Q3D Scan is the companion app for AuraGO, the compact LiDAR device from Q3D Sensing. Connect AuraGO to your iPhone or iPad, and Q3D Scan turns it into a precise 3D reality-capture scanner for the field. Capture large spaces in a single session. AuraGO's long range, up to 30 meters (100 feet), covers more from each position, so you get through full floors, building interiors and exteriors, and entire job sites faster, not just what is within arm's reach. See your 3D scan build on screen in real time, clearly showing the areas you have already covered. Review your capture on site, and add to your scan to fill in any gaps before you leave. What you can do with Q3D Scan: - Capture detailed 3D point clouds with the AuraGO LiDAR device - Work fully offline, capturing in remote locations or anywhere connectivity is limited, with no connection required - Process scans right on your device, without long cloud-processing delays - Your data is never held hostage by a subscription and never trapped in a cloud that goes dark - You control your data: it starts on your device, and you decide where it goes from there - Measure directly in your scan, while on site - Export to standard 3D file formats, including DP, E57, LAS, LAZ, PLY, and PTS - Feed real-world 3D data into the CAD, BIM, and design tools you already use, for floor plans, models, digital twins, and more Built for professionals who work in real spaces: - Construction and engineering: document existing conditions, progress, and as-builts - Interior design: capture existing interiors to design from a to-scale 3D record - Civil engineering: record sites and infrastructure for planning and estimation - Utilities: capture equipment and facilities that are hard to measure by hand - Real estate: capture properties for asset tracking and space documentation Designed for AuraGO. Connect the AuraGO LiDAR device to capture at its full range, or scan with your device's built-in LiDAR when you are working without it. Compatibility: Pro-model iPhone and iPad Pro. Q3D Scan is a practical field tool that works alongside the rest of your kit. Reach for it when you need a reliable 3D record of a real space quickly, then export to the software that carries the project forward. Q3D Sensing builds Spatial AI tools that turn real places into usable 3D data. AuraGO and Q3D Scan are the first of them. https://www.q3dsensing.com https://help.q3dsensing.com
