Remarks

IOverride interface can be used to access override information for a feature representation. While the feature representation can have both shape and attribute overrides, this interface is used to access attribute override information only.

Attribute overrides are overrides made to graphical attributes for LineStroke, GradientPattern, LinePattern, SolidColorPattern, BasicMarkerSymbol, all marker placements, all geometric effects and visibility property which can be retrieved using IRepresentationClass::GraphicAttributes property.

When an attribute override exists for a feature representation, HasAttributeOverride property returns True.

RemoveOverride method can be used to remove override present on a specific graphical attribute given its index.

To remove all overrides present use RemoveOverrides method. However, this method cannot be used to remove shape overrides. Use IRepresentation::RemoveShapeOverride method to remove shape overrides.
