If the Clash Detective window is not already open, click Home tab Tools panel Clash Detective.
On the Select tab, select the test you want to run from the Type drop-down list. Any custom clash tests that have been defined (see Create Custom Clash Tests) appear at the end of the list.
If you want to run a time-based or soft clash test, select the appropriate option in the Link box. For example, selecting TimeLiner will make Clash Detective produce a clash report based on the Clash Detective settings, TimeLiner simulation settings, and the project data contained in TimeLiner. For more information and usage examples, see Time-Based and Soft Clash Testing.
