CAD and GIS may look similar on the surface, but the underlying data models are quite different. It is difficult to translate GIS data to CAD and vice versa without losing information. The software industry has yet to settle on a common data transfer format. For the moment, DLG format is the most common public-domain GIS format. For some users, this may mean they have to purchase a separate data translator package to read the DLG or ARC/INFO data. CAD users may need to contact their software vendors to determine what solutions are available.
