SketchUp, ArcGIS plugin
@Last Software has announced the ability to , offering GIS users the ability to rapidly create 3D models in SketchUp, incorporate the models in to their GIS database, and then display them in ArcScene and ArcGlobe, ESRI's 3D viewing environments. This allows users to visually explore the model in 3D, fly over the landscape, fly around buildings, go inside the buildings and look around, and then look out the windows of those buildings and see the landscape, all in the context of their GIS information. The SketchUp-ArcGIS plug-in enables the user to exploit SketchUp's modeling speed and ease-of-use to create geo-referenced 3D models, allowing users to extract geo-referenced coordinates directly from ArcGIS. The plugin is available for free.
