# NurbsCurveFitParameters.KinkSplit enum

Namespace: [Rhino.Geometry](https://developer.rhino3d.com/api/rhinocommon/namespace/rhino.geometry.md) · Assembly: [RhinoCommon](https://developer.rhino3d.com/api/rhinocommon/assembly/rhinocommon.md) · Since v9.0

```cs
public enum NurbsCurveFitParameters.KinkSplit
```

The KinkSplit enum is used to determine how target curve kinks (abrupt changes in target or curvature) are handled during rebuilding.

## Values

| Name | Value | Description |
| --- | --- | --- |
| None | 0 | All target curve kinks are ignored and rebuilt curves will be G2. |
| AtG1Changes | 1 | The rebuilt curve is permitted have a tangent change at locations where the target curve has tangent changes. Curvature changes in the target curve are ignored. |
| AtLargeG2Changes | 2 | The rebuilt curve is permitted have a tangent or curvature changes at locations where the target curve has a tangent or large curvature changes. |
| AtMediumG2Changes | 3 | The rebuilt curve is permitted have a tangent or curvature changes at locations where the target curve has a tangent or medium curvature changes. |
| AtSmallG2Changes | 4 | The rebuilt curve is permitted have a tangent or curvature changes at locations where the target curve has a tangent or small curvature changes. This option is the most sensitive to splitting at any tangent or curvature kink. |
