Feature filters are filters that define the features (construction elements) to be revised.
Feature filters are created in two situations:
1.As a filter that applies to a feature relevant task:
Feature filters can be accessed via the filter node menu in the feature filter dialog.
2.As a filter that defines a feature filter node in an enhanced filter:
Feature filters can be accessed in the Feature exists filter node. The feature filter editor opens under Edit feature filter.
Feature Filter for feature-relevant tasks
The Feature filter is executed for a specific task.
–Example: The Suppress Feature task is performed for all features of the “Component” type.
–Feature filters play a special role in this function: Alongside report filters, they are the only filters that are defined within a task (in the Task lists menu item).

2. Feature Filter for Feature Filter nodes
The feature filter defines the filter node Feature Exists in an extended filter and only performs a task for the defined feature(s)
–Example: The filter Feature Exists applies to the Rename View task: The view is renamed for all features of the type “Pipe.”
–If you create the filter node Feature Exists in the filter tree, you can access the feature filter editor using the Feature Filter Editor command.
