Reviewing construction models via HoloLens would be more useful if people could make notes directly on the 3-D images they were viewing. Trimble, a technology company that sells the popular 3-D modeling software SketchUp, lets people do that in its HoloLens app. Users can mark problem areas on SketchUp building models with circular virtual icons and record short audio clips explaining why they highlighted particular spots. Eventually, they might be able to use their hands to move an element within a virtual mockup and immediately see how the change affected the design, says Aviad Almagor, who leads Trimble's HoloLens business.
SketchUp Building Maker is an easy-to-use tool for creating three-dimensional buildings. Building Maker allows you to create buildings by combining 3D digital building blocks on top of two-dimensional (2D) aerial images (photos) just as real toy blocks might be combined to simulate a real building.
