part and job files

This may be a dumb question, but I understand the job file, but do not understand the difference between a job file and part file. They seem the same to me. The help file gives no explanation.

This can be a bit confusing. A job file contains all of your parts and settings. A part file just contains one part with it’s operations and tools. You would mainly use part files to build up a library of standard parts that you cut often. You can then easily load a number of different parts onto your sheet and nest them as desired.
