# Brush Class
 
Base class for Graphics Mill for .NET brushes.
 
**Namespace:** [Aurigma.GraphicsMill.Drawing](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Drawing.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
Public MustInherit Class Brush _Implements ICloneable
```
 
```csharp
public abstract class Brush : ICloneable
```
 
## Remarks
  
This class is abstract, so you cannot directly instantiate it. You should create some of derived classes (e.g. [SolidBrush](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Drawing_SolidBrush.htm.md) or [HatchBrush](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Drawing_HatchBrush.htm.md)). You can also cast some brush classes from [System.Drawing](http://msdn2.microsoft.com/en-us/xs6ftd89) namespace (and vice versa).
 
You can get an invisible brush (which actually do nothing) using [Empty](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Drawing_Brush_Empty.htm.md) property. To check whether the brush is empty, use property [IsEmpty](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Drawing_Brush_IsEmpty.htm.md).
