Build Tasks from Links
To build tasks from a link
1 If the TimeLiner window is not already open, click Tools ➤ TimeLiner.
2 In the TimeLiner window, the Links tab, right-click the link you want to use, and click Rebuild Task Hierarchy
from Link on the shortcut menu.
This will import all of the tasks from the project file into TimeLiner.
3 Click the Tasks tab to view the created tasks. The task table is populated in accordance with predefined
settings for the data source. You can make any necessary overrides in the Field Selector Dialog Box.
NOTE Although the tasks have now been imported into TimeLiner, you still need to Attach Tasks to Geometry before
you can run a 4D simulation. The fastest way to attach linked tasks is by applying rules (see “
Use Rules to Attach Tasks”
on page 358).
Synchronize Tasks with Project Changes
One of the benefits of linking the model to an external project schedule is that any changes to the schedule can
be easily updated in TimeLiner.
To synchronize tasks
1 Make changes to the project in the scheduling software, and save it.
2 Load your model into Autodesk Navisworks (see
Open Files if you need help).
3 Click Tools ➤ TimeLiner, and click the Links tab in the TimeLiner window.
4 Right-click the link to the modified project file, and click one of the following options:
■ Rebuild Task Hierarchy from Link. Choose this to re-import all tasks and associated data from the selected
project file, and rebuild the task hierarchy on the Tasks tab.
■ Synchronize Tasks from Link. Choose this to update all existing tasks in the Tasks tab, with the latest
associated data from the selected project file (for example, Start and End dates).
Alternatively, right-click anywhere in the link view, and click Rebuild Task Hierarchy from All Links.
This enables you to re-import all tasks and associated data from all linked project files, and rebuild the task
hierarchy on the Tasks tab.
4D Simulation
In this section, you will learn how to play 4D simulations, and how to customize the simulation playback and
appearance.
Play Simulations
To play a simulation
1 If the TimeLiner window is not already open, click Tools ➤ TimeLiner.
2 On the Tasks tab select the Active check box for all tasks that you want to include in the simulation.
3 Be sure the active tasks are assigned the correct
Task Types.
