Chapter 44. 4D Simulation
In this section, you will learn how to play 4D simulations, and how to customize the simulation playback
and appearance.
Playing Simulations
To play a simulation:
1. If the TimeLiner window is not already open, select Tools > TimeLiner from the menu bar.
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.
4. Be sure the active tasks are attached to geometry objects, and click the Simulate tab.
5. Click the Play button.
The TimeLiner window displays the tasks as they are carried out, and the main NavisWorks window
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 on the main
NavisWorks window. You can customize the displayed information by using the Overlay Text
dialog box.
Configuring 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, select Tools > TimeLiner from the menu bar.
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.
