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
2012\custom_clash_tests. See Search Directories (page 159) 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 (page 674) 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.
Default Clash Rules
The following ignore clash rules are built-in:
■ Items in Same Layer - any items found clashing that are in the same
layer are not reported in the results.
■ Items in Same Group/Block/Cell - any items found clashing that are
in the same group (or inserted block) are not reported in the results.
■ Items in Same File - any items found clashing that are in the same file
(either externally referenced or appended) are not reported in the results.
■ Items in Same Composite Object - any items found clashing that are
part of the same composite object (an item composed of multiple parts of
geometry) are not reported in the results.
