The video demonstrates how work‑in‑progress files behave when moved through a PDM workflow. A part and its drawing progress from revision C in development to pre‑production approval, then into a new release where the revision increments to D. Approving the files generates an updated revision and produces a PDF automatically. The revision table updates correctly at each stage, showing history entries and maintaining consistent data. After moving to revision 01, the example shows how change numbers and reasons for change are captured when editing, checking in and progressing the files through the workflow.
