Windchill Aerospace and Defense configuration management methodology uses Windchill parts (WTParts) to manage object types, relationships, and functionality.

In order to address the needs of your site, you can modify the existing out-of-the-box part subtypes or create your own subtypes, if necessary. For more information about the Windchill Aerospace and Defense product and parts structure, base part types, and part subtypes, see Configuration Management Objects: Windchill Parts.
