Associating Product Data to Parts
Most employees of manufacturing companies are familiar with the part structures for products they sell. It is natural to locate product documentation by navigating the relationships from a part in the product structure to the documents about the part. For this reason, Windchill provides two forms of part-to-document connection, depending on whether the part version is described by one specific document version or the latest released document version.
Users do not need to select the type of relationship to use; it is automatically determined by the document type. Documents are connected to parts using the Described By (version-specific) or References (version-independent) relationship.
