Intergraph/Microstation Design v7 .DGN File Description
Surfer imports Microstation Design v7 .DGN files. DGN files are created by MicroStation and Intergraphs's Interactive Graphics Design System (IGDS). DGN files are binary CAD data files that include point, polyline, polygon, and text features with attributes. Surfer can also import v6 and older version DGN files. DGN files include file set-up information, graphic elements, and non-graphic data. Some feature style and color information is maintained when importing DGN files.
Surfer does not import DGN v8 files at this time.
