What is QC Mode in PDFDepth?

The review chain on a stamp

The stamp models the plan-review table used on DOT-style plan sets: a company name, a subtitle naming the loop, and one row per step. Steps run in order — a row is locked until the step before it is signed off, and the panel shows progress as it fills in.

• Origination — the originator assembles the plans; any markup color allowed.
• Checked — first-pass review: yellow marks correct work, red flags errors and questions.
• Concurrence — a second reviewer agrees in green or logs disagreements in red.
• Changes Made — the originator highlights each agreed change in yellow.
• Changes Verified — a different person blue-checks that each change was actually made.

Sharing and assigning the review

Turning the mode on the first time creates the stamp and opens the share dialog, so the set is uploaded and reviewers join through the ?doc= collaboration link. Because the stamp is a synced annotation, initials and dates fill in live for everyone looking at the document — there is no "send me your copy" step.

Each step can carry an assignee (initials, up to four characters). Only the assignee — or the stamp’s owner — can sign that step off. The stamp itself is restyled from the panel: company name, subtitle, and a choice of ink colors.

Color discipline is enforced, not suggested

While a step is active, new markups are coerced into that step’s ink — highlights, clouds, lines, text notes, and pins included. Check and X stamps carry protocol meaning, so a check always lands in the step’s "agreement" ink and an X in its "disagreement" ink even if you picked another color. Drawing a red cloud during Concurrence is not possible by accident.

What it is — and is not

The stamp is an annotation on page 1: it travels with the document and flattens into the output on export like any other markup. A sign-off writes initials and a date onto the stamp row — it is a review record, not a cryptographic signature. For the drawing-by-drawing content checks, pair it with AI Plan Review, which flags candidate issues with sheet citations while QC Mode tracks who verified what.

Doing it in PDFDepth

Right panel → Quality Check Mode. The first toggle drops the stamp and opens sharing; "Share for QC review" re-shows the link later, and "Copy link" puts it on the clipboard. Set the company name and ink, assign each step, and have each reviewer sign off in turn.
