Windchill is highly customizable and provides various mechanisms and APIs to customize business logic, user interfaces, and services and infrastructure. The topics that follow document these mechanisms, making it possible to do everything, from minimally tailoring user interfaces to creating brand new business objects with supporting user interfaces and server-side logic.

This chapter provides a “Hello, World!” introduction to Windchill customization by introducing a new subtype of an existing business object and backing the user interface. The example assumes familiarity with Java and the Eclipse IDE.
