Limits and review points

• RevLatch assists review; it does not certify a drawing, replace professional judgment, or guarantee that every change was found.
• Password-protected or scan-only PDFs may need preparation or manual review.

Troubleshooting

A sheet match appears wrong

1. Check the baseline and revised file selection.
2. Correct the proposed sheet pairing before interpreting any displayed difference.

Alignment is unreliable

1. Treat the pair as needing manual review.
2. Check the source PDFs and page pairing before deciding whether a change is significant.
