Trusted by hundreds of thousands of AEC professionals worldwide, Drawboard Projects streamlines design review workflows so your team can coordinate faster, reduce rework, and keep projects on track. KEY FEATURES PDF viewer and reader Open and read PDF plans, drawings, and documents instantly. Navigate large-format sheets with smooth pan and zoom, view multiple pages side by side, and work naturally on floor plans and other construction documents. Annotate, mark up, and redline Add annotations, markups, comments, and redlines directly on PDF drawings. Use ink, text, shapes, and callouts to communicate changes clearly. Every markup syncs to the cloud in seconds. Measure on drawings Measure distances and areas on calibrated sheets so markups and checks stay tied to the real geometry on the page-supporting field verification and takeoffs-style measurement workflows on your PDFs. Real-time collaboration Collaborate with your team in one shared workspace. All annotations and comments sync in real time so everyone sees the latest redlines and markups, wherever they are. Best-in-class ink and pen support Write and draw with Surface Pen or any compatible stylus. Pressure-sensitive ink delivers a natural, tactile note-taking experience on plans and documents. Drawing coordination Manage and coordinate drawings across disciplines. Compare revisions, track changes, and mitigate issues before they reach the construction site. Discussion and review threads Keep all discussions on the drawing itself. Review comments in context so every team member understands the decisions behind each change.
