Interference Detection Input
Use command line syntax to define items to include and exclude from a query.
Inclusions
After you define the test type, define items to include in the query:
<clashDefinition>
<clashParams> … </clashParams>
<inclusions>… one or more items can be specified here </inclusions>
For standard mode, each inclusion item is in its own tag:
<inclusions>
<inclusion selfIntersect="false" id="id3" >
<soft minAllowableClearance=".05"/>
<groupref name="HotParts"/>
</inclusion>
<inclusion selfIntersect="false" id="id4">
<groupref name="ColdParts"/>
</inclusion>
<inclusion selfIntersect="false" id="id5" >
<soft minAllowableClearance=".03"/>
<groupref name="WarmParts" />
</inclusion>
</inclusions>
• Inclusion tags can contain a predefined child, as well as an optional soft tag with minAllowableClearance attribute.
• Inclusion tags can contain multiple groupref or partref that are treated as a single group.
|
|
If clashes occur for these inputs with multiple references, Creo View does not determine a top-level item.
|
To treat multiple items as a group when a Creo View group does not exist, you can use multiple partref in the inclusion instead of a single groupref:
|
|
• All item ids must be in the inclusion section.
• The order of item ids is unimportant, meaning (id0, id1, c1) is the same as (id1, id0, c1).
• An item pair shouldn’t appear more than once.
• For 2 sets of inputs, item1 and item2 must be in different sets.
|
Clearance
You can set clearance values that are global, per input, or per input pair. These clearance values are hierarchical.
• If two clearances of the same hierarchy are specified, the larger of the two values is applied.
• When defining clearance, the most specific clearance is applied automatically.
• If no specific clearance value is found, the minAllowableClearance value as defined per PVC file in the global clearance definition is applied.
<clashParams mode="QUICK">
<hard maxAllowablePenetration="0" active="true"/>
<soft minAllowableClearance="0.3" active="true"/>
<touch tolerance="0" active="true"/>
</clashParams>
To define clearance for pairs of groups, use the perPairClearances tag:
After the <inclusions> section, you can add Per Input Pair clearance inside <clashDefinition>:
If there are multiple group pairs with Pair Clearance:
• Use the maximum clearance value between all group pairs.
• Use Per Input Pair clearance and ignore other clearance types.
Exclusions
You can exclude instances of specific items from the query:
• Exclude Group — A set of groups that does not send any potential pairs to the clash engine:
<exclusions>… one or more items can be specified here </exclusions>
<clashDefinition>
• Group Pair — A pair of groups. To define pairs of groups, use this argument:
<exclusion>
<grouppair>
<grouprefname=”Small”>
<grouprefname=”Soft”>
</grouppair>
</exclusion>
• Parts Pair – An exact pair of parts as defined by idpath. You can add excluded pairs to existing results and recalculate them.
|
|
• Inclusions are mandatory. A query must contain at least one <inclusion> definition. Inclusions contain an ID created by the XML.
• Exclusions are optional and can be omitted if there are no items to exclude. Exclusions do not have an ID.
