# JointControlPointsProvider Class
 
This class represents a combination of several control points providers.
 
**Namespace:** [Aurigma.GraphicsMill.WinControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_WinControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.WinControls.VectorObjects (in Aurigma.GraphicsMill.WinControls.VectorObjects.dll)
 
## Syntax
  
```
Public Class JointControlPointsProvider _Implements IControlPointsProvider
```
 
```csharp
public class JointControlPointsProvider : IControlPointsProvider
```
 
## Remarks
  
If you want to use additional control points like, for example, nodes in polylines, you need to combine a standard control points provider with a custom one. The JointControlPointsProvider class allows to do that.
