### *class* ansys.meshing.prime.SurfaceMeshSizeScaling(model=None, factor=None, size\_range\_min=None, size\_range\_max=None, json\_data=None, \*\*kwargs)

Settings related to scaling of surface mesh size for hexcore refinement.

- **Parameters:**
    
    **model: Model**: Model to create a `SurfaceMeshSizeScaling` object with default parameters.
    
    **factor: float, optional**: Value by which size should be multiplied when the size falls within a certain range. Applicable only when size field type is set to Geometric in AutoMeshParams structure.
    
    **size\_range\_min: float, optional**: Minimum size required to apply scaling. Applicable only when size field type is set to Geometric in AutoMeshParams structure.
    
    **size\_range\_max: float, optional**: Maximum size required to apply scaling. Applicable only when size field type is set to Geometric in AutoMeshParams structure.
    
    **json\_data: dict, optional**: JSON dictionary to create a `SurfaceMeshSizeScaling` object with provided parameters.

### Examples

```pycon
&gt;&gt;&gt; surface_mesh_size_scaling = prime.SurfaceMeshSizeScaling(model = model)

```
