1 Attach a Reference

As your design progresses, you will want to leverage other files. A DGN file contains one or more models. A reference is a model that is attached to and displayed along with the active model. References can be used for various purposes. For example, you can attach a map or floor plan to use as a background for your design. Or you can use references to attach multiple designs and details to a print sheet, creating a print composition.
You can reference models from the active DGN file or from other DGN files. You can also attach DWG, SHP, IFC and other files as references. After watching this video you will be able to leverage other files as references in MicroStation.
