<instance>
The <instance> element is a child of <occurrence>. Each <instance> element in the BOM XML file corresponds to a graphic object referenced by one or more callouts in the illustration. (Graphic objects with no callouts have no <instance> element in the BOM XML file.) Attributes of the <instance> element contain the object information for the graphic object.
• If one callout references multiple graphic objects in the illustration, in the BOM XML file, the <occurrence> element for that callout <item> will contain multiple <instance> elements. However, within a single <occurrence>, all child <instance> elements must be unique. (See Example A.)
• If multiple callouts reference the same graphic object in the illustration, the <instance> element for that object appears in multiple <occurrence> elements in the BOM XML file. (See Example B.)
<instance> Syntax
<instance isoId="ID" isoName="Name" isoTip="Tip"/>
|
<instance> Attributes
|
Description
|
|
isoID
|
The object ID for the graphic object in the illustration. The isoID attribute value must match the value of the ID field in the Object info dialog box.
|
|
isoName
|
The object name for the graphic object in the illustration.
When you export an illustration to a BOM-formatted Object List, the isoName attribute value gets the value of the Name field in the Object info dialog. However, when you update the illustration from a BOM XML file, the isoName value is ignored. It cannot be used to update the Name value in the illustration.
|
|
isoTip
|
The object tip (hover tooltip) for the graphic object in the illustration.
When you export an illustration to a BOM-formatted Object List, the isoTip attribute value gets the value of the Object tip field in the Object info dialog. However, when you update the illustration from a BOM XML file, the isoTip value is ignored. It cannot be used to update the Object tip value in the illustration.

Description

|
n/a
|
<instance> has no child elements.

<instance> Example A: One Callout References Multiple Objects
In the illustration, the callout F00.SFTY-SET references two graphic objects, as a set. In the BOM XML file, the <instance> elements for AUTOID_1412:CIRCLE_CLIP and AUTOID_1366:SAFETY_WASHER are both children of a single <occurrence> element for the callout <item> F00.SFTY-SET.
<item calloutValue="F00.SFTY-SET">
<occurrence>
<instance isoId="AUTOID_1412" isoName="CIRCLE_CLIP"/>
<instance isoId="AUTOID_1366" isoName="SAFETY_WASHER"/>
</occurrence>
</item>
<instance> Example B: One Object Referenced by Multiple Callouts
In the illustration, the callouts Z43.RING-SFTY and Z49-ALT.RING-SFTY both occur once, and they both reference the same graphic object AUTOID_1379:SAFETY_RING. In the BOM XML file, the <instance> elements for CIRCLE_CLIP and SAFETY_WASHER are both children of a single <occurrence> element for the callout <item>F00.SFTY-SET.
<item calloutValue="Z43.RING-SFTY">
<occurrence>
<instance isoId="AUTOID_1379" isoName="SAFETY_RING"
isoTip="Click for safety ring specifications. Alt. available."/>
</occurrence>
</item>
<item calloutValue="Z49-ALT.RING-SFTY">
<occurrence>
<instance isoId="AUTOID_1379" isoName="SAFETY_RING"
isoTip="Click for safety ring specifications. Alt. available."/>
</occurrence>
</item>
