4 Be sure the active tasks are attached to geometry objects, and click the Simulate tab.
5 Click t he Play
button.
The TimeLiner window displays the tasks as they are carried out, and the Scene Area shows the sections of
the model added or removed over time, in accordance with the task types.
NOTE When the Simulate tab is in use, by default the current simulation date is overlaid in the Scene Area. You can
customize the displayed information by using the
Overlay Text Dialog Box.
Configure Simulations
You can adjust both the simulation playback parameters, and the simulation appearance.
Simulation Playback
By default, the playback duration of the simulation is set to 20 seconds, regardless of the duration of the tasks.
You can adjust the simulation duration, and a number of other playback options to increase the effectiveness
of your simulation.
To adjust a simulation playback
1 If the TimeLiner window is not already open, click Tools ➤ TimeLiner.
2 Click the Simulation tab, and click the Settings button.
3 When the
Simulation Settings Dialog Box opens, modify the playback settings, and click OK.
Simulation Appearance
Each task has a task type associated with it, which specifies how the items attached to the task are treated (and
displayed) at the start and end of the task during simulation. The available options are:
■ None - the items attached to the task will not change.
■ Hide - the items attached to the task will be hidden.
■ Model Appearance - the items attached to the task will be displayed as they are defined in the model. This
may be the original CAD colors or, if you have applied color and transparency overrides in Autodesk Navisworks
or materials in Presenter, then these will be displayed.
■ Appearance Definitions - enables you to choose from the list of Appearance Definitions, including ten
predefined appearances and any custom appearances you have added.
To add a task type definition
1 If the TimeLiner window is not already open, click Tools ➤ TimeLiner.
2 Click the Configure tab, right-click in the Task Types area, and click Add on the shortcut menu.
3 A new task type is added to the bottom of the list; it will be highlighted, enabling you to enter a new name
for it.
4 Use the drop-down buttons to the right of each of the Appearance field to assign the desired object behavior.
You can customize the following properties:
■ Start Appearance - how the items will look at the start of the task, for example Transparent Green.
■ End Appearance - how the items will look when the task is completed, for example Hidden.
