Windchill WTPart structure for reference CAD part

[_Chandu_]

Need suggestion in below use case, please suggest if any OOTB option is available.

Process Steps:
1. We will create CAD document 'Type1' (actual cad part) in Creo and during Chek-in to Windchill, "Auto Associate Parts to CAD Documents" is selected so that WTParts are created in Windchill in Product1.
2. We will create CAD document 'Type2' (reference part) in Creo and during Chek-in to Windchill, "Auto Associate Parts to CAD Documents" is selected so that WTParts are created in Windchill in same Product1.
3. After Chek-in, on Details page of the CAD document, from the Actions menu, we click on "Build Associated Part" action to create Part structure (BoM).

Requirement:
1. CAD document 'Type1' should participate in the WTPart structure.
2. CAD document 'Type2' should not participate in the WTPart structure (WTPart is still linked to CAD document but will not participate in the structure).

What we already know:
We know "Owner" link drives the structure and "Contributing content" link can restrict structure. But how do we dynamically change link types during check-in? Or do we have any other OOTB method?

You can set the default auto-associate link type but there is nothing other than customization if you want this to follow some other rules. The default is owner links. If you manually auto-associate them, you are given the option to change the type. Otherwise, you can change them by editing associations from the WTPart. When you say type, are you talking about soft-types of CAD files?

Some help information on this:

Basic rule is that first one wins. If there is no CAD linked to that part or its being created on check in, it will be owner. The second item will be something other than owner.

Hello avillanueva,

Thank you for the hints. In our use case we re avoiding sub typing of CAD document.

As you say we may have to consider only customization as an option.

Hi @_Chandu_ 

you can use an IBA Attribute / Creo Parameter that drives if the WTPart can be created or if the part should be part of the BOM.

You can create the part NO_WPART on a Master object, Iteration Objeect or UsageLink

Hello HelesicPetr,

Thank you for the hints. This also helped in our other use cases.
