<h2 id="curve-axis-vector-5240">
  Curve, Axis, Vector, 5.24.0
</h2>

Computes the signed distance from a planar curve to an axis. The curve must behave like a function relative to the axis, meaning it has exactly one output distance for each input along the axis.

### Inputs

| Name | Type | Description |
| - | - | - |
| Curve | [Curve](../../../../block-documentation/types/curve) | The input 3D curve (must be planar with the axis). |
| Axis | [Axis](../../../../block-documentation/types/axis) | The axis to measure from. |
| Direction | [Vector](../../../../block-documentation/types/vector) | The direction along which to measure the distance. |

### Outputs

| Type |
| - |
| [Scalar Field](../../../../block-documentation/types/scalar-field) |
