In the late 1990s, ESRI (the GIS giant) had a deep relationship with Bentley. MicroStation SE .DGN files were a standard format for GIS data exchange. Many municipalities still have parcel maps, utility networks, and zoning maps locked in SE's version 7 .DGN format. GIS technicians often search for "MicroStation SE" to troubleshoot old data migrations.
A hallmark of MicroStation SE was its commitment to the . During this era, the DGN format was celebrated for its efficiency and "infinite" undo capabilities, which protected designers from data loss. Although Bentley eventually transitioned to the V8 format to overcome the 32MB file size limit and 63-level restriction of V7, many legacy systems in government and utilities continued to use MicroStation SE for decades because of its reliability in handling these V7 files.
