Project models can include the static representation of temporary items, such as work packages, ships,
cranes, installations etc. Such static objects should be added into the TimeLiner project and scheduled to
appear and disappear at particular locations, over specific period of time.
As these static package objects 'move' around a project site, based on a TimeLiner schedule, it is
possible that some static package objects could, at some point in the schedule, take up the same space,
i.e. 'clash'.
Setting up time-based clashing enables the automated checking of this throughout the project lifetime.
When a time-based clash session is run, at each step of TimeLiner sequence, Clash Detective is used to
check if a clash has occurred. If it has, a date of when the clash took place is logged, along with the event
that caused the clash.
You can review the clash results and, for example, reschedule objects' appearance to eliminate such
clashes.
Preparation:
1. Each static package that you want to use needs to be modelled in the project model covering the
area or volume required; for example, you can use semi-transparent blocks.
2. These static packages must be added as tasks to the TimeLiner schedule.
3. Extra task types should be added to TimeLiner (on the Configure tab) to represent different types of
static packages. You also need to configure the appearance for each added task type.
To link to a TimeLiner schedule:
1. In NavisWorks open the project model file, which contains the TimeLiner schedule with the static
package tasks.
2. If the TimeLiner window is not already open, select Tools > TimeLiner from the menu bar.
3. Click the Tasks tab, and check the static package tasks are displayed.
4. Click the Configure tab, and check the task types have been added to match the static packages.
5. Click the Simulation tab, and play the simulation to view the static packages being displayed. Check
that they are shown in the correct location and over the correct periods of time.
6. If the Clash Detective window is not already open, select Tools > Clash Detective from the menu
bar.
7. Click the Select tab.
8. In the Left and Right panes, select the objects you want to test.
9. In the Link drop-down box, select TimeLiner.
10. Click the Start button. Clash Detective will check at each interval in the project to see if there are
any clashes present. The number of found clashes is displayed in the Found field.
