Esri's ArcGIS software helps you manage, analyze and display geographic data. Over the last few years, lots of these folks have had to jump through hoops to get their SketchUp models into Esri's ArcGIS as multipatch data. Placement was difficult, and once the models were in, there was no easy way to make edits to the multipatch geometry itself.
"With the recent release of the 3D Editor toolbar in ArcGIS 10's 3D Analyst extension, the process is a lot easier. Now you cann't only transform and place your SketchUp models into ArcGIS as multipatch features, you can edit your multipatch features using SketchUp 8."
