### *class* ansys.meshing.prime.TetMeshSplineParams(model=None, feature\_angle=None, mode=None, decimation\_factor=None, json\_data=None, \*\*kwargs)

Parameters for meshing the solid spline.

**Parameters:**

**model: Model**

Model to create a `TetMeshSplineParams` object with default parameters.

**feature\_angle: float, optional**

Feature angle used in meshing of the solid spline.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**mode: TrimmedSolidSplineCutMode, optional**

Cut mode to specify rule for mesh cell selection in the volume mesh.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**decimation\_factor: float, optional**

Decimation factor used in meshing of the trimmed solid spline.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**json\_data: dict, optional**

JSON dictionary to create a `TetMeshSplineParams` object with provided parameters.

### Examples

```pycon
>>> tet_mesh_spline_params = prime.TetMeshSplineParams(model = model)

```
