matrix will be generated.
oNote that if the Advanced Analyzer Matrix drops to the background, Alt+Tab to bring it forward or click on the GeoFactor Analyzer icon.
oFrom this chart you can see the GeoFactors for all measures at once with their respective measured values along with the tolerance ranges and names.
oYou can display factor value or percent contribution values in the matrix by selecting Factors or Percentage from the Data Set drop-down option.
oNote that the GeoFactors of Meas4 are 1 and -2 just as shown
oThe "white" fields are editable and can be modified by double-clicking the current value and typing in a new value.
oFor more information on each function in the dialog, see Appendix section 1.1 AAO Matrix Definitions.
• Click on the Range field for 1 DCSTol1(Base_1) and change the value from 10 to 15 and hit enter.
oThis is a quick way to see the effect on Measurement range globally by changing a tolerance range.
oNote that the measurement Ranges update; for example, Meas4 Range has increased from 22.361 to 25.000(mm).
oAlso note that the color-coded GeoFactor values will not change.
➢GeoFactor coefficient are calculated based on the locators used in the moves and location of the measurements.
| If these locations do not change the coefficient will not change. |
•Highlight the 4 Meas4 column in the GeoFactor Analyzer Window and select [Show Measure] to view the measure in the graphical window. You may have to minimize the Simulation and GeoFactor Analyzer windows.
•In the GeoFactor Analyzer window again, highlight the DCSTol2 row and select [Show Tolerance] to view the tolerance in the graphical window.
•Hit 
Separate and close all windows and the current AAO_Lever_Assembly model. There is no need to save the model.
Model 2 Review: AAO_Headlamp_Assembly
GeoFactor Analyzer
•Open the AAO_Headlamp_Assembly in the tutorial folder.
The Tutorial files and the Example Models install to the following default directory:
C:\Users\Public\Public Documents\DCS\3DCS_All Platforms_8_0_0_1\Tutorials\V5MCNXV6CREO_AAO_Tutorial\Headlamp Assembly
• Nominal Build and GeoFactor Analyzer the Advanced Analyzer Matrix for the Headlamp model.
•Click "Run Analysis" to generate the colored chart. Color-coding breakdown is determined by the absolute value of the GeoFactor coefficients (minimum and maximum) globally. Ensure that Factors is selected from the Data Set drop-down.
oYou may notice that some GeoFactor values are the same but color coded differently. That is due to rounding. Click Options -> Display Options and change the Factor Precision to 10 to see the value differences; change it back to 1 when done.
oContributing tolerances with GeoFactor less than a set value are filtered out of the analysis. This will remove contributing tolerance rows that do not include any GeoFactors over the set value. Click in the Values field and replace with 2 in the field to change the set value. Contributors aren't deleted by doing this; they're just hidden from the Analyzer Matrix.
oContributing tolerance rows 1, 2, 3, and 4 are filtered out or hidden but color-coding values of the remaining rows will be the same.
oChange the Factor Value Filter back to 0
oNow Select Percentage from the drop-down next to Data Set. Each tolerance's contributing percentage is shown in the matrix and is color-coded.
oAgain, you can Filter tolerance Percentage by editing the Filter field (currently filtering contributors with less than a 10% contribution globally).
oClick and change the values for the color coding. Since there are more factors in this model, you will be able to observe the dynamic color-coding coding in the Matrix.
oChange tolerance range for any tolerance to observe the change in percentage contribution.
•Close model without saving.
Conclusions
The Advanced Analyzer Matrix is used to enter "what if" tolerance values and immediately see updated measurement results. These can be compared on a full model basis.
