Parameters for defeature topology operations.

Parameters:

model: Model

Model to create a DefeatureTopologyParams object with default parameters.

partial_defeature: bool, optional

Option to partial defeature.
This is a beta parameter. The behavior and name may change in the future.

delete_interior_nodes: bool, optional

Option to delete interior nodes.
This is a beta parameter. The behavior and name may change in the future.

allow_curved_topo_faces: bool, optional

Option to allow curved topofaces.
This is a beta parameter. The behavior and name may change in the future.

fillet_spanning_angle: float, optional

Angular threshold for detecting fillets with spanning angles below the provided value.
This is a beta parameter. The behavior and name may change in the future.

aggressive_edge_merge: bool, optional

Indicate whether to allow aggressive edge merge while performing partial defeature.
This is a beta parameter. The behavior and name may change in the future.

thin_stripes_tolerance: float, optional

Topoface width tolerance to detect thin faces below the provided value.
This is a beta parameter. The behavior and name may change in the future.

partial_defeature_params: PartialDefeatureParams, optional

Parameters for partial defeature operation.
This is a beta parameter. The behavior and name may change in the future.

delete_interior_nodes_params: DeleteInteriorNodesParams, optional

Parameters for 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 DefeatureTopologyParams object with provided parameters.
