Extract an Implicit Body from a Topology Optimization result.

### Inputs

| Name         | Type                                                                                               | Description                                                                                                        |
| ------------ | -------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| Result       | [Topology Optimization Result](../../../../block-documentation/types/topology-optimization-result) | Result to extract surface from.                                                                                    |
| Threshold    | [Scalar](../../../../block-documentation/types/scalar)                                             | Density threshold above which all material will be kept.                                                           |
