For example, you can export your map to an Autodesk SDF file. This stores the geometry for each drawing object as data, so it can be shared with other Autodesk users in a small, portable format. When you connect to that file in AutoCAD Map 3D, all the objects appear on the screen, like AutoCAD objects. You can edit them using the same commands. However, the objects are now “features” and are stored in a data file, rather than in an AutoCAD drawing.
You can also publish your map to a DWF file. People without a copy of AutoCAD Map 3D can view this format using a free, downloadable viewer available from http://www.autodesk.com/designreview.
