Bring your CAD designs to life in AR, improve decision making and get to market faster. TheoremAR enables you to visualize and interact with your 3D engineering design data in the real-world through your iPhone or iPad, whether that be from your office, a showroom, or your living room. MODES • Image tracking – Track 3D digital content against a chosen image target to place the content in a desired location. • AR Viewer – Use your environment and place 3D digital content on recognised surfaces to help visualize 3d models. • Model Tracking (target model) – Overlays the 3D digital content over an already created prototype. • Model Tracking (alternate model) – Overlays other selected content over the target model to view models within context. FEATURES • Manipulate your 3D model in the real-world by using the Manipulation box to move, rotate and revolve your model. • Scale your model to get a closer look at your design. • Hide and occlude parts and components to only see what is necessary. • Use measurement tools including point-to-point, offset and vertex snapping. • Display and review metadata for each component. • Capture screenshots of the current view of your model, mark-up your images and save to your device or server. • Enable world occlusion to see if models fit within their current space.
