Setting Application Options
The system application options are defined in the EZTAAppOptions.xml file.
The default location of this file is in the …\Common Files\applications\EZTOL folder in the Creo Parametric installation folder.
The config.pro option ezta_app_options_file enables you to set the path to the application options file if you want to store the file in a location other than the default location mentioned above.
This XML file contains three primary elements: Audio, Default Values, and Display State. Note that if you edit the EZTAAppOptions.xml file, you must stop and restart EZ Tolerance Analysis for the changes to take effect.
Audio
The Audio element controls whether the camera shutter sound is played when you press 
in the stackup table to save a snapshot of the current view.
in the stackup table to save a snapshot of the current view.Values can be either true or false.
Default Values
The default values element contains the following sub-elements:
Analysis Type
This element corresponds to the Analysis Type option in the Options dialog box.
Values can be WorstCaseAnalysisType, RSSAnalysisType, or StatisticalAnalysisType.
If the analysis type is set to StatisticalAnalysisType, then the values under the QualityMetric element (see below) are used to determine the quality metric and default value.
Cp Value
This element controls the default value of the Model Cp associated with the Statistical analysis type that will be used for new models.
This is the value for Model Cp that appears in the Optionsdialog box when a model is opened in EZ Tolerance Analysis for the first time. Subsequent changes made to the Model Cp value in the Options dialog will only affect the current model and are not saved in the EZTAAppOptions.xml file.
Draft Angle
This element controls the maximum allowed draft angle for drafted features of size, such as drafted slab, drafted slot, drafted shaft, or drafted hole.
See Working with Drafted Features of Size for additional details.
Tolerance
This element contains sub-elements that control the default tolerance values for linear dimensions, size dimensions, and geometric tolerances in both Metric and US Customary unit systems.
Quality Metric
This element contains the sub-elements that control the default quality metric and value that are used if the analysis type is set to Statistical.
The values for Type can be SigmaUnits, CpkUnits, DpmoUnits, and PercentYieldUnits.
Each type has a corresponding element to control the value used for that quality metric type.
Display State
The display state element contains the following sub-elements:
List Table Widths
This element controls the column widths of the Stackup Table if the summary view of all stackups is shown.
Loop Table Widths
This element controls the column widths of the Stackup Table when the detail view of a selected stackup is shown.
Non 1D Warnings
These sub elements control whether the message warning that the calculated results of the stackup are ignoring potentially significant 3D effects is enabled or disabled in both the user interface and the report.
Options
The MigrateFromRegistry sub element contains a flag that instructs the application to read any EZ Tolerance Analysis settings that might be stored in the Windows Registry and then migrate those settings to the EZTAAppOptions.xml file.
If this element is not present or if it is set to true, then the application reads the Windows Registry settings and migrates them to the EZTAAppOptions.xml file. This typically happens when running Creo Parametric 11 or later for the first time if an earlier version of Creo Parametric was previously installed.
If this element is present and set to false, then the application does not read the settings from the Windows Registry but instead continues to read the settings from the EZTAAppOptions.xml file.
