The engineering archive is intended to be a permanent repository of engineering data. Data is not limited to MicroStation design files, but may include narratives, tab sheets, reports, and design notes.
Prior to archiving DGN files, use the Fix Range, Verify, and Verify/Repair tools found in MicroStation V8i SS4 on the ODOT Tasks under General | Tools. All DGN file should be compressed and the file visually checked.
