Drawing review

01

Turn review into visible context

Every note, measurement, count, and stamp lives on the drawing so reviewers can see the decision in context.

02

Review together in real time

Share a workspace by email or a copyable link and mark up the same drawings at the same time — presence avatars show who is in the workspace and live named cursors show where they are pointing, so a review call happens on the sheet instead of over screenshots.

03

Reduce handoff ambiguity

Marked-up exports make it easier to show what changed, what was checked, and what still needs clarification.

04

What a review round leaves behind

A useful review is auditable after the fact. Each markup change is recorded in the workspace activity log with who made it, so "who moved that dimension" has an answer; markups save automatically seconds after you stop drawing, so a dropped connection on site doesn't lose the round; and snapshots preserve the pre-review state, so a markup pass that went wrong is a restore rather than an argument. That trail — not the pen tools — is what separates review software from a PDF editor with comments.
