What a free alternative needs
The capabilities that keep people paying for Bluebeam Revu.
1
Scale-calibrated measurements and takeoff
Length, area, count and volume markups on drawings, with quantities summarized in a report.
2
Reusable tool sets
Saved markup tools with preset scale, color and subject, shared across a team.
3
Live shared review sessions
Studio sessions with check in and out, activity records and assigned markups.
4
Markup lists and status tracking
Why it is hard
Scale-accurate measurement must stay correct across PDF page sizes and rotations, and shared sessions need a collaboration service that teams on separate networks can reach.
