Chapter 48. Overview of Clash Detective
The Clash Detective tool enables effective identification, inspection, and reporting of interference clash in
a 3D project model.
Using Clash Detective can help you to reduce the risk of human error during model inspections.
Clash Detective can be used as a one-off 'sanity check' for a completed design work, or it can be used as
an ongoing audit check of the project.
You can use Clash Detective to conduct clash tests between traditional 3D geometry (triangles), and
laser-scanned point clouds.
You can combine the Clash Detective functionality with other NavisWorks tools:
• Linking Clash Detective and Object Animation together gives you the ability to automatically check
interferences between moving objects. For example, linking a Clash Detective test to an existing
animation scene would automatically highlight clashes for both static and moving objects during the
animation, e.g. a crane rotating through the top of a building, a delivery lorry colliding with a
workgroup, etc.
• Linking Clash Detective and TimeLiner together enables the time-based clash checks on the project.
See Chapter 51, Selecting Items for Testing for further details on time-based clashing.
• Linking Clash Detective, TimeLiner, and Object Animation, together enables clash testing of fully
animated TimeLiner schedules.
Working with the Clash Detective Window
The Clash Detective window enables you to set up the rules and options for your clash tests, view the
results, sort them and produce clash reports.
By default, the Clash Detective window floats in the main NavisWorks window. Like all other floating
windows, Clash Detective window is dockable and resizable, and will automatically lock to specific
locations near to where it is moved. You can prevent it from docking while you drag it, by holding down
Ctrl.
Note:
You can quickly dock and undock any floating window by double-clicking the window's control
bar.
To open the Clash Detective window, select Clash Detective from the Tools menu.
