• Hard (Conservative). This option performs the same clash test as Hard, however it additionally
applies a conservative intersection method. See Intersection Method for more information on this.
Note:
This clash test type is only available when in Developer profile. See “ Profiles ” for more
information.
• Clearance. Choose this option if you wish the clash test to check for geometry within a set distance
from other geometry (see Clash Tolerance for information on how to set this distance). You might use
this type of clash when pipes need to have space for insulation around them, for example.
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. NavisWorks Clash Detective supports soft clash checking
when you link it to Object Animation.
• Duplicates. Choose this option if you wish the clash test to detect for duplicate geometry. You might
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. On the Select tab, click the Type drop-down, and select the clash test type you wish to run. Any
custom clash tests that have been defined (see Creating custom clash tests) appear at the end of the
list.
2. Enter the Tolerance required, which will be in scene units. See Clash Tolerance for more information
on this.
3. If you want to run a time-based or soft clash test, select the appropriate option in the Link field. 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”.
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.
Finally, you can link to an animated TimeLiner schedule (a schedule in which some tasks are linked to
animation scenes), and run automatic time-based soft clash tests.
