**This is a beta parameter**. **The behavior and name may change in the future**.

**generate\_quads: bool, optional**

Option to generate quadrilateral surface mesh.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**project\_on\_geometry: bool, optional**

Option to project on geometry when meshing.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**delete\_interior\_nodes\_params: DeleteInteriorNodesParams, optional**

Parameters to control delete interior nodes operation.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**json\_data: dict, optional**

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