Create Custom Clash Tests
Exported clash tests can be used as a basis to define custom clash tests. If you have a common set of clash tests
that you reuse on multiple projects, you can turn them into a custom clash test. Once installed as a custom clash
test, the entire batch of tests can be selected and run directly from the “
Select Tab” on page 374. The results from
all tests in the batch are combined and presented as the results of the custom clash test. The name of each test
in the batch is displayed in the Description field of the results.
Custom clash tests are an excellent way to roll out a standardized set of tests across an organization. They allow
the expertise of "power" users to be reused by everyone. Finally, they can be seen as a way of implementing object
intelligence. For example, a custom clash test could be written that checked for compliance with a local building
code based on object information and properties defined in a particular CAD system.
To define and use a custom clash test
1
Export Clash Tests to an XML file. The name of the file is used as the default name for the custom test.
2 If you want, change the name of the custom test by editing the XML file directly. The top level element in
the XML file is called "batchtest". The name of the custom test as displayed to the user is defined by the
"name" attribute. The name of the custom test as saved in a file is defined by the "internal name" attribute.
3 To install the custom test, copy the exported XML file to the custom_clash_tests folder of one of the
Autodesk Navisworks search directories, for example: C:\Documents and Settings\All Users\Application
Data\Autodesk Navisworks Manage 2010\custom_clash_tests. See “Search Directories” on page 84 for
more information.
4 Restart Autodesk Navisworks. On start up, Clash Detective checks these search directories for custom clash
tests.
5 To use the custom test, open the Clash Detective window, and click the Select tab.
6 Select your custom test from the
Type drop-down box.
7 Click the Start button. All other options and rules are specified by the custom test.
Clash Rules
Using ignore clash rules reduce the number of clash results by ignoring certain combinations of clashing items.
The Clash Detective tool includes both the default clash rules and clash rule templates that can be used to create
custom clash rules.
