OpenCities Map CONNECT Edition can attach Bing Maps as a raster reference or as a background image via the View Attributes dialog. To do this, the model must have a geographic coordinate system attached.
Select the View Attributes option, scroll-down to the Background Map tab, and select one of the options from the drop-down list.
Beginning with MicroStation Update 7 (and OpenCities Map built with that platform), the software did not require a Bing Map key from Microsoft. It is not recommended to use the Raster Manager | Bing Maps option any longer, as it is slower and takes more time and effort to configure.
To use Bing Maps in Bentley Map V8i, you needed a key from https://www.bingmapsportal.com/ to your application.
Once you've received your unique key, define the variable MS_RASTER_BINGMAP_KEY = Your_Bing_Map_Key.
You can then use Raster Manager to attach the Bing Map to the design.
