### *class* ansys.meshing.prime.SubtractZoneletsParams(model=None, retain\_cutter=None, extract\_edges=None, trace\_edges=None, json\_data=None, \*\*kwargs)

Parameters to use when subtracting zonelets.

- **Parameters:**
    
    **model: Model**: Model to create a `SubtractZoneletsParams` object with default parameters.
    
    **retain\_cutter: bool, optional**: Retain the zonelets used for removal.
    
    **extract\_edges: bool, optional**: Extract edges of intersection during subtract.
    
    **trace\_edges: bool, optional**: Trace edges of intersection on target. Only works if extractEdges is true.
    
    **json\_data: dict, optional**: JSON dictionary to create a `SubtractZoneletsParams` object with provided parameters.

### Examples

```pycon
>>> subtract_zonelets_params = prime.SubtractZoneletsParams(model = model)

```
