Through the feature Tree Outline, you can suppress and unsuppress features. When a feature is suppressed, that means it is ignored when the model is generated. There are four suppression options, though only two of the four are available at a time.
Suppress: Suppresses the selected
feature and features that depend on it.
Unsuppress: Unsuppresses the selected
feature and all features that it depends on.
Suppress & All Below: Suppresses
the selected feature and all features below it in the feature Tree Outline.
Unsuppress & All Below: Unsuppresses
the selected feature, all features below it in the feature Tree Outline, and all features that they depend on.
