It is now possible to add Bing Maps to your InfraWorks 360 model located everywhere in the world!
You can add Bing Maps to all your existing models, replacing the aerial you may have or simply add aerial imagery to a terrain surface you just created in Civil3D. Imagery can be used for commercial use and the area covered goes beyond Model Builder current limits.
This is a WMS service that streams down the imagery and cache it on your desktop.
Be aware of your surface size and your chosen resolution (typically we use Tile level 17) and also bandwidth for download time.The video below takes you through the process.
