Marking up drawings
on a Mac.
The most common question from Mac-based architects, answered plainly.
The situation
The established drawing-review and takeoff applications are Windows software. Where a Mac edition has existed at all it has usually been narrower than the Windows one, and several have been discontinued. That leaves Mac-based architects and engineers with four real choices.
Option 1 — run Windows on the Mac
Parallels or VMware on Apple Silicon, or Boot Camp on older Intel Macs. You get the full Windows application. You also pay for the virtualisation licence, a Windows licence and the application licence, and you give up disk space and battery life. It works; it is the most expensive answer.
Option 2 — a Windows machine or a cloud desktop
A second machine, or a hosted Windows desktop. Sensible if your firm already runs that infrastructure. Overkill for one person marking up drawings.
Option 3 — a general PDF editor
Native on Mac, good at PDFs in general, and most include a measuring tool. What they are not is takeoff software: no running totals as you draw, no deductions, no quantity summary grouped by subject, no building elements. For review comments they are fine; for quantities they are the wrong instrument.
Option 4 — a browser tool
The work is PDF geometry, and that does not need a native application at all. Redline runs in Safari, Chrome or Edge on any Mac — Intel or Apple Silicon, no install, no virtual machine — and does the review and takeoff work: calibrate a sheet, mark it up, measure lengths, areas, volumes and counts with live totals, take deductions, and export standard PDF annotations that other professional tools open and edit, so working with Windows colleagues is not a problem.
It installs as an app if you want it in the Dock, and it is $15 a month. You can open the demo on your Mac right now, without an account, and mark up the sample drawing — the fastest way to know whether it does what you need.
What you give up going this way
The firm-scale features: live multi-user sessions, batch OCR, and managing sets of hundreds of sheets. If those are your daily work, run the Windows tool in a virtual machine. If your daily work is reviewing drawings and pulling quantities off them, the browser is the simpler machine.
Try it on the sample drawing
Redline runs in the browser — nothing to install. Open the demo to try tools on a sample drawing. Demo edits are temporary; your own files, saving, signatures, exporting, printing and downloads come with the seven-day trial, which takes no card. After it you keep Redline Free, or choose Pro at $15 a month or $150 a year. Compare the plans.
