A process is a Creo Parametric assembly that contains the features defining the manufacturing steps. It follows the naming convention process_name.asm. A process assembly has dependencies on one or more workpieces and design models.

A process allows assembly and manipulation of entire reference models relative to other models in the process assembly. A user can create a partially complete manufacturing model and then retrieve the model into manufacturing to finish defining the machining steps and to generate the toolpath.

The system retrieves the process model in whatever state it exists at the end of the process; that is, retrieves any components and sets the last step as the active step. The system retrieves into memory all components required for the process model and displays only the components that are active from the last step.
