DGN, DWG, and DXF Files
You can create links to DGN, DWG, and DXF files. You can also create links directly to the contents of these files: design, drawing, and sheet models, references, saved views, drawing boundaries, and link sets. If you create a link to a model that contains a saved view or a reference, the link is automatically put in the Saved Views folder or the References folder for the model. You can also create a link to print set (.pset) file and to the contents (print definitions) of a print set file.
