If a data model must be associated with the trajectory (to get extra settings or give specific data to the user code), select it from the drop down list.
To set or change the parameters (interface) of the data model, use the button.
For example, a trajectory might represent an exit procedure. User can then create a data model named FireEngine with all kind of data some other components or logics might need to process. Using the data model attachment capability, user will be able to specialize any trajectory of his scenario.
When end procedure is set to Inverse (13), specify here the time in seconds the entity will recede from the last point before engaging the U-turn maneuver.
