# FE Region by CAD Body

Create an FE Region of mesh elements using a CAD Body.

### Inputs

| Name      | Type                                                       | Description                                                                                                                           |
| --------- | ---------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| Cad body  | [CAD Body](../../../../block-documentation/types/cad-body) | The input CAD Body. Mesh elements inside the body will be included in the output region.                                              |
| Mesh      | [FE Mesh](../../../../block-documentation/types/fe-mesh)   | The input FE Mesh to search for mesh entities.                                                                                        |
| Entity    | FE Interior Region Enum                                    | The type of element to select in the region.                                                                                          |
| Reverse   | [Bool](../../../../block-documentation/types/bool)         | An option to reverse the selection to be outside the body instead of inside.                                                          |
| Tolerance | [Scalar](../../../../block-documentation/types/scalar)     | The search tolerance for finding mesh elements. If this function does not detect the desired elements, try increasing this tolerance. |

### Outputs
