Graphic attributes defining this object are listed in the following enumeration esriGeometricEffectAttributes.

Geometric Effect is a dynamic process that alters the geometry of feature representations. Effects can be added to either a basic symbol layer or at a representation rule level making it globally applicable to all symbol layers present for that rule to create complex symbols. 

This geometric effect can be managed by one of the following graphic attributes:

Width is the thickness of the donut from the outside to the inside. For example, if width = 0 then the thickness of the donut is 0 and resulting geometry will have zero area.

The Donut method can be selected from one of the following options:
