DGN

DGN (design) is the name used for CAD file formats supported by Bentley Systems' MicroStation and Intergraph's Interactive Graphics Design System (IGDS) CAD programs. There are two versions of DGN: * Intergraph Standard File Formats (ISFF) specification, published in the late 1980s by Intergraph. This is sometimes referred to as V7 DGN, or Intergraph DGN. * In 2000, Bentley Systems created an updated version of DGN which includes a superset of DGN's capabilities, but which has a different internal data structure to the ISFF-based DGN. This version is properly referred to as V8 DGN.
