## About this Block

**What it does:** The **Refine Bounding Box** block refines the bounding box of an implicit body based on a given tolerance. This step ensures that the bounding box fits the body properly, often after performing boolean operations.

**Common uses:**

* Calculate a tight bounding box.

Refines the Bounding Box of an Implicit Body given a Grid Size.

### Inputs

| Name      | Type                                                                 | Description                                                                                                                               |

| Body      | [Implicit Body](../../../../block-documentation/types/implicit-body) | Refines the bounding box of this Body.                                                                                                    |
| Grid size | [Scalar](../../../../block-documentation/types/scalar)               | Size of the sample grid spacing. As this value gets smaller, the resulting Bounding Box will be tighter, but will take longer to compute. |

### Outputs

| Type                                                                 |
