KEY FEATURES: • Explore projects in 3D and 2D • Issue tracker: create and manage issues and stamps • Split view 2D | 3D • Augmented reality (AR): compare real-world installations with 3D models to check for discrepancies and see what is behind walls, floors, or ceilings • View object properties and add/edit custom properties as needed • Switch between appearance templates • Utilize 3D and 2D rulers • Overlay 2D on 3D and create section cuts • Navigate through 3D levels effortlessly • Navigation modes: use joystick, orbit view, and more • View point cloud data • Scan QR codes generated by desktop Revizto application to quickly access specific issues or 3D objects ______________________________ Here are some first reactions from customers that have tried the app: "Revizto's phone app puts the construction site in your pocket, making BIM accessible to everyone in the supply chain, from the CEO to the plumber. With a complete re-engineering, Revizto has realized a BIM vision and dream, bringing it to life now, not in the next 5-10 years. Everyone wins with Revizto!" - Jason Howden, Principal | Digital Innovation Leader, Warren and Mahoney "Extremely cool, something we have been waiting for a while now and can hopefully allow our field crews to readily adapt to the new age workflow." - Tanner Scholin, BIM Detailer, Murphy "Revolutionary app that will help push construction into the 21st century. A surprisingly quick way to view models from your phone!" - Jeff Kocinski, Associate/ Project Architect, SCB "I used the app for 5 minutes and definitely left thinking it would lead to more adoption in the field by our internal project teams as well as the subcontractors. Being able to fly the model with how light/easy it was, while going through issues in both 2D and 3D will definitely help." - Shaun Carollo, VDC Manager, Hoar Construction ______________________________ Don't have an account yet or want to learn more?
