Part Types
The Windchill Aerospace and Defense configuration management methodology uses out-of-the-box part types that include all of the properties and attributes that facilitate the product configuration management of WADM.
The following is a list of the out-of-the-box part types:
Base Upper Level Part
Base Configuration Item
Base Link Object
Base Design Solution
Base Lower Level Part
* 
WADM supports the Link Object out of the box, but additional configuration is necessary. For more information, see Configuring the System to Employ the Link Object.
These part types are not instantiable. This means that when you create a new part, you cannot assign it one of the base types. Rather, subtypes represent the actual business objects being managed. Subtypes are children of the base part types and inherit the necessary properties and attributes.
When you create a new part, you select one of the instantiable subtypes to assign to the new part from the Type menu in the New Part window. The subtype determines the necessary properties and attributes for that part. For example, if you are creating a new lower-level part, you select Type > Lower Level Part. The Lower Level Part subtype has inherited properties and attributes from the Base Lower Level Part type and passes those properties and attributes to the new part.
