As we build your custom HoloLens application, we make sure that the app supports all industry standard software, such as Revit and AutoCAD, and all its file formats, like IFC, RVT and DWG. This means you don’t have to create new file formats in order to visualize your existing 3D models on the HoloLens. Those models can be rendered on the HoloLens itself, as it is a standalone Windows 10 computer. However, to ensure high performance holographic experiences of complex 3D models while using the HoloLens, a traditional approach, which compresses the models and removes polygons, can mean a loss of important details. In that case, remote rendering is in order. In the field, this might require a 4G or 5G network connection. Luckily, with HoloLens 2 you can leverage the USB-C port to connect to a 4G, 5G or LTE dongle.
