### *class* ansys.meshing.prime.MeshStackerParams(model=None, origin=None, direction=None, lateral\_defeature\_tolerance=None, stacking\_defeature\_tolerance=None, max\_offset\_size=None, size\_control\_ids=None, seed\_faces=None, delete\_base=None, json\_data=None, \*\*kwargs)

Input parameters associated with the mesh stacker operations.

- **Parameters:**
    
    **model: Model**: Model to create a `MeshStackerParams` object with default parameters.
    
    **origin: Iterable\[float\], optional**: Origin coordinate list of stacker.
    
    **direction: Iterable\[float\], optional**: Direction vector of stacker.
    
    **lateral\_defeature\_tolerance: float, optional**: Absolute lateral distance tolerance for stacker. If the lateral distance tolerance is not specified, a default tolerance value is calculated by stacker.
    
    **stacking\_defeature\_tolerance: float, optional**: Absolute stacking distance tolerance for stacker. If the stacking distance tolerance is not specified, a default tolerance value is calculated by stacker.
    
    **max\_offset\_size: float, optional**: Maximum stack size allowed during stacking. If the maximum stack size is not specified, it is set to global max size.
    
    **size\_control\_ids: Iterable\[int\], optional**: List of size control ids to be respected by stacker. Stacker respects all supported controls by default.
    
    **seed\_faces: Iterable\[int\], optional**: List of faces whose edges need to be imprinted on the base face. If the faces are meshed, the mesh will be transferred to the base face.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **delete\_base: bool, optional**: Option to delete base face at the end of stacking. The default is false.
    
    **json\_data: dict, optional**: JSON dictionary to create a `MeshStackerParams` object with provided parameters.

### Examples

```pycon
>>> mesh_stacker_params = prime.MeshStackerParams(model = model)
