Cubits app for iPhone and iPad

Cubits lets you download, view, and save 3D models from Trimble 3D Warehouse, or load your own KMZ files exported from SketchUp. Explore the thousands of high-quality models, including those from the Google Earth building layer, or show off your own projects.

• Pan, rotate, and zoom with intuitive, orbit-style multitouch gestures
• Choose your own background colors and style — a solid color or gradient between high and low "sky" colors with optional ground plane
• Pinpoint a models real-world location on a map
• Take screenshots to sync back to your computer or use in other iPhone apps
• Tweak many custom settings — toggle lighting, textures and axes, change backgrounds, or adjust advanced options like mipmapping
• Enjoy the carefully designed user interface
