Modifying Individual Scenarios

When first created, a scenario is identical to its parent. To modify or run a scenario, it must first be made in the current Workspace scenario by selecting it within the Scenario Manager window, then clicking on the Load As Current Scenario button.  (The name of the current scenario is displayed in both the Scenario Manager window and in AFT Fathoms Status Bar.) Once a scenario is the current scenario, changes may be made to differentiate it from its parent using any of AFT Fathoms editing tools and functions. When an attribute is changed within a scenario, it breaks the link for this attribute. Subsequent changes in the scenarios ancestors will no longer affect this attribute.

Properties of a scenario that may differ from its ancestors include:

Model Data Control and User Options apply to all scenarios.
