Input of Items for Interference Detection
Use the following items as input in an Interference Detection query.
• Parts
• Assemblies
• 
Groups—Dynamic or Static
Input can be grouped in these ways:
• Self Intersection—Checks interferences inside assemblies and groups. The default state of Self Intersection for assemblies and groups is selected.
• 
—Divides the input into two groups to test for interferences between them.
You can optionally select items to exclude from the query.
Setting Specific Clearances
When Clearance is queried, you can optionally set a specific Clearance value for each input item. Each input item can have a specific clearance value. The input to interference consists of items that reference parts, assemblies, or predefined groups. Some parts can belong to several input items.
• This value must be larger than the Tolerable Distance.
• If a part does not belong to any input item with specific clearance, then the part clearance is the global clearance.
• A part can belong to more than one item, and can have multiple specific clearances according to the items to which it belongs, in which case the largest of the clearance values is used.
• When calculating the clearance between two instances, the larger value between the two (whether its global or specific) is applied.
