Creating a new revision
Taking a released part back into work, correctly.
Once a part is released you can't simply edit it. You create a new revision, which normally happens through a change order so there's a record of why.
The usual route — via a change order
- Raise an ECR describing the problem, or open an existing one.
- Once approved, it becomes an ECO listing the parts affected.
- Creating the ECO puts those parts into a new working revision automatically.
- Make your changes — fields, files, BOM.
- Submit the ECO for approval. On approval, the new revision releases and the previous one is superseded.
The direct route
If your company permits it, you can create a revision straight from the part's Revisions tab without a change order. Some companies disable this deliberately so every change is traceable to a request. If the option isn't there, that's why.
Writing the description
You'll be asked what changed. Write it for someone reading it in two years with no context. "Increased wall thickness 2.0 → 2.5 mm to address cracking at the boss, per ECR-2026-0014" is useful. "Updated model" is not.
A part can have exactly one open working revision. If someone else already has one open, you'll join theirs rather than starting a second — this is what stops two people revising the same part in parallel.
Email [email protected] and a person will pick it up. Include the part number and what you were doing — it saves a round trip.
