### *class* ansys.meshing.prime.DetectAndTreatCircularFacesParams(model=None, edge\_mesh\_constant\_size=None, surface\_mesh\_constant\_size=None, merge\_edge\_allow\_self\_close=None, merge\_face\_normals\_angle=None, json\_data=None, \*\*kwargs)

Parameters for detect and treat circular faces operation.

- **Parameters:**
    
    **model: Model**: Model to create a `DetectAndTreatCircularFacesParams` object with default parameters.
    
    **edge\_mesh\_constant\_size: float, optional**: Constant size used for edge meshing.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **surface\_mesh\_constant\_size: float, optional**: Constant size used for surface meshing.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **merge\_edge\_allow\_self\_close: bool, optional**: Option for merging self-closing edge loops.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **merge\_face\_normals\_angle: float, optional**: Merge faces when the normal angle between the faces is below the provided value.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **json\_data: dict, optional**: JSON dictionary to create a `DetectAndTreatCircularFacesParams` object with provided parameters.

### Examples

```pycon
&gt;&gt;&gt; detect_and_treat_circular_faces_params = prime.DetectAndTreatCircularFacesParams(model = model)

```
