Polycam turns a single phone scan into the documents jobs run on: floor plans, as-builts, estimates, roof reports, claims files, measurements, and CAD-ready exports. No tripod. No technician. No two-week wait. WHAT YOU WALK AWAY WITH • Floor plans — 2D and 3D, ready for AutoCAD, SketchUp, and Revit • As-builts — weeks of documentation compressed into minutes • Measurements — every dimension in the room, in the time it takes to cross it • Estimates — priced off real conditions, not guesses • Claims and damage records — dated, dimensioned, defensible • 3D models and point clouds — .obj, .dae, .fbx, .stl, .dxf, .ply, .esx • 360° tours — shareable links for clients and remote stakeholders HOW YOU CAPTURE IT • 3D scanner for fast, accurate interior and structural capture that works without LiDAR • Photogrammetry and Gaussian splats from photos and video • Drone and aerial capture for roofs, exteriors, and whole-site coverage • Measure, annotate, crop, rescale, and label directly on the scan WHERE IT FITS IN YOUR WORKFLOW • Construction documentation and progress tracking • Renovation and design visualization • Insurance, restoration, and damage assessment • Site survey and drone-based mapping • BIM coordination and CAD workflows • Factory layout and equipment documentation WORK FROM ONE TRUTH Share scans and floor plans with clients and teammates by link.
