### *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)

```
