OVERLAY allows teams to upload and share a project's drawings in one place, making email sorting, attachment filing and review tracking a thing of the past. Draw and review together in your browser.

Invite your in-house team or broader consultant group to a shared project. Streamline communication channels around a centrally located drawing set. See live cursor movement, follow collaborators, use the chat channel. Assign review items to team members and have them update its status when complete. Stay connected to your team and project through a single source of information.

OVERLAY deploys an advanced set of review features built on top of all your standard annotation tools. From simple geometry to advanced numbered comments and keynotes, OVERLAY has you covered.
Catch changes in drawings using the Compare tool - an advanced AI powered feature that compares drawing revisions and automates clouding of recognised changes. No more searching for tiny shifts in drawings.

OVERLAY incorporates a fully customisable material list with rates allowing teams to quickly and accurately conduct material take-offs. Your project has curves, splines, circles and arcs? No problem, OVERLAY is able to calculate areas, lineal metrics and volumes for all your project's elements.

OVERLAY is set up to be fully customisable. Use our favourites function to save any annotation's settings and contents. Export and share favourites with your team to remain aligned on message and aesthetic. Import .dxf files of your favourite blocks.
