■ Clearance. Choose this option if you want the clash test to check for
geometry within a specific distance from other geometry (see
tolerance
(page 839) 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 If the Clash Detective window is not already open, 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
(page 690)) appear at the end of the list.
3 Enter the Tolerance required, which will be in
Display Units (page 157).
See
Clash Detective Terminology (page 833) 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
(page 698).
Time-Based and Soft Clash Testing
Linking to a TimeLiner schedule integrates the features of Clash Detective
and TimeLiner together, allowing the automation of interference checking
throughout the lifecycle of a TimeLiner project.
Similarly, linking to an object animation scene integrates the features of Clash
Detective and Object Animation giving you the ability to automatically
check interferences between moving objects.
