#### *static* QuadToSplineParams.set\_default(feature\_capture\_type=None, feature\_angle=None, corner\_angle=None, shell\_thickness=None, solid\_shell=None, separate\_by\_zone=None, zone\_name\_shell\_thickness\_pairs=None, project\_on\_geometry=None, use\_projection\_scope=None, projection\_scope=None)

Set the default values of the `QuadToSplineParams` object.

- **Parameters:****feature\_capture\_type: SplineFeatureCaptureType, optional**: Feature capture options.
    
    **feature\_angle: float, optional**: Angle to capture the feature.
    
    **corner\_angle: float, optional**: Corner angle of the feature.
    
    **shell\_thickness: float, optional**: Thickness of shell.
    
    **solid\_shell: bool, optional**: Solid shell option. Set true to generate solid shell spline, and set false to generate surface spline.
    
    **separate\_by\_zone: bool, optional**: Option to separate IGA shell regions by zone. If set to true, it creates LS-Dyna part per zone while exporting IGA .k file and if set to false, it creates a single LS-Dyna part per Prime part, irrespective of the zones.
    
    **zone\_name\_shell\_thickness\_pairs: Dict\[str, Union\[str, int, float, bool\]\], optional**: Zone name and thickness pair list. For example, {“Zone1Name”: Zone1Thickness, “Zone2Name”: Zone2Thickness, …}.
    
    **project\_on\_geometry: bool, optional**: Option to project on geometry.
    
    **use\_projection\_scope: bool, optional**: Option to use projection scope.
    
    **projection\_scope: ScopeDefinition, optional**: Scope to evaluate entities for projection.
