ArcGIS for AutoCAD: "ArcGIS for AutoCAD is a free application that installs on top of AutoCAD 2007 and provides access to the results of all of the GIS mapping and geoprocessing capabilities performed by ArcGIS in the form of map service images. This application accesses dynamic georeferenced ArcGIS Server map services and displays them in the AutoCAD drafting environment. The included Identify tool gives users the ability to access feature attributes stored in the underlying GIS data sets. ArcGIS for AutoCAD leverages the ESRI tool set and geodatabase. The cartographic and computing power of ArcGIS is provided to the CAD user without the overhead of data management or the complexities of dealing with conversion and translation or thematic visualization of data. All vector, raster, and imagery formats that ArcGIS Server supports can be viewed in the CAD environment."
