Managing Model Items
You are able to select a feature–such as an annotation element, or a piece of geometry– within a given Creo Parametric model and designate the feature. At the same time as designating the feature, you have the ability of specifying whether this designated feature should be considered a key characteristic.
Alternatively, you are able to specify whether the model item to be created in Windchill should be considered a BOM item, which will convey to Windchill that a corresponding part be created and represented in the product structure after a build.
