A part is a database object that represents a physical component or assembly in the product structure of a manufactured product. A part is used as the context for all information that describes or defines that component (for example, CAD models, worksheets, drawings, and document images). The object is used to construct product structures in Windchill. Specifically, the database object type is wt.part.WTPart. For simplicity, in Windchill the WTPart object is displayed to the user as a part. Likewise, the topics in this section use the term part to refer to the WTPart object type.
