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 etc.
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 etc. 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.
Preparation:
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 should be created by using the Animator window in
NavisWorks.
To link to Object Animation:
1. In NavisWorks open the project model file, which contains the object animation scenes.
2. If the Animator window is not already open, select Tools > Animator from the menu bar.
3. Play the animation. Check that the animated objects are shown in the correct location, in the correct
size etc.
4. If the Clash Detective window is not already open, select Tools > Clash Detective from the menu
bar.
5. Click the Select tab.
6. In the Left and Right panes, select the objects you want to test.
