Description
The IFeatureClassDraw interface is an optional interface for feature class extensions, used to specify custom drawing behavior in ArcMap.
When To Use
Before a FeatureLayer draws features in a feature class, it will check the FeatureClassExtension for support of this interface. Custom drawing can be achieved through the use of a custom renderer or through the use of a custom feature that implements IFeatureDraw::Draw.

Remarks
If using a custom renderer, the ExclusiveCustomRenderer property can be used to restrict the available renderers to the custom one for the feature class. If the custom renderer is configurable, a configuration property page can be specified with the CustomRendererPropPageCLSID property. If using a custom feature and that feature utilizes extra fields beyond the Shape for drawing, it is necessary to specify those fields in the RequiredFieldsForDraw property or they will not be returned in the FeatureLayers FeatureCursor.
