Import a PDF drawing set, mark it up, measure, compare revisions and track review comments — all in your browser. Keep the set local to this machine, or start a private project and invite reviewers by email.
Drawing Review
Runs in the browser — nothing to install.
| Input | PDF drawing sets |
| Output | Markups, measures, revision compare |

How it works
The drawings are opened in your browser, so a local workspace never uploads them. Markups, measurements and comments are saved alongside the set; a private project uploads the PDFs only so the reviewers you invite can open them.
- PDFs are read in the browser and stay on your machine in a local workspace.
- Markups, measurements and comments attach to their sheet and save as you work.
- Revision compare puts two sheets side by side and boxes what changed.
- Exports are written in the browser; the local workspace is never uploaded.
Using it
Import the drawings
Click Import drawings or drop PDFs onto the canvas, then pick, reorder and label sheets in the drawing set.
Mark up
Choose a tool from the dock — Comment, Cloud, Arrow, Pen, Note, plus Line, Rectangle, Ellipse and Highlight — and draw on the sheet.
Measure and calibrate
Set the drawing scale, then measure Length, Polyline, Area or Count on the sheet.
Track the issues
Place an issue with the Comment tool, assign it, and follow replies in the Issues view or the comments panel.
Compare revisions
In the Compare tab, pick the sheet to compare with and use Overlay, Swipe or Difference; Cloud them turns detected changes into tracked markups.
Import returned comments
Bring a consultant's marked-up PDF back in and fold its comments and markups into the set.
Export or share
Export a marked-up PDF, a clean set, per-sheet or per-discipline ZIPs, a comment report or a register — then share the project with invited reviewers.
What to trust it for
- Running a drawing review without printing the set.
- Marking up a consultant's PDFs and tracking who said what.
- Spotting what changed between two revisions of a sheet.
- Collecting every comment and markup into one record.
What not to use it for
- Editing the drawings themselves — this marks them up, it does not redraw them.
- A substitute for a coordinated BIM model review.
- Legal or contractual sign-off.
Known limits
- Markup precision is screen precision; set the scale before trusting a measurement.
- Revision compare flags visual candidates, so always confirm a change.
- A local workspace lives only in this browser; a private project is what shares it.
Tips
- Do — Calibrate the scale on each drawing before measuring — the numbers depend on it.
- Do — Use the Stamp and Sign tools to place status stamps and a signature on the sheet.
- Avoid — In a private project, reviewers must sign in with the exact email you invite — a link alone does not grant access.
