Sweep a section of an implicit body along a spine curve while two rail curves drive its width and orientation.

### Inputs

| Name   | Type                                                                 | Description                                                                                                 |
| ------ | -------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- |
| Body   | [Implicit Body](../../../../block-documentation/types/implicit-body) | Implicit body to sweep. The cross section of the body within the Start Plane will be swept along the rails. |
| Plane  | [Plane](../../../../block-documentation/types/plane)                 | Plane used to define the cross-section of the body at the start of the sweep.                               |
| Spine  | [Curve](../../../../block-documentation/types/curve)                 | Spine curve to define section plane orientation.                                                            |
| Rail 1 | [Curve](../../../../block-documentation/types/curve)                 | First rail curve to sweep along.                                                                            |
| Rail 2 | [Curve](../../../../block-documentation/types/curve)                 | Second rail curve to sweep along.                                                                           |
| Caps   | [Bool](../../../../block-documentation/types/bool)                   | If checked, closes the swept body with planar caps at the start and end of the spine.                       |

### Outputs

Sweep a Profile along a spine curve while two rail curves drive its width and orientation.

### Inputs

| Profile | [Profile](../../../../block-documentation/types/profile) | Profile to sweep along the rails.                                                     |
| Spine   | [Curve](../../../../block-documentation/types/curve)     | Spine curve to define section plane orientation.                                      |
| Rail 1  | [Curve](../../../../block-documentation/types/curve)     | First rail curve to sweep along.                                                      |
| Rail 2  | [Curve](../../../../block-documentation/types/curve)     | Second rail curve to sweep along.                                                     |
| Caps    | [Bool](../../../../block-documentation/types/bool)       | If checked, closes the swept body with planar caps at the start and end of the spine. |
