Scenarios can be used to model variations of a network simultaneously without the need to create separate branched networks.

For example, scenarios can be a very useful tool if used to investigate the impact of different parameters (pipe size, pipe material, for example) on simulations.

Working with Scenarios

As scenarios are derived from a base network, they do not appear in the Explorer Window as separate entities but are saved within the base network and are viewed by opening the base network and selecting the scenario to be viewed from the Scenarios Toolbar.

Any changes made to the base network are copied to scenarios.


If changes are made to a field of a network object in a scenario so that the value of the field in the scenario differs from the value of the field in the base, subsequent changes in the base network to the same field will NOT be carried over to that scenario.

If changes are subsequently made to the same field in the scenario so that the value of the field in the scenario is set to the same as the base, the link between the objects in the base and scenario is re-established and changes made in the base will be visible in the scenario again.

Network objects present in the base network but not in the current scenario are displayed as a faded grey colour in the scenario GeoPlan window. Display of these 'object ghosts' can be turned on/off from the Visual Page of the GeoPlan Properties Dialog.
