SketchUp Make 2015
Powerful yet accessible 3D modeling software
Notes: There is no client to install for Bing Maps (previously known as Virtual Earth) as it is entirely web based. However, you can download the Location Finder utility which attempts to zero-in on your location more precisely, using WiFi access points and reverse IP lookups to determine your computer's location. Microsoft Location Finder is free, and can be downloaded from the Microsoft Download Center.
