Revision check
Know what changed in a new issue — before it becomes a variation.
The moment a new issue lands, the revision agent pairs every sheet with its previous issue and lists each change, clouded or not. Your team reviews the changes instead of re-reading the set.
≈ 3,900 hours backa year — about $591k of senior time.

A day on site
Tuesday, 5 pm: Rev D of a 48-sheet set arrives. Twelve sheets changed; two edits on A101 have no cloud. By 5:30 the RFI is drafted and the review is signed.
Illustrative scenario.
Questions
What is an unclouded change?
A change to a drawing that was not marked with a revision cloud. They are easy to miss and often surface later as variations.
Do I upload the two revisions myself?
No. When a new set arrives, ParitySense finds the previous issue of each drawing and runs the revision check automatically.
Does it replace my review?
No. It shows candidate changes with their location and confidence; you decide what each one means.
