# IDesigner Interface
 
This interface is implemented by all designers.
 
**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 Interface IDesigner
```
 
```csharp
public interface IDesigner
```
 
## Remarks
  
Each v-object has an associated designer. Designers are helper objects, intermediate between the container and their corresponding v-objects. The designers handle user input forwarded from the [IVObjectHost](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_IVObjectHost.htm.md) control and change their corresponding objects based on that input.
