The Run Controls
Type - selects a clash type. There are four possible types of clashes:
Hard - two objects actually intersect.
Hard (Conservative) - two objects are treated as intersecting even though the geometry triangles do
not.
Note:
By default, this option is turned off. To switch it on, click Tools > Global Options. In the Options
Editor, expand the Interface node, click Developer, and select the Show Internal Properties
check box.
Clearance - two objects are treated as intersecting when they come within a specified distance of each
other. Selecting this clash type also detects any hard clashes.
You might use this type of clash when pipes need to have space for insulation around them, for
example.
Duplicates - to intersect two objects must be identical both in type and position.
This type of clash testing may be used to clash the entire model against itself. This enables you to
detect any items in the scene that may have been duplicated by mistake.
Tolerance - controls the severity of the clashes reported and the ability to filter out negligible clashes,
which can be assumed to be worked around on site. Tolerance is used for Hard, Clearance and Duplicate
types of clash test.
Link - enables you to link a clash test to TimeLiner schedule or an object animation scene.
Step - enables you to control the Interval Size to use when looking for clashes in a simulation sequence.
Start - runs the selected clash test.
Found - displays the number of clashes found.
Note:
Hidden items are not included in a clash test.
The Results Tab
The Results tab contains the list of clashes, and a number of controls to manage them.
