On the Autodesk Labs site, you can find a new free technology preview, Project Basejump, that enables AutoCAD Map 3D and AutoCAD Civil 3D users to access Microsoft Bing web mapping service (WMS) maps including aerial imagery, road, traffic, and other information.  Project Basejump is a FDO provider that enables you to bring Bing Maps layers into your maps, plans, and designs as a base layer.

Project Basejump adds a Microsoft Bing Data Connection to any language version of AutoCAD Map 3D 2013 or AutoCAD Civil 3D 2013.  The technology preview will operate until June 30, 2012.
