Markups and dimensions

Mark up and measure the way you draw.

Click two walls, get a real dimension. Then cloud it, call it out, hatch it.

  • Snaps to the wall and lights it up before you click.
  • Scales per sheet and per viewport, never typed in.
  • Standard PDF markups anyone can open.
Check set

Check the whole set before it goes out.

It reads every sheet number, finds the drawing index, sorts the set and tells you what doesn't add up.

Reading sheet numbers…
7 sheets out of order A-202 is in the set but not in the index S-701 is referenced on S-101 but isn't in the set

Sorted for you

By the index, or your office's discipline order.

References checked

Callouts that point to sheets that aren't there.

Index vs title blocks

Missing sheets, doubled numbers, titles that differ.

Private by default

Shared only when you say so.

Your sets stay on your computer and work offline. Nothing is uploaded.

When a set is ready for review, pin it up. Only your team sees it, live, with replies and @mentions on every markup.

Why Romby Reader

What's different.

01

Made for architects

Built around checking and issuing sets, not takeoffs and estimates.

02

Checks the set

Sorting, the drawing index and broken references, which most markup apps leave to you.

03

Mac and Windows

Real apps for both, made to work together: the same tools and the same files, so a mixed office works as one.

04

Works offline

On site, on a plane, anywhere. No account needed, and nothing is uploaded.

05

Works with everything else

Your markups carry over to Bluebeam, Acrobat, Preview and other major PDF apps, and theirs open here.

06

Prints to scale

Full or half size, with the scale it prints at and a 3-inch bar to check it.
