# DefaultDesigner Class
 
This class represents a designer which is used when no v-objects are selected in the viewer area.
 
**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 DefaultDesigner _Implements IDesigner, IDisposable
```
 
```csharp
public class DefaultDesigner : IDesigner, IDisposable
```
 
## Remarks
  
The default designer is used when no v-objects are selected in the viewer area. That is, if there is no current designer, the default designer processes user input.
 
This designer is responsible for the v-object selection. When the user presses a mouse button and drags a mouse, the selection rectangle appears. All v-objects inside the selection rectangle will become selected.
