Amalgative Redline: five markup types on a drawing, listed with their type, author and colour

Amalgative Redline

Amalgative Redline is a PDF editor for markup, measurement and takeoff in the AEC industry. It runs in a web browser and on Linux and Windows. macOS is coming soon.

Amalgative Redline is in beta. It is incomplete, it will have defects, and it is not licensed for production work. Work on copies. Never open your only copy of a file in it.

What it does

Markup
The full tool set, with styles, and a markups list that is a real table.
Measurement and takeoff
Calibration, a three-tier scale cascade, anisotropic scales for civil profiles, and takeoff columns.
Documents, pages and sets
Work across a set, not one file at a time.
Interchange
Sidecar export in the format the established markup applications read, and a PDF round trip.
Automation
A command surface an agent can drive as well as a person.
