The problem: changes that miss affected parts

An engineering change can touch many parts and drawings. Updating them one by one risks missing some.

A port size change looks small, but it touches the part, its drawings and every assembly that uses it. When each record is updated separately, one drawing is easy to miss, and the mismatch shows up on the shop floor.

What this demo shows

  1. Open change order ECO-1042, which enlarges the VB-40 outlet port from 3/4 in to 1 in to match a new skid layout.
  2. Review and sign the change.
  3. Release it, with every affected part and drawing updated together.

‍

Why it matters

An engineering change order that lists every affected part keeps the change complete. Reviewers see the full scope before signing, not one record at a time.

Releasing the change updates every affected part and drawing together, so the next build uses consistent information and the change history shows exactly what moved and when.

Release it and every affected part locks against edits. And each part page lists the change orders that name it. Every change traced. One PLM suite.
