Pro/E Pro/Program
Each model in Pro/ENGINEER contains a listing of major design steps and parameters that can be edited to work as a program. By running the program, you change the model according to new design specifications.
To enter the Pro/PROGRAM environment, click Tools > Program from the PART or ASSEMBLY menu.
Initially, you can gain access to only a design listing that exists in the model. However, whenever you edit a listing, a file is created that contains the latest design specifications. At this point, two design listings exist for the same model, From Model and From File. After you successfully incorporate design changes in the model, From File is deleted, and only From Model is available.
