Stamps with your own wording, name and date; the stamped PDF opens in any viewer.

Markup and review →

Revision compare

Highlight what changed between two revisions of a drawing, even when it moved on the sheet.

How it fits

Upload the vendor’s revision as a new version of the drawing: the markups carry over, and Compare shows what changed since the last one you stamped.

Our sample sets are generated, fictional drawings made for demonstrations.
