Explicit Attributes with Creo and Windchill

I'm trying to understand if explicit attributes initially flow from Windchill into the Creo model. It seems that this is the case. Also, does identifying uppercase Creo parameter in the "Creo" field of a specific attribute (via Type Manager) make that attribute explicit?

Mike,

Specifying the name of the parameter in the Creo field in the Attribute data as you pointed out will set up explicit mapping. As Creo parameters are in upper-case then the parameter name specified in that field should also be upper case. Implicit-mapping will occur if an attribute has been associated with the CAD Document type that has the same name and case as the Creo parameter (i.e. Windchill IBA Internal name is TEST and Creo parameter name is TEST).

There are a couple of help topics in the Windchill Help Center that cover the different kinds of mapping. Info can also be found in the Using Creo Parametric with Windchill Guide.

Tom,

Specifying them at the EPM Document Master level means that the attribute values will not be file-based (i.e. all iterations of a particular CAD Document version will have the same attribute value). Additionally, only file-based attributes (those specified on EPM Document/CAD Document) will map to Creo parameters.

I am curious about this as well. Certain parameters automatically show up in the CAD model as soon as they're saved to the workspace. Others do not.

Currently we create all of our custom attributes at the CAD Document subtype level:

I've been told that if you create them at the EPM Document Master level they will automatically propagate like the other built-in Windchill parameters, but I've not had a chance to try it myself yet.

I don't think using all caps has anything to do with it.

Thanks Tom,

Your answer here helped me figure out my similar question on another thread.

Great! Thanks Lori!

I'll check into these help sources. I want to be sure that the directional flow is always from Creo to Windchill. In other words, I want to be sure that if an attribute is created in Windchill, and a corresoponding parameter for that attribute is not created in Creo, then that attribute will not be pushed into the Creo parameters table.

Windchill help states, "Implicit mapping is recommended as the preferred mapping method because otherwise released data could be changed without a new iteration being reviewed. If a change is made to an explicitly mapped attribute and then a file is downloaded, you might see a different result than before the change to the mapping was done." Does this mean that explicit mapping is the only way to go if the desire is to make changes to attributes via Windchill without iterating the EPMDocument?
