Setting Direction Modifier Parameters
This procedure assumes you have already drawn a Direction Modifier and the 'Edit Direction Modifier <name>' dialog box is displayed.
To set Direction Modifier parameters:
- Enter a name for the Direction Modifier in the Name box (or leave it as it is if you are happy with the existing name).

- Change target – you will need to link the Direction Modifier to other targets for this to work. If you choose this, you will need to select either Specify Links or Revert to final destination. If you choose the former, you will need to specify links on the Links tab; if you choose the latter, Entities will continue to their Final Destination.
- Change final destination – you will need to add Final Destinations to the Direction Modifier for this to work.
- In the Scope portion of
the dialog, enter a percentage value between 0 and 100 in the box labelled
Percentage of entities to affect.
- For Direction Modifiers associated with Availability Profiles, percentages apply to the numbers of Entities within them.
- For Direction Modifiers associated with Event Profiles, percentages apply to the numbers of Entities specified by their Event Profiles every time-step, regardless of the number of Entities in the Direction Modifiers.
