Features

Everything you need on a drawing set. Nothing you don't.

Redpen covers review, measurement and takeoff end to end, and keeps the screen calm while you work.

Review & markup

Markups that read clearly on screen and on paper.

Clouds and cloud callouts: Revision clouds by box or by points, with or without a leader.
Callouts and arrows: Text boxes with leaders that stay attached when you move them.
Text, highlight, strikeout, underline: Mark up the drawing text itself, or type anywhere.
Shapes and pen: Rectangles, ellipses, polygons, lines, polylines and freehand.
Markups list: Every markup with author, date, status and comments. Filter, sort, group, export.
Tool chest and format painter: Save your go-to markups and copy a style from one markup to many.
Group, align, distribute: Line markups up and move sets of them together.

Get the scale right once, and every number after it is right.

Autoscale: Reads the dimension strings on the sheet, finds the lines they label and votes on the true scale. Works on reduced prints where the scale note is wrong.
Autoscale an area: Point it at one viewport when a sheet has details at different scales.
Calibrate: Click two points, type the real distance. Done.
Presets: Architectural, engineering and metric scales, per page or for the whole set.

Real-unit quantities that update as you draw.

Length and polylength: With dimension-style labels you can pull off the line.
Area, perimeter, volume: Plus cutouts for openings, and a depth for slabs and footings.
Wall area: Draw the run, set the height, get the square footage.
Angle, radius, diameter: For the odd geometry.
Snapping: Snap to line ends, midpoints and intersections on vector PDFs.
Takeoff totals: Group by subject or page with running totals in the side panel.

Fixtures, devices, piles, anything with a symbol.

Count tool: Numbered markers by group: Type A troffer 1, 2, 3...
AutoCount: Click one symbol and Redpen finds and numbers every match on the sheet.
Export: Counts go to Excel with everything else.

The PDF chores, without a second program.

Insert, extract, rotate, delete pages: Build the set you actually need to send.
Edit text: Fix a typo in the PDF itself.
OCR: Make scanned drawings searchable.
Redaction: Remove content for good, not just cover it.
Bates numbering and stamps: For submittals, closeout and claims.
Sheet overlay: Compare two revisions on top of each other.
Digital signatures and watermarks: Sign pay apps; mark sets DRAFT or VOID.
Flatten: Burn markups into the page when the file has to be final.

Set it up once, the way you work.

Bluebeam-style shortcuts: On by default, so your muscle memory still works. Remap anything.
Customizable toolbar: Arrange and hide tools; workspaces for review or takeoff.
Themes: Dark, light, dimmed and high-contrast.
Command bar: Type the name of any command and run it.
Recovery: Auto-saved work comes back after a crash.
Updates on your schedule: Install updates when you are ready, not mid-markup.
