Select Clash Test Options

There are four default clash test types for you to choose from:

• Hard. Choose this option if you want the clash test to detect actual intersections between geometry.

• Hard (Conservative). This option performs the same clash test as Hard, however, it additionally applies a conservative intersection method.

• Clearance. Choose this option if you want the clash test to check for geometry within a specific distance from other geometry (see tolerance for more information). You can use this type of clash when, for example, pipes need to have space for insulation around them.

  Note: Clearance clashes are not the same as “soft” clashes. Clearance clashes detect for static geometry coming within a distance of other geometry, whereas soft clashes detect potential clashes between moving components. Clash Detective supports soft clash checking when you link it to Object Animation.

• Duplicates. Choose this option if you want the clash test to detect for duplicate geometry. You can use this type of clash test to check a model against itself to ensure the same part has not been drawn, or referenced twice, for example.

To select the Clash Test Options:

1. Click Home tab > Tools panel > Clash Detective .
2. 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.
3. Enter the Tolerance required, which will be automatically converted to the Display Units. See Clash Detective Terminology for more information.
4. 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.
