When someone uses MicroStation, the information created is saved in a file format called DGN. If the same work were to take place in AutoCAD, that same data would be saved in a file format called DWG. Would the drawings or models look any different? Probably not.

The answer has little to do with architecture, engineering or other design functions and everything to do with the history and internal workings of the various CAD products. For more, please read our new article, "AEC CAD Leaders Say Plethora of File Formats Serve a Purpose."
