DGN File Reader

Autodesk Navisworks can read 3D DGN and PRP files from Bentley's MicroStation, but does not support CEL files or 2D DGN files. Referenced files and instances of cells are respected, and the Selection Tree reflects this file structure.

Note: The file reader supports files from MicroStation /J. It does not support MicroStation Modeler, MicroStation 95 or previous versions.
