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.
To prepare for time-based clashing
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 must 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 Autodesk 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, click Tools ➤ TimeLiner.
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 they
are shown in the correct location and over the correct periods of time.
6 If the Clash Detective window is not already open, click Tools ➤ Clash Detective.
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 box.
NOTE If the TimeLiner project is large in size, running this type of clash test will invariably take more time to
complete than a normal clash run.
You can now review the found clashes.
Soft Clashing
Project models can include the dynamic representation of temporary items, such as work packages, ships, cranes,
installations, and so on.
You can use the Animator window to create animation scenes with these objects, so that they will be moving
around a project site, or change their size, and so on. It is possible that some moving objects could collide.
Setting up soft clashing enables the automated checking of this. When a soft clash session is run, at each step
of a scene sequence, Clash Detective is used to check if a clash has occurred. If it has, a time 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' movement to eliminate such clashes.
To prepare for soft-clashing
1 Each object that you want to animate needs to be modelled in the project model covering the area or volume
required; for example, you can use semi-transparent blocks.
2 Animated scenes with the desired objects must be created by using the Animator window in Autodesk
Navisworks.
