Nodes are displayed only for the features present in the analysis case. You can see which step-dependent features have been defined and are active in each step.

The commands that are available depend on the context, and you cannot perform an action that results in an invalid sequence of steps. For example, you cannot start a feature before the first step, and you cannot deactivate a feature if it is a dependent step for the following step.

You can double-click a feature row to edit the feature using the standard dialog box and immersive field interface. The check box in the left column deactivates the feature in all steps of the analysis case (for apps that support analysis cases and multiple steps). Deactivating a feature has the same effect as deleting the feature; however, you can reactivate a deactivated feature, but you cannot restore a deleted feature. When multiple steps are available, you can right-click a column heading and deactivate the selected step. All of the features in that step are deactivated, and any feature that starts in the step is deactivated for all subsequent steps.

Right-clicking a column heading accesses controls to sort the feature rows according to the column values or to hide or show the selected column. When you sort a step column, features created in the current step appear first, followed by the features propagated to that step. You can also filter each column to show or hide particular features. In the figure above, the scenario data is filtered to show only Restraints and Loads.
